Variance
I'm trying to find the variance of various outputs in a matrix:
for(l in 2:vl){
for(o in 1:(l-1)){
# Make sure the inputs are for the matrix "m"
input3=rownames(v)[o]
input4=colnames(v)[l]
r=t[(t$Rec1==input3 & t$Rec2==input4),output]
if(length(r)==0){
r=t[(t$Rec1==input4 & t$Rec2==input3),output]
}
v[l,o]=var(q,na.rm=TRUE)

starting Samba and removing PCNetlink
I have a Sun Clutster running on two Sun Fire 4800s, OS is Solaris 9.
The environment was set up with PC Netlink prior to my arrival. On Nov
24 after work I shutdown PC Netlink on both systems and started Samba.
However from the windows side we can only see one Sun box and the one
sun development box that I tested on prior to this weekend. The other
production system can't be seen from

transactions not work for array?
Hi,
I have a transaction block as follow:
begin
Hello.transaction(input1,input2)
input1.save
for i in 0 to count
input2[i].input1_id = input1.id
input2[i].save
end
end
rescue
end
I have used validates_uniqueness_of for input2 in the model
The problem is, when there is duplicate record in input2, input1 and the
first record in input2

matrix not working
Hello All,
I'm trying to create a matrix from a dataframe (let's call it df):
......a......b.....c.....d
a inputs output
b inputs output
c inputs output
d inputs output
e inputs output
The inputs are represented by columns a and b
The outputs are represented by columns c and d, but the only outputs are
those from column d
- some values from column d are

Pl. provide and Input for var.test (PR#716)
I want to use var.test function of ctest library. I was able to generate the
output from R on the input given by rnorm. But when I store the same data set
provided by rnorm into a file, and then read a file into a dataframe, then on
using the dataframe as a parameter to var.test function - it gives an error
"not enough x observations".

Readjusting the OUTPUT csv file
Dear R helpers
I have some variables say ABC, DEF, PQR, LMN and XYZ. I am choosing any three varaibles at random at a time for my analysis and name these files as input1.csv, input2.csv and input3.csv. So if I choose variables say ABC, DEF and PQR, I am passing the specifications of these variables to input1.csv, input2.csv and input3.csv respectively.
This means in another case even if I

Executing a function several time, how to save the output
Hi all,
I try to exceute a function "myfun" that should use as input "input1.csv"
and "input2.csv" .
Then I try to save the output dat33 on a csv file (on per each time I
execute input1..input 2 and so on). So my problem is how to finally obtain
several csv file with "ggt1.csv", "ggt2.csv".
The program creates ggt1.csv but

[LLVMdev] Tablegen: RegisterInfoEmitter.cpp
Hi,
I just bumped into a bug in this code. The problem was as follows:
I have defined a set of registers with rather similar names including digits.
The code section at
RegisterInfoEmitter::run(){
...
// Process sub-register sets.
runs and fills the RegisterAliases map.
then,

Macros in R
Dear members,
I have started to work with R recently and there is one thing which I could
not solve so far. I don't know how to define macros in R. The problem at
hand is the following: I want R to go through a list of 1:54 and create the
matrices input1, input2, input3 up to input54. I have tried the following:
for ( i in 1:54) {
input[i] = matrix(nrow = 1, ncol = 107)

R does not subset
Hi everyone,
I know there have been several requests regarding subsetting before, but
none of them really helps with my problem:
I'm trying to subset only infected individuals from the REC2 data.frame:

[LLVMdev] Vectorized LLVM IR
Hi,
We are experimenting directly generating vectorized LLVM IR (using <8 x float> kind of types), then compiling the code to SSE on a 64 bits machine. Right now the equivalent code in scalar mode sill outperform the SSE one.
What is the quality of the SSE support in X86 LLVL backend? Are they any specific things to be aware of to improve the speed?
Thanks

[LLVMdev] How to unroll reduction loop with caching accumulator on register?
I tried to manually assign each of 3 arrays a unique TBAA node. But it does
not seem to help: alias analysis still considers arrays as may-alias, which
most likely prevents the desired optimization. Below is the sample code
with TBAA metadata inserted. Could you please suggest what might be wrong
with it?
Many thanks,

Are the error messages of ConstrOptim() consisten with each other?
Dear Friends.
I found something very puzzling with constOptim(). When I change the
parameters for ConstrOptim, the error messages do not seem to be
consistent with each other:

Error in constrOptim(c(0.5, 0.3, 0.5), f = fit.error, gr = fit.error.grr, :
