I can't reproduce that error. For me it works fine. What version of
R and gsubfn are you using? I switched to a French locale just to
be sure. I tried pasting it into an R session and also sourcing
it but both worked fine for me.

Dear R-list users,
I am trying to do simulation of survival data to
enable it to run under frailty option. Below is the
function a that I am using. My questions are:
1. How do I modify it to get bigger (hopefully
significant) value of Variance of random effect?
2. What changes do I have to make

Just wanted to say thanks very much. I used Chuck's 2nd idea as I found it the
easiest to understand as I'm still finding me feet with R. Just for reference
for anyone else, fn[1] and fn[5] actually pasted and gave the values at the
whiskers (~1.5 IQR) so replaced them with a max and min
Your example is a vector of strings not a string with mulitple lines.
To turn it into a string with mulitple lines use paste:
gsubfn('[][^]*[]', f, paste(Lines, collapse = \n))
If you want to break up the output to create a vector
of strings rather than a single multi-line string see
?strsplit
Hi All,
I'm new to R from a C and Octave/Matlab background. I am trying to
construct some classes in R to which I want to attach pieces of data.
First, is attr(obj, 'member name') - data the accepted way of doing
this?
Second, having attached member data with attr is there anything wrong

You may wish to provide brief commented source code: that would be most helpful
for people referring to it in the archives.
Many thanks and best wishes,

Hi...
I have to use R to find out the 90% confidence-interval for the sensitivity
and specificity of the following diagnostic test:
A particular diagnostic test for multiple sclerosis was conducted on 20 MS
patients and 20 healthy subjects, 6 MS patients were classified as healthy
and 8 healthy
Hm... sounds like a homework problem to me...
Maybe start by figuring out how to do it without R -
what's the approach, and how would you calculate it?
Then search R help for the possible key words you
came up with.

Dear Johann and Gabor,
It's what amounts to large datasets. There are hundreds of datasets R
can't handle, probably thousands or more. I noticed on my computer
(which is nothing more that an average PC) that R breaks down after 250
MB of memory. I also note that SPSS breaks down, Matlab, etc.
