R help - Apr 2010 - help output figures in R

somfunc<- function (file) {

aa_som<-scale(file)


final.som<-som(data=aa_som, rlen=10000, grid=somgrid(5,4,
"hexagonal"))

pdf(file="/home/cdu/changbin/file.pdf") #output graphic file.

plot(final.som, main="Unsupervised SOM")

dev.off()

}

I have many different files, if I want  output pdf file with the same name
as for each dataset I feed to the function somfunc.

HOw should I DO?

THANKS!

This seems to be a popular question this week. You should read more of
