I have an R script file that executes a second R script via:

source("../scripts/second_file.R")

That second file has the following lines:

myfiles <- list.files(".",pattern = "*.csv") 
...
rm(myfiles)

When I run the master R file I get:

> source("../scripts/second_file.R")
Error in file.remove(myfiles) : object 'myfiles' not found

and the program aborts.

I think this has something to do with the environment. I looked at ?rm() pages but less than illuminating. I figure I have to give it a position argument, but not sure which.
