John C. Dvorak, PC Magazine, pg. 73, March 28, 1989:
"Genuinely Interesting Software Dept.: Here's one of those nicely done packages that you see once in a blue moon. Grad student Bob Simmons spent 3 years developing three inexpensive but quite elaborate systems: CoPlot, a scientific graphics package; CoDraw, an excellent technical drawing package; and CoStat, a superb statistics package. If you're in the market for some slick scientific/engineering software, then get these systems. ... Don't let the low price fool you; this is excellent software."
Samuel Ing., M.D. International Journal of Biomedical Computing, 32 (1993) 81-82:
"This set of programs constitutes a very cost effective and functional tool for the scientific researcher not only in the analysis of data but also in the preparation of scientific publications."
Tony Barcellos, Sacra Blue (Sacramento PC Users Group), pgs. 57-59, January 1991:
"Overall, the program is extremely impressive. The documentation is readable and extensive. The program requirements are incredibly modest for a package of such power. In flexibility and control of detail, CoPlot is hard to beat."
