Density Plot in R with ggplot and geom_density() [R-Graph Gallery Tutorial]

In this tutorial I show how to create Density Charts in R with ggplot() and geom_density(). The examples are based in the R-Graph Gallery. I show how density charts are different form histograms and how to visualize multiple different distributions at once.
I also describe how to annotate them and how to add them to the margins of scatter plots.

I love this video. Visually appealing charts, but the explanation is clear and concise. This is a perfect explanation and guide, thank you!

[@TheDataDigest]

And I love your comment. Really glad that it is so highly appreciated by you. I hope to make many more such videos and that they will find subscribers like you that will watch and enjoy them.

[@m3ick]

Your tutorial is very informativ. Keep up the good work!

[@suying-meow]

Thanks for your tutorial, it will be better if you can add more details about what each code means.

[@chikuniepraise3481]

I loved the tutorial. Thank you so much

[@TheDataDigest]

Thank you for this nice comment :)

[@bhargavapothakamuri4218]

Dude this is awesome !!

[@TheDataDigest]

Thank you very much. I will soon upload a new video about the geom_ridgeline() function that combines density plots in a different way.

[@AnseloSilver]

I like this tutorial, it has a good pace and explanation going along with the step. I have seen some tutorials going too fast.

[@TheDataDigest]

Feedback like this is highly appreciative. Thanks for leaving a comment. I do cut out all unnecessary speech so my videos are actually quite fast. But I want to show a lot and one can always rewind and watch again.

[@dra.thaisdinizreis]

thank you!

[@portillanath]

Thanks a LOT!

Thanks for subscribing. Next video will come out this weekend.

[@keylavitoria2588]

Obrigada!! Vou tentar fazer !!

[@TheDataDigest]

Eu te desejo sucesso! Obrigado pelo comentário. [Google translate]

If you were to add lower and upper bounds as shade to the density plot (density on the y axis) as ribbon, how would you do it? I am asking this because I am stuck with a similar problem for myself

[@suheylaaydemir8728]

thank you for the great explanation & the background music is distracting

[@DomenicaJosefina]

Could you tell the names of all the libraries you use? :)

[@TheDataDigest]

I think in this video I only used ggplot2 library. It is part of the tidyverse package, which also includes dplyr. I also often use forcats (to work with factors), lubridate (to work with dates), and stringr (to manipulate strings).
I also saw this tweet today about using ggdist package for distribution plots (twitter.com/MatthewBJane/status/1780952366541385910).
Hope that helps :)

Thanks bro !
Can you gimme your email, I have a question regarding gather and spread. And also Transpose function (curiously the transpose function is changing DF to a Double type)

[@TheDataDigest]

Hi Bhargave, I recommend to go to "stackoverflow" and post your questions there. If you give a reproducible example you will get solutions and answers within a few days by competent users. Maybe I even see your question there and can answer it. Thanks for watching my videos.
