Thanks for the tip on "cut," seems like it should work. I must still be missing something, though. Here, I'm cutting on the y variable, then attempting the boxplot:
cutRPKM <- cut(count$RPKM, breaks=4) head(cutRPKM) [1] (-0.0995,24.8] (-0.0995,24.8] (-0.0995,24.8] (-0.0995,24.8] (-0.0995,24.8] [6] (-0.0995,24.8] Levels: (-0.0995,24.8] (24.8,49.8] (49.8,74.7] (74.7,99.6] boxplot(as.numeric(cutRPKM)) This gives me a single box instead of five boxes. ?? Thanks again, --Kelly V. ________________________________________ From: David Winsemius [[email protected]] Sent: Friday, December 09, 2011 11:14 AM To: Vining, Kelly Cc: [email protected] Subject: Re: [R] scatterplot to boxplot translation?
