Boxplots in R

In this vid, we use the qplot() command in the {ggplot2} package to produce gorgeous boxplots in R. Note: since I recorded this vid, the qplot() command has been deprecated. Check out • Better box plots in R ... for a more up-to-date approach.

The qplot() function still works but was deprecated in ggplot 3.4.0. Check out ua-cam.com/video/ETbFdSvPwUw/v-deo.html to make boxplots using the powerful ggplot() function!

Thanks

[@asiatyes1777]

this helped a lot, I have to use Rstudio to make a t test and I have never in my life used it lmao

[@EquitableEquations]

Yay! I'm glad it helped. I have a whole vid on t.test(), by the way:

Hi, thanks for your video! do you know how to delete the guide or legend that's in the right side (in your example says seeds and the color of each group)?

[@ayoubbensalih5774]

Did you find how to do it ?

Hello, I have a data that includes sampling timeline (August/September vs October/November), count of bivalves and gastropods in 4 selected beaches, and I want to create two graphs of boxplots with x-axis (sampling events mentioned above) and y-axis (mean abundance of bivalves, mean abundance of gastropods) and for the boxplots that could be filled with the colors of the four selected beaches( which are green= Mayaguez, orange= Rincon, blue=Anasco and red=Cabo Rojo) do you know how can do this in R? Thank you

[@EquitableEquations]

Hi! You could consider faceting to get side-by-side plots, or using both color and fill aesthetics to contrast the different categorical variables. I talk about some of these options in the second half of my vid on the ggplot() function:

How I can add min and max and average in the box plot representation???

[@samanthadesilva9740]

Hi, when I do this my data isn't automatically grouped (on the y) - it makes one big box plot for all my groups (so instead of casein, horsebean etc I get one plot for feed but using my own data)

[@EquitableEquations]

Hi! If I had to guess, I'd say that your data probably isn't in the correct (tidy) format. You may need to post your code on a Q&A site like stackoverflow to get specific help.

[@ask4joshua10]

how do we rearrange the boxes? very nice ..

[@EquitableEquations]

This is the most direct way:
qplot(x = factor(msleep$vore, levels = c("omni", "carni","herbi", "insecti")), y = msleep$sleep_total, geom = "boxplot")
I'm producing a more complete explanation of factors in R right now.

[@rajendraregmi2892]

very easy and clear video to understand. can you give me some idea to make box plot with two factors trestments?

[@EquitableEquations]

Hi! You can do side--by-side plots by including additional aesthetics like group, fill, or color. You might also consider faceting with facet_wrap or facet_grid.

[@rajendraregmi2892]

@@EquitableEquations can you write commands for that?

[@EquitableEquations]

For specific questions like this, consider the R4DS learning community, for instance on Slack.

Hi, how can i remove na values of my data in qlot?

[@EquitableEquations]

Hi! I use the drop_na() function from {dplyr} to remove rows with NAs. Honestly, though, if you're doing anything beyond basic plots, you'll want to learn the ggplot() function, which is much more powerful:

[@fasihakhan5319]

Video is admirable but backspace or deleting commands are not workable ... not user friendly

[@EquitableEquations]

Thanks for watching, Fasiha. This is a beginner's video, so I avoided all but the most basic tools. You can see something a bit more elaborate here:

Thanks sir.. But i hv no IQ for programming. I m phD scholar writing up but its hard for me to draw graphs by using commands..

[@fasihakhan5319]

@@EquitableEquations Sir hard for me as biologist has no aptitude for programing commands and having biological data

[@rajendraregmi2892]

@@fasihakhan5319 Again I am looking for two factors, can you just write command for two factors analysis. Thank for nice video.
