Ivan,
Try this:
eval(parse(text=paste("save(file", i, ", file=\"file", i, ".RData\")", sep="")))
...Tao
Or just use 'list=' like this:
for (i in 1:4) {
temp <- data.frame(a=(i+1):(i+10), b=LETTERS[(i+1):(i+10)])
filename <- paste("file", i, sep="")
assign(filename, temp)
save(list=c(filename), file=paste(filename, ".rda", sep=""))
}

Subject: [R] save in for loop
Dear users,
My problem concerns save() within a for loop.
Here is my
code:
for (i in 1:4) {
temp<- data.frame(a=(i+1):(i+10),
b=LETTERS[(i+1):(i+10)])
filename<- paste("file", i, sep="")
assign(filename, temp)
save(filename, file=paste(filename, ".rda",
sep=""))
}
As you can see, save() doesn't work as I would like: (1)
the object saved is called "filename" (instead of "file1", "file2", etc), and
(2) it of course contains only the name (as character) instead of the
data.frame
How can I fix it?
