Using ggplot to create bar charts for 2 categorical variables. R programming for beginners.

[@Ruostesieni]

Absolutely love these videos of yours! Keep it up! Wanted to change away from SPSS to R for my doctoral thesis and your videos have given me the motivation AND means to do it.

[@kiwookkim_WookLab]

haha always love it when you end with "don't do drugs, don't ever change". Fantastic resource for R beginners like myself, thank you!

[@RProgramming101]

haha - glad you like it.. :)

[@HomieCV]

Currently doing my Google data analytics certificate and I really enjoy adding to my knowledge with these videos. kuddos on your teaching abilities.

[@saradhiananth1613]

Bro, Is that analytics course free ?

[@HomieCV]

@@saradhiananth1613 I payed for it. I was able to finish it in two months by committing to 5-6 hours a day. I heard there is financial aid available but I am not sure how that works.

[@MrRubyElf]

Oh my god thank you so much, you have no idea how long I've been looking for how to separate the bars by different variables. You also made it clear what pipes are. Thank you!

[@RProgramming101]

So glad it was helpful! Thanks and cheers :)

[@moneeanalytics]

I'm taking my Msc. Statistics and am glad for your R videos Very instrumental. Keep up Sir

[@RProgramming101]

Thanks :)

[@perpetuankeseifiemor6475]

Wow!!! Amazing video! R simplified!!! Am glad I came across this video! Makes R more interesting and understandable! Thank you so much!!🙏

[@RProgramming101]

Glad you liked it!! Thanks!

[@edongoogle8290]

My favourite channel! Please do an analysis of variance (ANOVA) test for three related data sets of different sizes, including numeric and categorical variables. That would be brilliant.

[@deeptimittal6547]

Very nice explanation which is very easy to understand.

[@ousmanelom6274]

The best teacher in R with you it become easy

[@RProgramming101]

Thanks for the very kind comment

[@daameya]

Excellent Video. It was very easy to understand and helpful to complete a class assignment. Big Thumps up.

[@someone8116]

Very informative video. Would suggest for a follow up video that includes adding error bars to the graph, as well as, significance indicators (previously calculated letters or asterisks) above each individual bar. This would be helpful in the cases where the is a single and 2 categorical variables.

[@epeliloganimoce6651]

Great explanation: short, succinct and intuitive

[@RProgramming101]

Thank you kindly!

THANK YOU. really helpful for my poli sci project AND this is making me want to get into R for its own sake

[@RProgramming101]

You can do it! Glad it was helpful! Thank you :)

[@dominiquebarrette9621]

Really excellent communicator bravo and thank you so much

[@RProgramming101]

Thank you for the feedback, I really appreciate it!

[@12fra12nk]

Hi dear, i tryed for hours did something like that in some seconds of video you explained exactly what i whant. thank you

[@RProgramming101]

So glad to hear that! Thanks.

[@bbluca94]

Amazing videos, keep up!

[@RProgramming101]

Thanks, will do!

[@JosephSila-t2e]

I love this video.. Amazing!!

[@leakopp6547]

the 1 minute gave me a lot of hope :D

[@sushilojha5202]

Thank you for making R easy to use😊

[@dr.pervaizahmaddar9662]

Thank you. How to add labels on top of each bar?

[@Simba-The_Lion]

Learning a lot here feels easier and understandable.

[@RProgramming101]

Happy to help! Thank you for the feedback.

[@GnarTank]

I made a bar chart today. Thank you

[@RProgramming101]

Wonderful!

[@harikathi2089]

Super helpful! Thank you!

[@RProgramming101]

You're welcome! Glad you enjoyed it!

[@ninafulep4707]

Amazing video! I don't know what I would've done without them, you make R actually fun! I was wondering, in which video do you talk about adding labels to amounts in a stacked barchart? thanks!

[@theexpatteacher8255]

Thanks so much for an awesome video. I really like using the pipe operator which, as you said, cuts down on creating more objects. My code is cleaner now and easier to follow.

[@RProgramming101]

Agree... I LOVE %>%

[@yogawithmichellejulie]

Thank you so much for explaining everything so well! You're a real life-safer :)

[@RProgramming101]

Happy to help! Thank you :)

[@abdulmusa6162]

Awesome many thanks for the update

[@RProgramming101]

you are most welcome

[@syedatasneemfatima7062]

Videos are great help ... thank you.

[@rileykent5670]

I followed this step by step and ran the code but it came back with "error: object 'sex' not found". Any idea what went wrong for me?

