If I remember correctly --- haven't used Splus for decades --- this is a
difference
between Splus and R.
In R the output of a function is returned *invisibly* if that function
is called
from within another function. And source() is one such other function.
So if you have a script, say "melvin" with the single line:
sin(42)
and in R you execute
source("melvin")
you will see no output. If in another script, say "clyde" you have the
single line
print(sin(42))
and in R you execute
source("clyde")
you will see
[1] -0.9165215
In Splus, IIRC, the print() call is unnecessary. I.e. you would get the
same
result by sourcing "melvin" and "clyde".
Current Splus users may correct me if I am wrong about this.
