Perhaps:
somfunc<- function (file) {
fname <- deparse(substitute(file))
aa_som<-scale(file)
final.som<-som(data=aa_som, rlen=10000, grid=somgrid(5,4,
"hexagonal"))
pdf(file=paste("/home/cdu/changbin/", fname, ".pdf", sep="") #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?
This seems to be a popular question this week. You should read more of
r-help.
