A question on memory size
Hi,
I am using a note book computer to do simulation. Even I added a commend
line in the shortcut on my desktop for R. I still get a message saying
reached total memory allocation of 502 Mb. Any suggestions will be welcome.

R for Windows crash on new laptop - corrected script
I realized that the script I included in my original post (see below)
was written for an older version of rmetasim and will not work with the
current version. The only change that need be made to get my script to
run with the latest release of rmetasim is to change the command
'simulate.landscape()' to 'sim.landscape()'. My apologies to anyone who
tried to use my script and

64 bit R for Windows
I am assisting in the purchase of 64-bit Windows XP system for researchers who run R. These systems will have AMD Opteron processors and at least 4GB of RAM. I'd appreciate advice on whether there is a working version of R that can take full advantage of such systems.

Area of overlap between polygon and circle
R-listers,
Given a polygon and a circle defined by its center coordinates and a
radius, I would like to calculate the area of overlap. I know that I
can create a polygon from the circle and then use available packages to
get the area of the intersection. However, because the polygon is of a
fixed size and I will be doing this for circles of varying sizes, I'm
concerned about

Single vs. dual CPUs
I've posted this earlier and have not heard much so far. I'd really appreciate any guidance on this as we are about to order new hardware.
We are buying Dell workstations with Red Hat Linux and 64-bit Xeon CPUs to run R. We could add a second processor to each system, or buy slightly faster single CPU systems. Is it possible to make a generalized statement as to what kind of performance

Creating multiple copies of rows in data frames
ListeRs,
Within the last two months, I thought I saw mention of an R function
that would create a new data frame composed of duplicates or multiple
copies of rows of an input data frame given one or several columns of
values indicating how many times each row should be copied. As a simple
example, given a dataframe:
> in.df
x y
1 A 1
2 B 2
3 C 3

I have some spatial patterns of sardine eggs (presence /absence) over 50
years (270 surveys) and I'd like to quantify the patches and gaps to
determine how many patches (i.e. spawning areas) there were before the
fishery collapse (1951-1965) and during recovery (post 1985).

combining lists with same names with 'c'
I recently ran across an unexpected problem caused by combining lists
that contained elements of the same name. I naively thought that the
elements would get overwritten, but rather the "new" element gets added
with the same name. A simplified version is :
> my.list <- list(a = 1)
> new.list <- c(my.list, list(a = "a", b = "b"))
> new.list

use of step.gam (from package 'gam') and superassignment inside functions
Hello,
I am using the function step.gam() from the 'gam' package (header info
from library(help=gam) included below) and have come across some
behavior that I cannot understand. In short, I have written a function
that 1) creates a dataframe, 2) calls gam() to create a gam object, then
3) calls step.gam() to run stepwise selection on the output from gam().
When I do this, gam()

Vector searching and counting speed optimization
R-users,
I'm seeking any suggestions on optimizing some code for speed. Here's
the setup: the code below is part of a larger chunk that is calculating
Fst values across loci and alleles. This chunk is designed to calculate
the proportion ('p.a') of an allele ('a') at a locus in each population
('p') and the proportion of individuals heterozygous for that

meaning of lenwrk value in adapt function

In using the adapt function, I am getting the following warning:
Ifail=2, lenwrk was too small. -- fix adapt() !
Check the returned relerr! in: adapt(ndim = 2, lower = lower.limit,
upper = upper.limit, functn = pr.set,
Would someone explain what the 'lenwrk' value indicates in order to help
diagnose this issue.
Also, what are the possible codes for Ifail, so I can set

R for Windows crash on new laptop

Concerning reading of SAS-files

I'm trying to start a credibility estimation study with a coule of data
sets that are created for SAS. The data sets are saved as ".sas7bndx" and

I've tried reading them to R with the function 'read.xport' but this

Are there any other functions that one
