describe below is the one from 3 dimensional vector geometry. You can
get that one in R in a few different packages, but it's not really used
much in statistics, so it's not in base R. (It's called xprod in RFOC
and RSEIS, extprod3d in geometry.)

is a partially
blinking one. Optionally the current solid cursor or a fully blinking
one can be used.
Duncan Murdoch
For my last exam she used R in a Dosbox as workaround, but encountered other
problems, esp. with scrolling. So: Is it possible to change the cursor
type/behavior in R-Console?
She uses
-values are probably associated
with larger departures from the null. But the p-value is not a good way
to estimate that distance. Use a parameter estimate instead.
Duncan Murdoch
Essentially, a p-value is as real as your
assumptions. In that way I can understand what Robert wants to say

Even if I dont evaluate the function tmp[[1]] before i.e I do
rm(list=ls())
f - function(y) function() y
tmp - vector(list, 5)
for (i in 1:5) tmp[[i]] - f(i)
z - f(6)
tmp[[1]]() # it still returns 5; it should return 6 ideally right ???
See above.

I would think the first step would be to ask Mr. Quick what's wrong.

read them, substitute for the default title line, and write them back.
If you don't want informative help files, it's really not much work to

together enough information for predict() to work
properly. However, you can do predictions for many models just from
their definition, and you may have enough information to calculate
errors as well. But you'll need to program the formulas yourself.

Dunlap of Tibco has been making valuable contributions to S and S-PLUS

Would have acted more in a similar way.
(And if they do, I didn't know about it and would like to have been more
for the R-devel list. And he may not get much
sympathy there: R is an open source project, and developing ways to
hide code is not something that interests most of us.

don't know if you can specify the
output encoding; it won't help to do it in the document code chunks).
You also need to put the line
\usepackage[utf8]{inputenc}
into the document preamble, but it sounds as though Lyx has already done
that for you.
