Thanks, Michael. I hadn't heard of this product before.
There are many reasons that people who do data analysis for a living
choose a tool that was designed for that purpose. Perl is simply not
in that product space. As just one example, the R environment has
become a standard in the statistics community because it provides both
a powerful programming language and excellent graphics. Creating heat
maps is simple in R.
Try it yourself. It'll take you about 5 minutes.
1. Install R: http://www.r-project.org/
2. Copy and paste the example code from the bottom of this page into
the R console: http://sekhon.berkeley.edu/stats/html/heatmap.html
(there are several distinct examples there--if you copy the code line
by line you'll see how it works.)
