# How many different statistics packages use GPL (Graphical Programming Language)?

QUESTION: How many different statistics packages use GPL?

BACKGROUND: Most of what I am finding regarding GPL (Graphical Programming Language) is in relation to SPSS. While the literature I've seen indicates GPL was created to produce a cross-platform syntax for graphics, I can't seem to find references indicating that Minitab, R or STATA use GPL as one means of producing graphics.

While I am learning GPL because vanilla SPSS produces wretched graphics, my learning process would be psychically more easy to endure if I knew GPL was really more widely used.

• Can you explain what is GPL? – kjetil b halvorsen Dec 16 '17 at 20:56
• Thanks! I didn't realize that it could also be confused for the more common acronym of General Purpose License. – rabidotter Dec 16 '17 at 21:03
• GPL implements Leland Wilkinson's "grammar of graphics". R has an implementation in the package ggplot2, there are probably others, under differing names. – kjetil b halvorsen Dec 16 '17 at 22:48
