memory problems
Hi
I'm computing a bca interval using bca.ci from the boot package.

> bca.ci(blm8901,index=29)
Error: cannot allocate vector of size 456729 Kb
However my machine has 2GB of memory and without R running I only have
112M of memory used.
Is there something

Hi
I have a list with several data.frames, all with the same number of
colunms but different number of rows, and I'd like to transform this
list into a single dataframe. I need to mimic an rbind of all dataframes

How to organize/develop an R function
Hi
Maybe this is not an issue about R. It's probably a programming issue
and I am not a developer at all. Anyway my main developing activities
are in R and that's where I have difficulties.
When I develop a function or group of functions I lose eternities with
the objects attributes and classes. I do a lot of object manipulation
(lists to arrays, factors to numeric vectors, etc, etc) so

New highlighting for NEdit 5.3
Hi,
I've just put together a new R syntax highlighting file for Nedit 5.3.

You can download the file here:

Classes implemented in R and packages
Hi
I'm writing some functions and I want to use some classes and related
ploting methods.
I want to know if there is a list of classes implemented in R and R
packages. I want to be shure that I'm not going to implement a class
with the same name as in other package.

NEdit Highligth patterns for R
Hi
I've just submitted to the NEdit development team a R highligth patterns
for NEdit (www.nedit.org).
NEdit is a text editor for LINUX which I use to write small R functions.
In my opinion is a very good tool for small scripts, maybe for huge
projects is not the best.
I'm attaching the R-5.1.pats file so you can try it.
As usual contributions and comments are welcome.

How to use complicated FUN in apply ?
Hi everyone
I'm trying to use
sigma2.mat<-apply(ri.mat,2,'-n/2*log(sum(ri.mat^2)/n)')

Is it wrong to use that kind of FUN in apply ? or am I doing something
wrong ?!

Excluding rows from a matrix
Hi
I have a matrix (4 x 950) and I want to remove 3 rows, where the values
from the first column are 713, 714 and 715. I can select the rows, one
by one, with
mat[mat$first==713,]
mat[mat$first==714,]
...
but I'm unable to (i) select the 3 rows at once, (ii) select the matrix
excluding those rows.
How can I do it ?

Error handling
Hi
I wrote a function implementing an algoritm for simulation of spatial
sampling plans (using geoR).
I'm using a range of parameters to perform several simulation and
sometimes this parameters create function errors wich cause the algoritm
to stop.
How can I avoid this ?
Below there's a small example that I made to study the problem but I was
not able to solve it. I've tried
