Just recognized: On Windows there migth be an slash backslash issue. When you copy a pathname from Windows file explorer it gives you: C:\Users\Ika\etc.

[@marinstatlectures]

thanks for that +Ikarus2985 , i don't use windows and am not very familiar with it, so it's good to have that here, to clear it up in case others run into this issue.

[@nd.drones]

thank you

[@ragulvr9744]

should we use only forward slash for specifying the working directory and not backward slash? i.e only "/" and not "\"??

[@maziark3861]

Thanks for the great instructions. One suggestion... It might be better to have this video a bit earlier. Up to this video, I had difficulties in saving my working space and the progress I had sofar from previous videos.

[@marinstatlectures]

thanks for the suggestion +Maziar Karimi . there's always a trade-off when deciding the order to present material in. the reason we chose this ordering was to first allow the beginner to get used to the software a bit, and not overwhelm them with too many details before getting their hands wet. but id agree, that we could just as easily have them ordered differently.

[@geess5684]

Hi Marin, seems very simple when you explain. But all that I got just the first line correct: setwd(pathway). Beyond that, not able to change the name for simplifications. R responds by saying "cannot change working directory". Where am I going wrong? Thank you in advance

[@yuvenmuniandy8202]

Thanks for this video. I have questions: (a) Is it always necessary to set the working directory when starting a new session. (b) Can different files (Rmd, Rscript or Rdata) be stored under a same folder for one project? (c) Personally I choose to import my files from a directory rather the file.choose, as I always in the end like to knit the Rmd document to word or PDF. If i use file.choose to import, i always get error when knitting. I guess this is because in this way, a pop up window appears to import data. Maybe R couldn't recognise this when knitting. (d) could you please do some videos on absolute and relative path for wd. Would really appreciate if you can reply. Thank you.

[@mmebella4297]

Dear Mike, When I run the summary of z, for Smoke, Gender and Caesarean I get class and mode as "Character" and not the numbers visible in the video. Can you please help?

[@bwww2011]

Hi Mike, thanks for the video; I was wondering if there is a way to save the contents thats already input in the console? The load function couldnot pull that one off. Thanks!

[@marinstatlectures]

Hi +B Www , R wont be able to load what ever was entered previously into the console, only what it 'remembers' that you can see in the workspace. the way to save what is going into the console is to create a script of your code as you are working. i have a video explaining a bit more about this that you can check out if you want to learn more about scripts: kzbin.info/www/bejne/p6LdkHdnq9-Ga68

How do you change the working directory from cloud to local disc on Rstudio cloud online?

[@daniele1717]

best boy!

[@sumitkumarsain5542]

Hi Marin.. Suppose I have created many large datasets in one session and then I choose to save this workspace as image. Now will this image file occupy space equivalent to spaces occupied by those large datasets in total!

[@marinstatlectures]

sorry, i dont have an answer for this one, but id suggest to try posting the question on "Stack Overflow", and you'll likely get a good answer there

[@sanjeebkumar8539]

Hello Sir,Thanks again for this video.Yes I am learning a lot..I have to present a POC where I have to use R with PMML and then I have to use Data from Hadoop Eco system. Can you please help me out.

[@marinstatlectures]

Hi sanjeeb kumar , thanks for your comment. I'm sorry, but I am not able to help with your work, as I am extremely busy with my own work at the moment.

[@fisherman6246]

1. Read multiple json files into a working directory for further converting into a dataset. I have files text1, text2, text3 in the directory json . I dont know how to do it. please teach me how

[@nboruett]

Great

[@charitysmith1452]

Hi Mike, I am enjoying your videos on R, but i am having some trouble while I am working through this video. Every time I type in MeanAge

[@marinstatlectures]

Hi +Charity Smith , thanks! it is because in the videos, i have "attached" the data (so that R can 'see' the variables in the dataset. if you enter the command *attach(LungCapData)*, R will be able to recognize the variables, and the command you are entering should work. in the following video, i explain exactly why you are getting tis error, and the use of the "attach" command, etc: kzbin.info/www/bejne/Z3PGeKF-rLqHbM0 id also recommend watching our videos in order, as we have arranged them in a way that, while self-contained, each videos builds on the next. here's the link to the full playlist of R videos, if you wanted to check those out: kzbin.info/aero/PLqzoL9-eJTNBDdKgJgJzaQcY6OXmsXAHU

[@gm-123-0]

Do you know any method to get path for the standard wd? (not to set it)

[@marinstatlectures]

Hi +Giappoman , sure, just enter *getwd()* and R will return the path for the current working directory

[@gm-123-0]

And what about I want to get the default working directory instead of the current one? Is there any command to do that?

[@marinstatlectures]

if you start up a session, and just don't set a working directory, and instead ask for the path to the working directory, it will tell you the default. the working directory will be in the default location until you set it otherwise for a session. the default will usually be in the user account you are working in currently (e.g.) "Users/CurrentUserFolder"

[@gm-123-0]

It is not in "Users/CurrentUserFolder" (not on all the machines i am using). I need it later on, not only right after opening the session.

