optim error
I saw a similar question but I still don't fully understand how to implement
optim.
Can someone help me out with this?
Thanks. Keun-Hyung

data type problem for vegan package
Dear all,
I'm using R2.8 version, and am trying to do NMDS and calculate other
diversity indices in vegan package.
The problem is that it works with a small set of data (43 X 23; row by
column), but the following error message comes up with a larger data set (43
X 104) (it seems not large to me at all). I made it sure that all data are
of numeric type as required.

read.table with many blanks (reposting)
Thanks Jim for pointing out how to properly ask.
Here is is my question and a small subset of the data and output.
I have a data set with many blanks. The blanks should be replaced with zero
once imported.
I tried read.table, read.csv (R 2.8 version),or scan, but none was
successful.
Any suggestion, please..
thanks.

row sum question
Dear helpers,
I'm using R version 2.8.0.
Suppose that I have a small data set like below.
[,1] [,2] [,3] [,4]
a 1 1 0 0
b 0 1 1 0
c 1 1 1 0
d 0 1 1 1
First, I'd like to find row sum of values uniquely present in each row, but
only sequentially from the top row, meaning that if the value is shown in
the above row(s) already, the

subsetting data points within confidence limit
Dear R-list
Suppose I have a data set stored in hmet, for which I did get confidence
limit on a linear regression as shown below.
My question is how I can subset only data points which are within the
confidence limit.
Thank you.

generating many matrices
I'd like to generate many matrices (let's say 100 matrices of 4x4), of which
diagonal elements are being drawn from each set of sample of known
distribution.
What would be the best way? I've been trying to find any previous threads
for this topic, but haven't been able to find one.
Thanks. Kevin

[LLVMdev] Qs on building LLVM passes
Hi,
I have couple of questions that those who design unconventional passes
would be interested in.
1. How to move a virtual register data to another new virtual
register?
It seems like that there is no LLVM instruction similar to mov machine
instruction.
Arithmetic or logical operators could be used for integer variables
but what about pointer variables?

[LLVMdev] Testcase for OS kernel
Hi,
The source attached at the bottom is a testcase which causes a back-end
error in LLVM 2.4.
These types of assembly routines are mainly used in OS kernels.
I checked that GCC 4.3 works for this routine.
The error messsage is ...
Couldn't allocate output reg for constraint 'A'!
I just need help or comments so that I could analyze and fix this bug.

[LLVMdev] How to correlate LLVA with native ISA
Thank your for reply.
The reason why these information are needed is that I am trying to extract
the program signature (e.g., control flow) out side of the binary.
Conventional compiler technique adds extra checking code into the target
source or target IR in an invasive manner. Since code generator combines the
added code with the original one, they don't need to correlate these two

Can you tell us what goal you are trying to accomplish that requires you
to do this? There might be better ways of doing what you want.
The answer to your question probably depends on whether you're trying to

Plotting coxph survival curves
Hi,
I am attempting to plot survival curves estimated by cox proportional
hazards regression model. The formula for the model is this:
F.cox.weight <- coxph(Surv(Lifespan, Status) ~ MS + Weight + Laid + MS:Laid
+ Weight:Laid, data = LongF)
MS = Mating status (mated/virgin)
Weight = adult female weight, continuous covariate
Laid = number of eggs laid by each female, continuous covariate

[LLVMdev] How to correlate LLVA with native ISA
Hi,
How to correlate the LLVM IR-leve instructions and memory values
with the machine instructions and memory locations?
For example, if CMP instruction in machine ISA is selected for the ICMP
instruction in LLVA,
with the Instruction datastructure for ICMP, is it possible to get the
memory address of CMP instruction? Assume that the code segment base address
is given.
Similarly, by

precision of do_arith() in arithmetic.c
To the R development team:
First of all, thank you so much for maintaining wonderful R software.
Perhaps, Dr. Ahn has just reported an error on the wilcox.test() function,
and suggesting that an error may arise from abs() and rank().
I just had a quick check that the problem may come from the precision of
the results of arithmetic functions.

Logistic regression with repeated measures
Hello R list,
I am hoping to conduct a logistic regression with repeated measures,
and would love an actual "code run through" for such an analysis. I
found only one related post on this list, but a full answer was never
provided. I understand that the routine lmer (or lmer2) in the lme4
package is often recommended in such a case, but actually implementing
it is where I've hit a
