I don't have a question, just a point of information I wanted to share.

When I have an infinite value in the first argument to loess.smooth() it
consistently crashes my S-PLUS session.  I'm using S-PLUS 2000 Professional
Release 2 for Windows NT.

For example, this statement yields a warning message, but doesn't crash my
session.
loess.smooth(1:10, c(Inf, 2:10))

But these two statements give me the following application error.
     loess.smooth(c(Inf, 2:10), 1:10)
     loess.smooth(c(-Inf, 2:10), 1:10)
     The instruction at "0x..." reference memory at "0x...".
     The memory could not be "read".
