reading non-existent files
Dear R-experts
I would like to read all files from a directory, the files have names
"myname0001.txt" etc. I paste the directory plus file names and
use "read.delim()".
My problem is that some file names are missing, so I get an error
and my program stops.
Is there a way to check for a null pointer analogous to C, so that
I can simply skip non-existent filenames?
Please do

FW: [Fwd: Re: [S] Exact p-values]
Dear all
Just for fun, I have just downloaded the paper mentioned below and checked
it with R-1.6.1.
Everything is ok with exception of Table 2b, where I get always 1 instead of
0.5:
> pbinom(1e15,2e15,0.5)
[1] 1
Which value should be correct?
Best regards

mapping of colornames into hsv: half way done
Ok,
now we have the mapping of color names to color codes (see below) and
conversion to rgb (something like Ben Bolker's function), but how to convert
rgb to hsv?
Thanks to Brian Ripley, Peter Dalgaard and Ben Bolker

Dear all
I apologize for cross-posting, but first it is accepted custom to
thank the repliers and give a summary, and second I have still
the feeling that this problem might be a general statistical problem
and not necessarily related to microarrays only, but I might be wrong.

Plotting color.legend() outside of plot region
Dear List,
I am trying to plot a color.legend() in the right outer margin of my device region. I have read multiple threads on the subject and still can't get it right. I have stolen an example from one of the threads to demonstrate my problem. I have extended the outer margin using par(oma()), and have used par(xpd=NA) to tell it to plot in the device region. I can get the legend to plot

replace negative numbers by smallest positive value in matrix
Hi Group,
I have a matrix, and I would like to replace numbers less than 0 by
the smallest minimum number. Below is an
small matrix, and the loop I used. I would like to get suggestions on
the "R way" to do this.
Thanks,

Reference to dataframe and contents
This is probably easy for experienced users but I could not find a solution.
I have several R scripts that process several columns of a dataframe
(several dataframes and columns actually, but simplified for my question).
References such as:
myDF$myCol
are all over. I like to automate this for other dataframes and columns by
defining a reference only once in the beginning of the script.

Multiple symbols per single line in a legend
Hello everybody,
Is it possible to coax legend() into displaying more than one simbol per
line in legend? I have a graph like the one attached to this mail; I would
like to reorganize the legend in such a way that the duplicate text would be
omitted, i.e., the first line would read <square> <triangledown> "increasing
frequency" and the second one would read <circle>

RE: Comparison of correlation coefficients - Details
Dear Ioannis
Thank you very much for pointing me to meta-analysis. Although it
may not solve my problem with the normalization, it gives me some
other options to display the different correlation coefficients.
One possibility is the use of Funnel plots, which are even available
in library(rmeta). Another possibility is the use of forest-plots,
as implemented in rmeta as metaplot. Sorrowly,

heatmap.2 problem

I'm trying to generate a simple heatmap that has each row and column