[@pukroy]

I got a problem in this starwars dataset here it is library(tidyverse) > View(starwars) > starwars %>% + filter(hair_color == "black") | + filter(hair_color == "brown") %>% + drop_na(sex) %>% + + ggplot(aes(hair_color, fill = sex))+ + geom_bar(position = "dodge", + alpha= 0.5)+ + labs(x= "Hair Colour", + y= "Number", + title = "Hair color of star wars")+ + theme_bw() Error: object 'hair_color' not found #I don't know why "hair_color" can't find #may be its a big mistake by me #I have a big question please help

[@Fly_maggot]

Can I know how to overcome error bar overlap when producing a stacked bar chart ?

[@usleoru]

Very nice!

[@RProgramming101]

Thanks for the feedback!!

[@XploreBioinformatics]

Can you please show how to add labels to the bar when we use position = "fill"?

[@andreferreira7873]

If I have data where the are 3 columns ( one is a factor and the other two are numeric values) can i do a bar chart with 2 categorical variables ? for example the x-variable is the name of people of the study and y-variable have the values of the other two colums which are the heights of two diferent years

[@jalepezo]

thank you very much! precise and to the point

[@tarkbugraasc2446]

Can you explain the reason why nonlinear regression crashes due to the use of unreasonable initial guesses of coefficients?

[@jababnamgay6366]

My bar plot in ggplot shows NA although there in no NA or missing value in my data. How do I solve it sir

[@zafarsongs]

I need to understand basic the Name of my parameter Can i use " AD+CD-BD_love"???

[@omerzahoorchughtai7089]

I have to create a bar chart which shows cost of different machines per year.lets say the years are 2018,2019,2020. How can I plot the chart with the data available.

[@ahmed007Jaber]

i have this set that has numeric variable and two categorical variables. I did everything fine except the legend is done in gradient colour fashion; scale of colour and values while it should be 2 categories either 0 or 1, any ideas? db %>% ggplot(aes(x = age, group= loan_default, fill = loan_default)) + + geom_boxplot(alpha=0.7)+facet_wrap(~ employment_type)+coord_flip()

[@draprincesa01]

same here ....it´s a factor !!! just put before your variable the word factor and perentesis for example for variable a und b db %>% filter(a %in% c('1','2','3')) %>% drop_na(b) %>% ggplot(aes(factor(b)))+ geom_bar(aes(fill=factor(b)),alpha=0.5)+ facet_wrap(~ a)+ theme_bw()+ theme(panel.grid.major=element_blank(), panel.grid.minor=element_blank(), legend.position='none')+ labs(title = 'titel', x='Transport', y='count')

[@kwetynasc4764]

Great videos! Could you post tutorials on Inferential statistics and Biostatistics with R? Much appreciated!

[@ricardoansantos]

Another fascinating video! One question, can we used ggplot to perform graphing that are usually embedded in other packages? For instance, the age modelling package Bacon?

[@RProgramming101]

Great question - I think so (but am now sure). Will see what I can find out)

[@rajendraregmi5407]

Hi I love your short and sweet videos, I am wondering how can I prepare Bar chart with more than one numerical variable?

[@anisoleanime2568]

Absolutely love the videos! How can I create a weekly schedule using ggplot2? Could you make a video on that?

[@jerrynyameye1031]

My favourite teacher of all time...love you sir keep up the good work I have a question and that is how do you visualise your data after cleaning...? I filtered a datafram and use mutate function to add new row to the datafram After which I wanted to use ggplot2 to visualise my data but it throwed an error message saying object not found thus the new row I created not found

[@splham]

how can i get a personal class from you?

[@sitinabilah7954]

Can u explain how to do Non MultiDimensional Scaling using R please.

[@zhenhuahuang291]

Can you create one for ANN using R Keras?

[@nurmuhammad2072]

Sir, would you please make a video on Chi-square test in R? Your videos surely helped me import dataset in R and do further analysis.

[@RProgramming101]

Hi Nur, Chi squared test in R video is to be published today. Hope all is well!

[@DK-sm5wf]

the explanation in regrads to the equal signs threw ,e a bit off, ususally "=" means youa ssing a value, since you want to filter an assignment would be pointless hence you want to access the assigned value of said variable which you do with "==" but the logic in regards the what to do comes from the filter function, so attributing the "if" to the "==" may be not 100% correct as the actualy filtering happens through said function, you simply check the value with the "==" and decide according to the defined logic.

Hello, you should not use the noisy musical background in a short and important academic video, it spoils your presentation, please remove.

[@aliqzakry834]

Why are you always using tidyverse? It's so infuriating. I'm not here to learn tidyverse. I'm here to learn R

[@Ben-fk1dl]

Bro what😂 you have to load in what codes you’re going to use and tidyverse is the most common
