If these are the only files in the directory, then you might try...
(File paths will need to change if the folder "200209" isn't in the
working directory)
fpath <- "./200209"
a <- list.files(fpath)
for(i in 1:length(a)){
assign(paste("y",i,sep=""),read.table(paste(fpath,a[i],sep="/")))
}
Another option is to put them in a list...
for(i in 1:length(a)){
y[[i]] <- read.table(paste(fpath,a[i],sep="/")
}
or with lapply...
y <- lapply(1:length(a), function(i) read.table(paste(fpath,a
[i],sep="/"))
Hope this helps.
Cheers,
Derek
