Francisco, I had exactly the same question a few days ago. Try the following: z<-function(x) { xName <- deparse(substitute(x)) cat(xName) cat("The parameter name was ",xName,"\n")
} Let me know if this works. n.b. the \n in the cat function is a signal to print the next piece of data on the next line.

Here is a simplistic example of what I would like to obtain: myfunction= function(name) { print(paste("The parameter name was",unknownFunction(name)) } myfunction(myobject) [1] "The parameter name was myobject" Thanks Francisco ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html [[alternative HTML version deleted]] ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
