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)
}
