R help - Jul 2003 - Problem w/ source

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!

Works perfectly, but no automatic print() is executed as the default 
when sourcing. When you want the other objects to be printed either use
   print(ls())
   print(sum(y1))
   ...
or use
   source("do.R", print.eval = TRUE)
as described in ?source.

You probably want 

source("do.R", echo = TRUE)

or maybe not; see ?source.

Well, we feel that source does work the way that it is documented to
work.  Please read the documentation and notice that the entire file
is evaluated as one step in the read-eval-print loop.  If you want to
print the results of individual function calls you will need to change
your script to

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

Thanks to everyone for their suggestions on getting source to print!  It
seems not everyone was aware of a couple options that gets source to print
out everything.  I'm now using the following command:

source("do.R", print.eval=TRUE, echo=TRUE)
