[R] Problem with Perl script calling R function

I'm a student doing my masters thesis and trying to work with S-Net
version 1.0 (tool used for statistical analysis and visualizations of
internet traffic) that is written in R.

The problem is this: I have a perl script calling a function defined in an
R script that is located in a directly different from where the perl
script is. This gives the following error.

>>> echo
'read.flow("BLDemo.2000.03.08.h12.m30.35.tcppac.gz",type="tcppac")' |
/cab/ce/user/ramagopa/lib/bin/R --no-save --no-restore --quiet --slave
Error: couldn't find function "read.flow"
Execution halted

Platform details:
R-1.4.1 (I have to use this version because the version of SNet requires
only this).

Could someone help me out with this problem? Additionally, I'd really
appreciate it if someone can point me to an SNet mailing list; I haven't
found one on the web.
