And what would be the authority that supplies such a certificate? R is not the proprietary property of a company or person, so I don't think a body exists that could supply such an authoritative email. What does (or should) exist are the comments in the source files explaining the license terms, and this is echoed in the banner message on startup. I'm sure if you asked very nicely you could get a letter from someone held in high esteem by the R community - some professor at an ancient university perhaps - stating their belief that you can use R for your company in accordance with the licenses. But that would just be repeating what you've already heard here. The licensing is with the code, and clearly stated. Other, larger companies use R extensively - see this recent blog entry: http://blog.revolutionanalytics.com/2014/05/companies-using-r-in-2014.html Note in particular the banner when R starts: "ABSOLUTELY NO WARRANTY" - which means if a bug in R makes one of your gas processing plants explode, there's probably nobody to sue - but if you read the small print on proprietary software licenses you'll probably find similar terms anyway. R puts it out there in block capitals every time.
