Hi, for your cor() command you will want to specify the "use" argument as

Dear Erin,
What you characterize as "snaky" might also be called bimodal and
short-tailed. Try, e.g., plot(density(residuals(dog1.aov))) to see the
bimodality more clearly. A Box-Cox transformation can correct skewness, but
won't help here.

Others have shown ways to remove your sample from the population, but this may
be doing things the long way. If you just want several samples from the same
population without overlap between any of the samples, just take one sample of
size equal to the sum of the individual sample sizes, random
Try this:

Hi Gabor,
it works! Thank you very much! But I still don't understand the difference

Dear all,
I just started to use the snow package to send multiple jobs on our cluster
using MPI and the Rpmi package as the communication method.
However, the Rmpi package have been behaving strangely. When I try to detach
the Rmpi package I get the following error message:

You could also look at littler
Then you could use, under Linux,
#!PTHTOR/r
x <- read.csv(...)
lm(...)

Hi there,
I know, this question is not directly an R-help question but probably someone
can give me a hint how to deal with the following problem.
I have a vector with file/folder names and want to filter for all entries which
have 6 numbers in a row and nothing else.
folders <- c("folder1
They are obviously growing desperate - I have now been asked to write

Dear Ben,
It seems clear that the problem is in loading the tcltk package. To confirm
that, does library(tcltk) fail?
I'm not very knowledgeable about Mac OS X. I do have a MacBook, with OS X
10.5, however, and encountered no problems installing and running the Rcmdr
package. Have you seen the R
Hi Uwe,
Thanks for the reply.
I already tried that a couple of weeks ago, with the exactly the same
arguments you posted. So far no reply from the author.
I going to try again.

Where myFirstScript.R as the following line

You could also use a editor like emacs with the ess-mode where one buffer can
be your script with a live R session in a second buffer.
Good luck

Since I'm a SAS programmer, I'm used to creating command files in an editor for

internet and before headbanging against the wall would like to try asking
for your help.
As many others, i am haveing problems loading the Rcmdr package with Macbook

I would suggest sowas (Douglas Maraun) or wmtsa (Percival and Walden).
I don't know for sure but both of these probably rely on Rwave. I
like both of the packages mentioned it just depends on what you want
to do- wmtsa will do DWT and CWT + a lot more, and sowas is for
testing hypotheses and wav
Since SVG has a lot of elements, Firefox is still under development to
support different elements in SVG; see:

Currently animations won't work under Firefox 3.0.4, and all the rest
can be viewed using Firefox 3.0.4.

vec <- c("a", "b", "c")
paste(vec, collapse = "")
I hope it helps.
