Dear helpeRs,
I have some png files in the inst/extdata directory of a package (e.g.,
man.png), and I want to provide character strings containing the paths to
these files; of course, these path strings have to depend on the individual
installation. So far, I have written a function that - if
Dear expeRts,
I have run some simulations under R 2.15.1 on a Mac, and I have rerun a
sample of them under R 3.0.1 on Windows (and also for comparison under
R2.14.1 on Windows). For most cases, I get exactly the same results in
all three runs. However, for those cases that depend on principal
Dear helpeRs,
I would like to include generation of a potentially large number of
plots, and modify the ask settings using the devAskNewPage function, and
return it back to its original state afterwards.
It is not unlikely that the user escapes from the long list of plots
before reaching the

Thanks to both of you, you are probably right that memory is the limiting
factor. I have no knowledge about the available memory on the lab machines,
but I will find out and make sure that this is the explanation.

Dear R-helpers,
I am puzzled by the following observation:
On my home dual core Windows desktop computer, I am used to running two R
sessions in parallel. These do very well in using the full CPU of the
computer (half each) and don't seem to slow each other down.
Today I have started some large

Dear UseRs,
I just learnt that the number of columns of a data frame is not always what
I thought it to be, and I wonder where I should have learnt about this.
Consider the following example:
dat - data.frame(X1=1:10, X2=LETTERS[1:10])
ncol(dat) ## evaluates to 2 (of course)
dat$X1poly
an object that is considered a
model.matrix.

Birgit,
not knowing your data, I would recommend R-package mice or function
aregImpute from R-package Hmisc as good multi-purpose tools.

relaimpo does work with a (non-robust) linear model, i.e. calculations in
