writintg wrappers around save()
From the help page
The names of the objects specified either as symbols (or character
strings) in '...' or as a character vector in 'list' are used to
look up the objects from environment 'envir'.
The default for envir is parent.frame(). You want to change it (and watch
out that default and explicit arguments are evaluated in different
places). One approach is
save.verbose <- function(..., file, envir = parent.frame())
{
cat("save.verbose:", file, "\n")
save(..., file=file, envir=envir)
}

Dear R-users,
I am trying to write a wrapper function around save() that will report the file which is being saved to.
So I thought that the followintg would do the trick, but it doesn't. I understand that 'y' is somehow not visible inside save.verbose, but don't know how to fix this.
save.verbose <- function(..., file) {
cat("save.verbose:", file, "\n")
save(..., file=file)
}
foo <- function(x) { y <- x; save.verbose('y', file='foo.rda') }; foo(1)
save.verbose: foo.rda Error in save(..., file = file) : object 'y' not found Any suggestion how to fix this? Thank you for your time, Vadim P.S. I have a nagging feeling that I've already asked this question but I am not able to find any trace of it in the archives. My apologiesif this is so. [[alternative HTML version deleted]]
