R help - Feb 2010 - graphing help: line runs off top of graph

Hi,

See the files at

http://bulldog.duhs.duke.edu/~faheem/R/

Usage is

$ Rscript memgraph.R meminfo.csv

Output is meminfo.pdf. As you can see, one of the lines (blue) runs off 
the top of the graph. Can anyone suggest a way to avoid this happening?

Please CC me on any reply. Thanks in advance.

                                                         Regards, Faheem.

mRSS = m[,c("time", "RSS")]
mVSZ = m[,c("time", "VSZ")]
mPERCENT = m[,c("time", "X.MEM")]
pdf(file=paste(strsplit(filename, "\\.")[[1]][1],".pdf",

plot(mRSS, col="red", type='l', xlab="time (min)",
ylab="memory (GB)")
lines(mVSZ, col="royalblue", type='l')
#plot(mPERCENT)
dev.off()
