-- BBands [BBands@xxxxxxxxxxxxxxxxxx] : > Is there a way to pass arguments to an R script? > Something like: source('script.R', arg1, arg2) Dirk would know this better, but to pass *command line* arguments, ?commandArgs > commandArgs() [1] "C:\\Program Files\\R\\rw1091\\bin\\Rgui.exe" and there's quite a bit in the R-help archives about this However it seem's you asking about passing 'extra' arguments to source() *in the GUI* Arguments to what? Where are they being plugged in, assuming you have them? I fiddled with ideas like mysource<- function(x,...) source(x,...) with no immediate success