[@nicoleweigelt3938]

For some reason R does not let me edit anything in the console. Any idea why?

[@tanushreedutta9474]

I am not understanding why u have introduced projectWD. If I simply code it like this setwd("C:/Users/hp pc/Desktop/New folder") even then when I type getwd() I get the same result ..so what is the importance of introducing a new variable.Kindly explain

[@marinstatlectures]

Hi Tanushree Dutta , it's not necessary to do that at all, but can be useful for some things. the reason i do that is that sometimes you may be specifying the path to you working directory a few different places in your code. rather than type the full path each time, you can just save it in the an object called "projectWD", and then use that each time, rather than type out the full path to your working directory. but yes, it isn't really necessary at all.

[@tanushreedutta9474]

Thanks sir.. I got that and your lessons are really very nice

[@marinstatlectures]

thanks Tanushree Dutta

[@ujwaldey4270]

Why does RStudio on my pc always open with an already loaded workspace?

[@kengking2708]

Hi M.M., Could I just check on why there is an error in loading? read as; Error: in readChar(con, 5L, useBytes = Tr8e): cannot open the connection. IN addition: Warning Message: IN readChar(con, 5L, useBytes=True): cannot open compressed file "C:/Program FIles/Users/Rstudio", probable reason 'Permission denied'.

[@marinstatlectures]

Keng King sorry, but i can't figure this one out from a distance. is the file in your working directory, so that R can find it? also, it sounds like it's a compressed file...can you just uncompress the file, and then have R open the uncompressed file? id suggest trying out some of those. it can be difficult to debug from a distance, without context. good luck.

[@diyashah9528]

What should I do? Untitled1 coming again and again. I am unable to set working directory. I need some more

[@marinstatlectures]

You will have to be a bit more specific, from your comment I have no idea what you’re issue is

[@The075satyasai]

can u plz do this specifically for windows ??it is showing lots of errors

[@marinstatlectures]

Hi +Satya Sai , i'm sorry but i don't have or use Windows, so am not able to record anything in the Windows environment. but i can suggest this...if you work in RStudio, there should be a *Session* menu, if you go in there, there should be an option for *Set Working Directory...* , an d from there you should be able to set it up using menus, and not commands. try that out, and hopefully you are able to navigate your way through that. good luck.

[@The075satyasai]

Ok thank you sir!!

[@sashasasha100000]

Each project should have .rproj file. It location is your root directory of project. From here you can use relative paths to different folders. No setwd() needed whatsoever.

[@NomisIsGozulike]

Ok so for anyone who had issues with not being administrator on his Windows based computer. I had issues changing the directory with messages like "cannot change directory". You cannot use a folder which contains your operating system, so generally your SSD. This has caused countless issues for me to even get programs running properly and also R suffers from this. And people wonder why Apple has a market.... fk MS honestly (this has been an issue for years now)

[@Venisor21]

There's one thing I don't understand. If you can use "=" to assign a value to a variable, why does everyone use "

[@superstar3179]

When I save the workspace they say no working directory found.

[@marinstatlectures]

it's hard to troubleshoot things like these from a distance, but here are some things that may help. have you tried setting the working directory? if you enter *getwd()* R will tell you the current working directory. if you are working on a work computer (or in a guest account or different user account on your computer) you may be trying to save to a working directory for which you dont have permission (or dont have write access). those are a few things id suggest to check... good luck!

[@superstar3179]

@@marinstatlectures I have windows 10 in my computer and when I save the workspace it says no working directory found and windows defenender message comes and it says access blocked. How do we deal with it ? Although your lectures are very good but I am some problems in it .

[@marinstatlectures]

I'm sorry, but i dont work with windows and dont know how to solve that issue. but it sounds like it is a permission thing (as it is saying access blocked). one suggestion i have is to try setting the working directory to something else (you can test it out by setting it to the desktop, as you should have access/permission to that)..id say try that out and see if you are not blocked there. and also try talking to someone with more knowledge of windows, as they may be able to offer better help.

[@hellochii1675]

When I try setwd, I got this error: Error in setwd("~/Desktop") : cannot change working directory However, I tried :> setwd("C:/Users/chichi/Desktop") # It works. Can anyone helps me?

[@marinstatlectures]

it sounds like your computer may have different user accounts? and using the first command, it's not clear which desktop to set the working directory to. in your second command, you specify the full path to where you want your working directory.

[@hellochii1675]

Thank you so much for your help.

[@latin_prologue]

What is the difference between R and Rstudio?

[@marinstatlectures]

Hi Kaustubh Joshi , R is the software, and RStudio is just user interface that sits on top of R and makes it more organized. (e.g.) if you open up just R, you get just the console. if you produce a plot, it appears in its own separate window, and if you want to work with a script, you open that in another separate window. RStudio organizes all of these...you get the console in one "payne" and you get the plots in another, and the script you run is in another. its just a way to make R more organized. i would recommend using it, although it isn't completely necessary. you will have to install R and RStudio, to use RStudio. once both are installed, opening up RStudio will open up R in the background.

[@latin_prologue]
