Subject: [R] New Perl module Statistics::R
I have released the new module Statistics::R and need some feedback of it's
This will permit the control of the the R (R-project) interpreter through
Perl in different architectures and OS.
You can for example, start only one instance of the R interpreter and have
different Perl process accessing it. What will save the initiation time of R
Soo, I will appreciate if some one can test it in different OS. Tested with
Win32 and Linux.
Thanks in advance.
