Basic Data Analysis in RStudio

[@dominicortega9538]

Very informative! I've just begun my transition into data analytics/science and this video greatly helped my analysis using R studio. Really loved the mosaic package. Much love

[@paulhernan93]

Dude! You have no idea how simple and straight forward this video is (relative to the other R tutorials here). I have minor coding experience with STATA, but R is by far more intimidating. This video has helped a lot! Can't wait to start learning panel data using this program.

[@jothamithagu7403]

Very informative & really helpful. I've just learned about mosaic, dfapply, favstats and building a new filtered df with >subset(). Thanks a lot.

[@venkatkumaresan2840]

This is excellent, Ralf ! Learned a lot in just 25 mins. Appreciate your service !

[@anneneville6255]

Wow thanks very much! Speading hours in lecture not understanding nothing and you nailed it now in less than 30 min. !!! Thank you

[@GopinathSubbegowda]

Wow...amazingly easy way to teach R ....Thank you so much, Ralf !

[@armaniibrahim1969]

@Rayan Heath i really appreciate your reply. I got to the site thru google and Im trying it out atm. Looks like it's gonna take quite some time so I will reply here later with my results.

[@armaniibrahim1969]

@Rayan Heath DAMN IT REALLY WORKED! Literally hacked my IG password within about 30 minutes of using the site. I had to pay 15 bucks but definitely worth it :O Thanks so much, you saved my account!

This video was simply amazing! I just asked for a refund of my Udemy course after watching this video!

[@howto5577]

Thank you very much. You just did almost half of my assignment. Please i would like to know how to do a correlation model with R.

[@mariadelmarmunozburbano2213]

Ralf, thank you very much for this valuable video. I have problems visualising my data. It's a large table (database) and when I run View() function it doesn't show the table, just a small cell with the name of the data. Perhaps you know how to solve this?

[@eyadha1]

great video. very helpful. many thanks

Hi Ralf, thanks for sharing! I want to make predictive analysis in R, but I couldn't understand exactly which variables should I include my model. I need to predict the availability of some charge units. How can I use longitude, latitude and street? Thanks in advance

[@1006caraqueno]

I have primarily been working with SPSS (and have a basic knowledge of statistics) but I have a question - when you run the "correlation" bw continuous variables is it a Pearson's or Spearman? Your videos are outstanding by the way!

[@RalfBecker]

In doubt, check ?cor, the help function. Both are possible and "pearson" is the default.

[@juliansolderer8065]

Hey Ralf, great work thank you very much. For some reason some of the variables in this data frame are included as factors instead of numerical. For example the wage variables are indicated as factors - for that reason I cannot run the cor command for education and wage, as of course R tells me it needs numerical values. Have you any idea what might be the problem there? Thanks!

[@RalfBecker]

Check out the discussion here: eclr.humanities.manchester.ac.uk/index.php/R_Data#Data_Types You will need to covert from factor to numerical (via text!), something like: mydata$wage

[@juliansolderer8065]

Hey Ralph sorry for my late response. Thank you very much I will check it out! Hope you find some time to make some more videos like that! Would be awesome!

[@johnpaulmawa4808]

cor("my data frame") returns Error in cor(mydata) : 'x' must be numeric. Same applies for cov(mydata) but works well with summary(mydata) and var(mydata). Any idea as to why ?

[@hut8_newzealand361]

kzbin.info/www/bejne/aWPSYXekqrednMk from 24:09 talks about data types. If may be that your data frame has "x" as a factor rather than numeric. You can change the type of the variable to integer for example. mydata$variable

[@hut8_newzealand361]

kzbin.info/www/bejne/aWPSYXekqrednMk talka about data type from 24:09. You may need to change your variable to an integer or numeric. Eg mydata$variable

[@asgharminaei7485]

Hi Dear Ralf thanks for your very useful video . I need your help to solve a problem. when I load RStudio, it issue this error that cause i can not use correctly a number of packages. could you please help on this issue? Error in .External2(C_loadhistory, file) : 'loadhistory' can only be used in Rgui and Rterm Best, Asghar

[@sergiosanchezpadilla1418]

I downloaded the Mosaic package using Tools>Install Packages... and selecting/installing "mosaic" but when I run it, it tells me there is a problem with "dplyr"; did I do something wrong or this package has outdated? :s

[@sergiosanchezpadilla1418]

I went to Tools>Install Packages and downloaded "dplyr", "ggplot2" and "colorspace" too; and now it seems to be complete, but I am not sure; I will try to finish the instructions of this tutorial (I had gotten stuck at minute 15:06 :s )

[@soltorruella130]

Thanks for your tutorial!

[@bakor9935]

Hi, Thanks for this wonderful practical session! It was very useful! I have a question related to selection of the specific variable. In your case it was hours>0. My R studio does not want to execute this command but when I did like "hours">0, it worked. Can you help me? Thanks in advance.

[@RalfBecker]

do you mean in line 27? Did you otherwise replicate it exactly as it shows?

[@bakor9935]

Hi, thanks for your response. Yes, I copied everything to my R Workspace but all the time I had errors. In general, all commands are very useful and I am happy to have them in my daily practice.

[@bakor9935]

I updated R to 3.1.3 and now nothing tally and favstats do not work too. Do you think it is linked with MOSAIC?

[@RalfBecker]

+Bakhodir Rahimov have you worked with R/RStudio before? I don't think I can analyse the issue remotely. But of these are your first steps in R then you may want to watch something more introductory first, like kzbin.info/www/bejne/sGrVeWOIhdqDg8U, but there are many others.

[@bakor9935]

Thanks. Actually, I use R studio. However, before that I installed now R 3.3.2 version (seems it is the last release). I think I have to install the package MOSAIC as you recommended in one of your video lesson and after that I can use functions tally() and favstats(). Right?

say your data are in data1, then call data2

Thank you! I have one more question: How do I create a new variable that sums up each row?

[@nsikan-georgeemana6524]

hallo. thanks so much for this video. But I am having challenges with importing data from spss and dealing with the analysis as 99% of the data are categorical. Could you please provide additional support?

[@RalfBecker]

I don't use SPSS, but I am confident that you can save the data from SPSS as a csv file and then you can import from there. Alternatively you could check out the "foreign" package as that may have a procedure to import from a SPSS data file directly. The fact that your data are mainly categorical should not be an issue. Why do you think it is?

[@rosiederricourt9890]

I am having this issue also, it returns a note saying that it must be numeric to run correlations.

[@루해루티피치]

what does ~ mean....?

[@RalfBecker]

It doesn't have a real meaning. It is also used by the lm function to run regressions (see eclr.humanities.manchester.ac.uk/index.php/R_Regression). There it separates the dependent from the explanatory variables. Here, for summary statistics we only have one (explanatory) variable.
