Beginner. I use it frequently as a calculator. I used R on one large project on empirical likelihood for survey data.
SAS is my main tool.
I am a Principal Sampling Statistician with American Institutes for Research (AIR). I am retired from the federal government, having worked for the Bureau of Labor Statistics, the National Center for Ed. Statistics, and the Bur. of Transport. Stat.
