Announcing pqR - a faster version of R
I have released a new, faster, version of R, which I call pqR (for
"pretty quick" R), based on R-2.15.0. Among many other improvements,
pqR supports automatic use of multiple cores to perform numerical
computations in parallel with other numerical computations, and with
the interpretive thread. It also implements a true reference counting
scheme to reduce the amount of unnecessary

Dear R helpers
I have some variables say ABC, DEF, PQR, LMN and XYZ. I am choosing any three varaibles at random at a time for my analysis and name these files as input1.csv, input2.csv and input3.csv. So if I choose variables say ABC, DEF and PQR, I am passing the specifications of these variables to input1.csv, input2.csv and input3.csv respectively.
This means in another case even if I

Using R to format a file using a server (PDB to PQR file)
I am trying to write a program that uses R and takes a pdb file, and converts
it to a pqr file. This task is simple generally, using the website,
http://pdb2pqr-1.wustl.edu/pdb2pqr/. How do you use R to input a pdb file
(that is on hand) into the upload pdb file input, and run the website and
give the return file to be a pqr file. Thanks for your help.

Very simple traffic shaping script for H.323

192.168.16.4. A Linux firewall NATs an external IP Address to this
internal address and I have appropriate SNAT and DNAT rules that work.
The NAT and connection tracking rules all work
