Hi! I would like to manipulate the actual argument names inside the
function. For example, I would like to do the following type of things:
***Splus session.
> foo <- rnorm(100)
> tmp.func(foo)
"foo.tmp" is generated!
***tmp.func definition.
tmp.func <- function(x)
{
# I would like to get the actual name of the object x here.
# Suppose I got somehow, the name of the object as x.name as a charcter string.
#
tmp <- eval(parse(text=paste(x.name, ".tmp<-x^2", sep="")))
assign(paste(x.name,".tmp",sep=""), tmp, frame=0)
cat(paste(x.name,".tmp is generated!\n",sep=""))
}
As a result of this operation, I would like to create foo.tmp in the
current Splus objects directory as a side effect.
I would appreciate your help!
Best wishes,
