Dear colleagues,
if I import vegetation data (first row with column labels and first column

This is a known bug (PR #3234), only affects Win98.
The problem is the degree sign (or any nonstandard ASCII)
in your first line (7SALNIG°)
Mostly you can actually read these things in OK, but R crashes
on printing. I get round it sometimes using something like
dedegree - function(x) gsub(°,

its desired that name act on factors in the same way that names

Please, can you advice me how to compute an error, standard deviation or
another measure of variability of computed value.
I would like to do something like:
var(y) = some.function(var(x1),var(x2),var(x3))
for level F1 (2,3,...)
Let say I have some variables - x1, x2, x3 (two

On the cran package source page, to each package there are the reference manual in

But the nice title page are missing. During the package build and

Very briefly, I think of three ways to approximate the standard
deviation of y = f(x1,x2,x3).
(1) linearise f() and use the covariance matrix of [x1,x2,x3].
(2) simulate draws from the joint distribution of [x1,x2,x3],
then compute the sample std dev of resulting f()s.
(3)
I don't have Windows 98 to test it out but assuming
that it causes read.table to crash but not readLines,
you could try doing the preprocessing in R itself using
Simon's dedegree like follows to see if it works:

Hi all,
I discovered this problem when trying to use princomp in package:mva
when a column (and row) in my matrix was all zeros and I set cor = TRUE,
thus division by 0. Doing so hangs R, never to return. I have to shut
down Rterm in the Task Manager and lose all work from the current image.

Not really much hope here, but
1) If you have fast discs, try increasing --max-mem-size to more than your
RAM, and
2) Try compiling up R-devel (see the FAQ for where to get it) as it has
a potentially better memory allocator.
I supect though that your problem is too big for R on 32-bit

You might take a set of classified data, say Fisher's irises, and treat
the classification as initially unknown.

Thank you all! I did it, and it worked just fine. In the last week I've been
