Hi,

I guess it's a stupid question, but I don't get it :-(

I wrote an R script, which creates heatmaps out of xls files. I am calling this R script with a Perl system call and pass over all the arguments. This all works fine.

Now I wanted to make the R script less confusing by writing different functions in the R script, for example:

args <- commandArgs(TRUE)

parsexls <- function(filepath)
{ data <- read.xls(...)
assign("data", data, globalenv()) }

reorder <- function(var)
{ data <- data[order...]
assign("data", data, globalenv()) }

When I want to call the functions with

parsexls(args[1])
reorder(args[2])

nothing happens.

But when I place the parsexls(args[1]) in the script between the two functions shown above, the file is parsed correctly! The reorder(args[2]) seems never to be read.

Any ideas what I am doing wrong?
