Indeed. I really like working with r scripts. And littler by Horner and Eddelbuettel is faster than Rscript -- see eg the scripts tests/timing.sh and tests/timing2.sh in the SVN archive / littler tarballs (and the results below for illustration). We should still appreciate it you could finally acknowledge existence of littler it in the R / Rscript documentation. You are not doing users any service by pretending it doesn't exist. That said, we are not (yet ?) building r for Windows, and I appreciate that Rscript is available there. Maintenance and use of R will be easier with a consistent set of tools. This is a good move.
