How to extract se(coef) from cph?
Hello,
I am modeling some survival data wih cph (Design). I have modeled a predictor
which showed non linear effect with restricted cubic splines. I would like to
retrieve the se(coef) for other, linear, predictors. This is just to make nice
LateX tables automatically. I have the coefficients with coef().
How do I do that?
Thanks,
David Biau.

aggregate, by, *apply
Dear R gurus,
I regularly come across a situation where I would like to apply a function to a subset of data in a dataframe, but I have not found an R function to facilitate exactly what I need. More specifically, I'd like my function to have a context of where the data it's analyzing came from. Here is an example:
### BEGIN ###
func<-function(x){
m<-median(x$x)
if(m > 2 &

Creating publication-quality plots for use in Microsoft Word
Hi everyone,
I am trying to make some publication-quality plots for use in Microsoft
Word, but I am having trouble creating high-quality plots that are supported
by Microsoft Word.
If I use the R plot function to create the figure, the lines are jagged, and
the picture is not of high quality (same with JPEG(), TIFF(), and PNG()
functions). I have tried using the Cairo package, but it distorts

I am a student, and need to use R a lot. But sometimes when I am working in

of the previliges.
Can the folder of Librabry of R, move to, for instance the personal folder, my
documents... then we can install any specified package?
Best regards,

writing R extension
I'd like to develop a simple library in R in which to save my
particular functions.
I have read the manual on "Writing R Extensions" but it's too
difficult. Someone could help me?
I want only save my personal function (recorded in R-code, not in C) in
"myLibrary" and I want to call it with:
>library (myLibrary).
After this, the functions should be available

Introduce a new function in a package?
R-help,
Sometimes I define functions I wish to have in any R session.
The obvious thing to do is copy-paste the code
The thing is that sometimes I don't know where I have the function
code.
My question is if somehow I could define a function and "introduce" it
(let's say 'base' package ) so that
could be used anytime I run a different R project.
Thank you in advance

multiple plots in single frame: 2 upper, 1 lower
Hi,
par(mfrow = c(2,2))
will create a 2x2 window that I can use to plot 4 diferent figures in:
[plot1 plot2]
[plot3 plot4]
But how can do 3 so that the bottom spans the width of the upper two:
[plot1 plot1]
[p l o t 3]
Is this possible in R?

this produces red-edged circles, but I want to fill in the circles.
can this be done? I checked '? plot' already but couldn't find what I was
looking for.

Getting JRI/rJava to work
Hello All
I am trying to get the JRI examples from rJava to work on Windows XP and

I have installed rJava from the Windows binary supplied. I compile and
run the example supplied (rtest.java) and get the results below. I do
not think the notes about a deprecated API are a problem. But
