Bar charts and Histograms using ggplot in R

To create a bar chart or histogram using ggplot is easy. Bar charts (or bar graphs) are used to visualise a single categorical variable. Histograms are used to visualise a single numeric variable. Ggplot2 is a powerful package used for data visualisation in R programming. So if you're into data science, statistics or any other quantitative analysis and you're learning to use R, then I recommend that you learn ggplot. This is part of the series: R programming for beginners. ggplot is sometimes referred to as ggplot2

Frankly, one of the best tutorials for R. Thank you for making Visualization with R very easy.

I have no words, these lessons get better and better from one another. The way you explain every concept, and the way in which you remark every important information is simply astonishing. I'm learning my way in R and ggplot at a surprising speed all thanks to you.
Again, no words. Keep up and thank you for your work.

Incredible intro! Keep the videos coming and would love to see more videos on organizing the bars by frequency since that is typically how senior management wants to see the data visualized

[kumarsatyam]

Amazing videos on ggplot. I really love the passion with which you teach. Goes to show how much you enjoy this!

[FitnessAndLifeWithLaShelle]

You've answered 50 questions that were floating around in my head in the first 6mins of the video! God bless!

[LiahBrussolo]

Very clear explanation of the meaning of each bit of code, thank you!

[AmerikiDork]

I love these videos. This makes R seem very intuitive and user friendly.

This is so so helpful, I wasn't aware of being careful about which NAs I'm dropping. I got introduced to the pipe operator in some of your previous videos and I'm just loving it!! I agree that it's really nice to use the pipe operator with ggplot. Thanks for the great videos!!

Fantastic videos, you have made my life a lot easier. Could you perhaps create a video on how to create contingency tables, unless I have missed it. We use them quite often in epidemiology.

Thanks Greg - just subscribed. Hopefully we will have a steady stream of content as you are an excellent educator!

[tbaerg]

fantastic video. I'm quite guilty of being over enthusiastic with my drop_na; so this was a great reminder. Kudos!

[lukeskinner]

Thank you for these videos they are very well explained at a great pace, please keep making more!

[Pontustilrem]

Thanks for a great lesson. Any possibility of showing how to extract data for doing a chisquare test in R?

[faisala.alghazwi]

I think it's time for me to get back and learn R. you sure seem to explain well for beginners. Subscribed

this video is help for me!! I'm a year 3 unverisity students, this semester I have a data analysis course and that was really hard for me. looking for video about using R to inference the data~ Thanks!!

[吴建-iy]

Awesome looking forward to more videos thanks a lot

[mariapapanikolaou]

You're great and inspiring!! You help a lot! But... could you please tell what code I should add so that the number of cases in the y axis is not presented in scientific form?

[fridab]

your videos are so useful for getting started! thank you!!

[lindasturm-flores]

Thanks for another good lesson in R.
I would like to see a video on ANOVA in R. Thanks again!
