predict.loess and NA/NaN values
...w to change it. So I'm asking the community: Is
there a way to fix this or do I have to code around it?
This is in R 2.11.1 (Linux), by the way.
Thanks in advance

invoking user-defined function
Dear list,
Can somebody tell me how to invoke user-defined functions from script
files during run-time?
Basically I have (almost) one function per script file.
I am thinking of something like
#include in C++
import in Java/Python
use in Perl
No, I don't need my functions every time R is started.
Neither I am thinking about writing building my functions into
packages.

change attributes of all data.frame elements
Hi,
I was wondering whether there was an easy way to change the attributes
of all elements in a data.frame (rather than looping through elements)?
Specifically, I would like to set the "dim" attributes to NULL
Thanks for any help,

Bizarre - R crashes on merge
Hi all,
I have a large data.frame, 1530 observation with 6 columns. I want to
merge a 7th column, a transformation of the response variable (hospital
admissions), namely
trans<-sqrt(copd$admissions+0.25)
trans<-data.frame(trans)
And now when I do
copd2<-merge(copd,trans)
(copd being my original data.frame), R either crashes or is taking an
extremely long time to do the computation. I

package for factor analysis
I have Windows XP Professional Version 2002 and the R-Version 2.1.1.
I want to do factor analysis with R.
In Google Search I find the reference to the RScaLAPACK-Package, but my
R-Version 2.1.1. told me that "RScaLAPACK is invalid package, bevor
2.0.0. installed" .
Which package can I take for factor analysis?

beamer overlays with Sweave?
This may be asking too much, but I'm wondering if anyone has a
solution (even a hack) for creating multiple (overlay) plots in an
Sweave file and post-processing the overlays in beamer appropriately.
For example, suppose I have a series of figure blocks in my .Rnw file:
<<plot1,fig=TRUE>>=
[stuff]
@
<<plot2,fig=TRUE>>=
[stuff]

Simple Missing cases Function
Dear all
I have written a function to perform a very simple but useful task which I
do regularly. It is designed to show how many values are missing from each
variable in a data.frame. In its current form it works but is slow because I
have used several loops to achieve this simple task.
Can anyone see a more efficient way to get the same results? Or is there

Using graphics straight from R into published articles
Hi,
I have been working with R for the past couple of years; analyzing data and
producing some graphics.
I was just wondering if people use graphics from R straight into articles or
are they always edited in some way; fonts, headers, axis, color etc? Using
photoshop or some other programs?
I would like to think it is possible, better and more profession to do it
all in R.

Is there any R function to get the indices of y for the elements of x, that

I know i can combine apply() and grep("^aab$", y) to do it. But is there any

Width of text displayed in R
All,
I think this is pretty basic but I couldn't find the answer in any
source.
I have just built my own R for Linux (amd 64). It runs well, but R
thinks that it only has 80 characters or so of screen width. I log on
with Putty to the box and can stretch it as large as I want.
Is there a simple way to tell R to use more screen width when
displaying?
