Hi -
I'm running R 1.8.1 (compiled from source) on Mac OS X 10.3 (Panther). I
find that, if Apple's X11 application is not running, Sweave gives an
error when it wants to create a pdf or eps figure. E.g., in the package's
own example-1.Snw file a boxplot is created at chunk 2:

Dear all,
How can I control the length of tick marks in grid.xaxis and grid.yaxis
(package grid) ?
Best regards,
Renaud

Hello all,
I'm new to R (and the S language in general) so go easy on me if this is really simple.
Given a data.frame df which looks like this:
f1 f2 f3 f4 c1 c2
1 y y a b 10 20
2 n y b a 20
Is there a limit to this? I'm working with a .Rdata file about 190 Mgs in
size and R won't open it...thanks...mj

Thanks. I changed TMPDIR and TMP to c:\Temp. But "Rcmd build" failed
again. This time the problem is the path of "make". Although
I put C:\bin in front of path but "build" went to $R_home/bin to find
"make". "Rcmd make" was succesful before. I think the path is still not
correct.

Hi Erin,
CLARIFICATION: I am looking for function which can calculate distances
between
rows in two different matrices (not in the same matrix as dist).
Of course I can get the desired result by using rbind() and fiddling with
indices of the result, which I already did,
but I wonder if there is

Hi Ryszard!
There is a dist function in R.
It's in the mva package.
You can set the kind of distance that you want.
Thanks,

You might get more useful answers if you gave more information about
exactly what you did. My wild guess is that you are sourcing a file (with
the function source()), the first line of which is the QQQ<-..., and the
second line of which has a syntax error.
One of the nice things about R is tha
I have this line at the start of my code file.

And I get an error ...

What does this error mean and how can I correct it?

I would recommend reading the following: Dietterich, T. G., (1998).

Learning Algorithms. Neural Computation, 10 (7) 1895-1924.

The issues in comparing methods are
One relatively easy way would be to construct some dummy data with the
appropriate names and formula, use lm() to construct the model object, and
then change the coefficients in the model object to be what you want (e.g.,
by fit$coefficients[2] <- 0.79). This should then work with
predict().
Dear Professor Ripley,
Sorry I didn't get what the manual says. I read readme.package and also R

guess is right. The TMPDIR was set to c:\Documents

Leave-one-out is very inaccurate for some methods, notably trees, but fine
for some others (e.g. LDA) if used with a good measure of accuracy.
Hint: there is a very large literature on this, so read any good book on
classification to find out what is known.

Is there a function in R (similar to dist) which would calculate
distances between rows in two different matrices ?

Hi
what would you recommend to compare classification methods such as LDA,
classification trees (rpart), bagging, SVM, etc:
10-fold cv (as in Ripley p. 346f)
or
leaving-one-out (as e.g. implemented in LDA)?
my data-set is not that huge (roughly 200 entries)
many thanks for a hint

Or another way besides predict(

This is possible. It is not an interactive process, though--R does not have
that capability with heatmap. See ?cutree which you can apply to gclus to
get the indices of genes in clusters that you define based on the dendrogram
and then use these genes as input to heatmap (this will amount
