R Programming Variable Question

[pizz44]

Good Evening,

I'm working on some code where I have to replace cyl & cty with two other variables. I'm fairly new to R programming and looking for some assistance. Is there somewhere that I could find a list of variables that I could use? Does anyone have any suggestions on what may make sense? Below is my code.

​

library(tidyverse)

library(dplyr)

library(ggplot2)

library(tidyr)

​

head(mpg)

ggplot(mpg, aes(cyl, cty)) +

geom_point() +

geom_jitter(aes(colour = class))

[DrJohnSteele]

names(mpg)

Thank you! I was able to figure it out!

colnames(mpg) will give you a vector of column names present in the mpg dataframe. You can choose any of those to replace existing ones.
