Not sure what domain you're in, but here's the view from mine...

SAS is extremely common in pharma companies. Basically, any company that has anything to do with a clinical drug trial will be using SAS.

In the basic research / tool development parts of the biotech industry, R is common as well. Today, basically every biotech company has some kind of "data science" component (though they won't necessarily have adopted that buzzword).

Either way, in my view this is a far more specific and valuable skill than "HTML programmer".
