R is a free software and programming language for statisticians

I have been a big fan of R around 20 years. I started using R in 2002 when I was a graduate student in Chiba Univ. Before using R, I used S-PLUS around 2000~2002.

R studio makes R more user friendly and powerful

I have been enjoying R studio around 10 years. I started using R studio when I got my faculty job at NCU in 2011. My main motivation of using R studio is its enhanced environment for R programming.

CRAN (Comprehensive R Archive Network) is a repository of R packages made by users.

I submitted my first R package in CRAN on 2012/4/6 (the compound.Cox package, Version 1.0). Since then, I have been maintaining five R packages.
