[R] Legality of copying from Splus.

A few days ago, I sent a question to the r-help list enquiring
about the

		        *** LEGALITY ***

of porting a function from Splus into R.  As a particular example,
I referred to error.bar.

Several people posted code for various versions of error.bar which
they had written, but that was NOT WHAT I WAS ASKING FOR/ABOUT!!!

[Can't anybody ***read*** these days?]

I asked:  IS IT LEGAL/ETHICAL to take a copy of an Splus function
(written in raw S), ***such as*** error.bar, and make it into an R
function?  Is it OK to do this for one's own personal use?  What
about making such a function available to other R users (who may not
have Splus licenses)?

Would the big guns from the R community please comment on this?
