Hi there,
I'm a new R user and I've got a little problem:
I would like to read several files at once (which works) and create R
objects for each individual file (which doesen't work) within a loop:
this is the way I've tried to program this:
fn<-list.files(path =
"/home/klimet/patrick/LAEGEREN/NEBEL/FOGEVENT2000/", pattern=NULL,
all.files=FALSE, full.names=FALSE)
for(i in seq(1,nfn,1)){
fin<-paste("/home/klimet/patrick/LAEGEREN/NEBEL/FOGEVENT2000/",fn[i],sep="")
fi <- as.matrix(read.table(fin,skip=1))
}
The i in fin and fi should create new objects for every loop with i
being the number, like f1, f2,f3 and so on. The way I did it, it reads
i as a character and overwrites the object in every loop.
Thanks for any hints....
Patrick

?assign, something like
assign(paste("f", i, sep = ""), as.matrix(read.table(fin,skip=1)))
Overwriting fn seems fine to me.
