R help - Jun 2011 - Variable in file name png

Hi,

I'm having trouble with getting the png function to properly produce
multiple graphs. RIght now I have:

for (z in data) {
 png(file=z,bg="white")
 thisdf<-data[[z]]
 plot(thisdf$rc,thisdf$psi)
 dev.off()
 }

Which should take the "data" object, a list of data sets and produce a
graph of each with respect to the two variables rc and psi.
I want the names to change for each graph, but am not sure how to do it, any
help would be apreciated.
Thanks,
-Acoutino

you probably meant for(z in seq_along(data))

and the rest should be fine.
