'closure' (was "stats:: spline's method could not be monoH.FC")

Hi Richard: I didn't say it was and didn't mean to imply it.  All I said
is that it was an example of where "not understanding environments"  can
lead
to errors that won't be understood by the person experiencing them. It
just so happens that the use of  "environment(f) <- " can lead to a
solution but there
are other solutions and it was not my intention to talk about the various
solutions. Only that it can be helpful if one understands the notion of
environments in R.

That example is NOT an example of "messing around with environments."

Hi Abby: I agree with you because below is a perfect example of where

not understanding environments causes a somewhat

mysterious problem. Chuck Berry explains it in a follow up  email.

If you want to mess around with the environment of a
function, then you need to understand this stuff, but you probably
shouldn't do that.

What exactly do you mean?

Are you implying that a user should not use environments?
In which case, I would disagree.
