[R] Problem w/ source

[Peter Muhlberger]

I'm trying to use the source command to run commands from a file.  For
instance:  source("do.R"), where do.R is a file in the same directory in
which I am running R.

The contents of do.R are:

ls()
print("hello")
sum(y1)
mean(y1)


After  source("do.R"), all I see is:

> source("do.R")
[1] "hello"


I'm using the X11 version of R for Mac OS X (downloadable binary).  Does
anyone know how to get source to work?

Thanks!

Peter
