I hold a M.S. in Pure Math and I have been working as a community college instructor for a few years. I recently completed a graduate certificate in statistics (15 graduate credit hours - Mathematical Statistics I and II, Linear Statistical Model, Machine Learning I and II) and I'm interested in becoming a statistician. Now, I have been using "R" for my entire statistic program, but as I am doing job search on USAJOBS and Indeed I found that a number of the positions require both SAS and SQL (especially on government jobs, I am a US Army Veteran and I'm hoping to work for the Feds as I can carry my service years into the job), so my question is: Should I continue to learn more to master "R"? Or should I go ahead and focus on learning SAS and SQL?

Any comments are appreicated, thank you in advance!
