expand gridded matrix to higher resolution
You probably ought to be using the raster package. See the CRAN Spatial Task View.

reshaping column items into rows per unique ID
I believe you need to spend time with an R tutorial or two: a data frame
(presumably the "table" data structure you describe) can *not* contain
"blanks" -- all columns must be the same length, which means NA's are
filled in as needed.
Also, 8e^5 * 7e^4 = 5.6e^10, which almost certainly will not fit into any
local version of R (maybe it would in some server version --

Matrix problem to extract animal associations
Dear List,
I have been trying to extract associations from a matrix whereby individual locations are within a certain distance threshold from one another.
I have been able to extract those individuals where there is 'no interaction' (i.e. where these individuals are not within a specified distance threshold from another individual) and give these individuals a unique Group ID containing

assign NA to rows by test on multiple columns of a data frame
...well, I don't think this is exactly the expected result (see my post)
to be noted that the columns affected should be "A" and "B"
thanks for the help

problem with svyglm()
Hello,
I'm trying to use the function svyglm in the library survey.
I create a data survey object:
data_svy<- svydesign(id=~PSU, strata=~sample_domain,
weights=~sample_weight, data=data, nest=TRUE)
and I try to use svyglm() with little success:
R<-svyglm(data_svy[,4]~(data_svy[,iCol]==listModality[[iVar]]

assign NA to rows by test on multiple columns of a data frame
Hello,
Try the following.

How to override coerion error in 'scan'
I am using 'read.csv' in V2.0.1 to read in a CSV file with the
colClasses option and am getting an error from 'scan' when it encounters

Hi Allaisone,
I took a slightly different approach but you might find this either as or
more useful than your approach, or at least a start on the path to a
solution you need.

variadic functions on X86_64 should (conditionally) save XMM regs even if -no-implicit-float
Specifying -no-implicit-float prevents LLVM from using non-GPR registers for purely integer operations. This is useful for operating systems (such as Wind River's VxWorks) that support tasks that do not save all registers on context switch.
This presents an interesting problem for variadic functions that may optionally take non-integer arguments (e.g. printf style functions). Should non-GPR

Bar charts with error bars
I would like to add error bars to a bar chart, I have created in R. I am able to add error bars to a bar plot, but the same method does not seem to work for my bar chart version.
Is there a way to add error bars to bar charts?

Memory problem with GridCell*Editor
Alex,
I was getting the following crashes when editing cells in a grid:
./init.rb:1072:in `main_loop'': undefined method `begin_edit'' for
"_p_wxEvent":String (NoMethodError)
from ./init.rb:1072
but only after the first App GC mark phase.
So I changed all the GridCell*Editor.i files from GC_MANAGE to
GC_MANAGE_AS_EVENT. Which stopped the crashing. My question

SIMD interest
Greetings,
<p>my apologies for putting this trash in the mailing list but the topic
about SSE run-time option interested me pretty much.
Looks like some people is really experienced on the topic. I would
really appreciate if somebody could point me to good resources about SSE
and Altivec (not necessarly on the net, I'm ready to invest some money
if necessary). I already have intel

lme convergence failure within a loop
Hi R-users,
I'm attempting to fit a number of mixed models, all with the same
structure, across a spatial grid with data points collected at various
time points within each grid cell. I'm trying to use a 'for' loop to try
the model fit on each grid cell. In some cells lme does not converge,
giving me the error:

how to calculate the average values of each row in a matrix
Hello,
I have a matrix (class matrix) composed of GridCell (row and column).
The matrix value is the beta diversity index value between two grids.
Now I would like to get the average value of each GridCell.
Please kindly advise how to make the calculation.
Thank you.

[PATCH] Make SSE Run Time option. Add Win32 SSE code
Jean-Marc,
There is a big difference between SSE and SSEFP. The SSEFP means
that the CPU supports the xmm registers. All Intel chips with SSE support
do, however no current 32 bit AMD chips support the XMM registers. They
will support the SSE instructions but not those registers. You are right
about the SSE2 not being used.
The AMD Opterons are the first AMD CPU's which support

[LLVMdev] Bug #16941
Nadav,
The problem appears only for vectors longer than available hardware
register (in doubleword elements, i.e. more than 4 on SSE4 and more than 8
on AVX). Select does weird thing. <8 x i1> mask comes as two XMM registers,
select converts them to a single XMM registers (i.e. 8 x 16 bit),
immediately after it converts back to two XMM registers and does blend.
Conversion forth and back has
