Now I have different problem, awk doesn't have an erfc() function. I need to process a lot of data and produce graphs, sometimes this involves mathematical functions like erfc(). Maybe I'm trying to use awk beyond its intended purpose. I have used C and C++ in the past but I want to use a script instead. Perl seems to be a solution at the moment, but I still haven't found an erfc() function. I need to learn about Perl modules don't I?
Depending how much data, and how complex the analysis maybe R is the thing.
