To Narendra;

I get the idea that this line of inquiry is designed to obfuscate R code and derivative works, which in turn I see as an effort to defeat the open source nature of the R movement. It at least violates the spirit of the various licenses under which R and the CRAN packaging policies are distributed.

I'm suggesting that those people who support an open source basis of R not continue to use Rhelp as a venue for an effort to undermine the openness of coding supported by R. If Bob disagrees with me, he is at liberty to correspond with you privately. I have no authority to enforce such advice, and anyone is free to opine on the ethics and legality of this proposed effort.
