R help - Sep 2007 - saving results under specified file name

Hello,

I would like to save the results in a specified file name.  Here is a test
example:
 

aa <- function(xx, newname) {
 yy <- xx^2
    rdName <- file.path(paste(newname, ".RData", sep =
""))
    assign(eval(newname), yy)
save(newname, file=rdName) ## FIXME
}


aa(3, "test")

load("test.RData")
ls() 

I would like to see test (which should store 9) rather than newname (which
stores "test")

Please let me know how to do this.

Thanks.
-Nitin

so you need save(list=newname, ...).

Thanks Professor Ripley and Professor Harrell.

Yes, save(list=newname, ...) works.

Best,
