I am trying to learn R from a textbook and the data I am using is called College.csv, and it is found here.
The question from the textbook is
use the plot function to produce side-by-side boxplots of Outside versus Private.
I have tried
plot(college[,1], college[,9])
but I get a blank window along with some messages:
1: In xy.coords(x, y, xlabel, ylabel, log) : NAs introduced by coercion
2: In min(x) : no non-missing arguments to min; returning Inf
3: In max(x) : no non-missing arguments to max; returning -Inf
