Vadim et.al:

I do not care to comment one way or the other about R's "irregularities.' But I am puzzled by your statement that a "good C++ programmer is struggling with R." Why should they not struggle?! R is primarily a language for data analysis, statistics, and graphics. I do not understand why someone who is a C++ programmer would be expected to have the knowledge and experience to be a "data miner" and would not therefore struggle to deal with the statistical and data analysis issues that are deliberately at the heart of many of R's programming conventions.

Is there something here that I am missing, or is this yet another example of Frank Harrell's "instant brain surgeon" commentary?
