Hello,
I had expected that the following should work

What do I do wrong?
Misunderstand what 'apply' does perhaps?
It applies your function to columns (the '2') of the matrix, and so

Hi,
This should do what you are looking for:
x - matrix(1:10, byrow = TRUE, nrow = 2)
mapply(function(x1, x2) x1+x2, x[1, ], x[2, ])
But have also a look at colSums and colMeans

Hallo Thomas
Thank you for your answer, even I am not sure how to do it in R (or maybe at
all). My mathematics background is only faint so I drop the first possibility which
is for me rather cryptic.
Does your second suggestion mean:
1: compute random variable y -
Go download R version 1.8.1 (or later if available). They fixed
something with memory management from 1.8.0 to 1.8.1 which helped me out
of the exact same problem. I think it has to do with memory
fragmentation; R cannot find any chunk big enough for even a small
vector after some time.

Hello,
How do I get plot.survfit to draw a survival curve with prespecified time periods, say
1 month, 2, months, 3 months, 6 months, 1 year, 2 years etc) instead of the individual
times of all events?

Hi all,
I am a relatively new R user... trying to put error bars (from SD values) on my data
represented with barplot(). But I can't find any function or instruction to do so.
Is there an easier way to do this than using segments() as I saw in an example in the
R reference manual ? Then, can I

I am trying to import data to R. The programm always responds with:

Yes, you are interpreting the second suggestion exactly correctly,
apart from concern for possible correlations among x1,x2,x3.
If one can treat them as independent, I would do exactly as you
show: generate a vector of, say, n = 1 simulated draws from
x1, another vector of the same
Florian -
One thing to *try* would be: work from the R
command line and set the parameter nlines in
read.table() to one less than the number of
lines of data in the file. If this works, then
you can at least read in all but the last line.
I suspect something like a missing newline

It means the final line is incomplete, and you should complete it!

Dear All,
Ulric Lund and me are developing a new package called 'circular' that as
soon as possible will substitute 'CircStats' package.

I kindly ask everybody is using CircStats to check this new package

Using Sweave in the tools library (R version 1.8.0: sorry i havent

i have this:

if(exists(x))

This is the standard problem with if ... else: that will not work at the
command line either. Use braces like
if(exists(x)) {
plot(x,x)
} else {
plot(1,1,type=n)
text(1,1,data not available.\n)
}
which should do the trick.
