Hi,
I am trying to transition a system based on dynamic image generation (via R)
from our development system to a production environment. Our R script
functions as expected when run by a regular user. However the script dies
when calling the png() function, when started by the webserver user.
Thanks David. I reduced the data set and its copied below (also attached to
this email as text file). Now N=50, Only 2 years, Only 2 Cities. I tried:
foo-read.table(SampleData.txt, header=TRUE)
boxplot(foo$admit ~ foo$city + foo$year, col=2:3)
I need some help with:
