Hi Stéphane,
The SSE support is the LLVM backend is fine. What is the code that's generated? Do you have some short examples of where LLVM doesn't do as well as the equivalent scalar code?

[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

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

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 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

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".
I'll explain the above mentioned problem of

random effects in analysis of variance
I have a data.frame paint (below-mentioned). In SPlus I used the command
raov( MOISTURE ~ BATCH / PROBE )
(you could do raov( MOISTURE ~ BATCH + PROBE%in%BATCH) as well)
so that the factors are taken as random. In R this function raov doesn't
exist. How can I calculate the same? Maybe with lme, but how?

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"

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

Best filesystem?
Hi everyone! What's the best filesystem to use for the mail spool? I'm
debating between Debian with xfs or FreeBSD with zfs. I'm not sure which
way to go. I'm migrating from cyrus. I have about 50 users so it's not a
large setup.
Cheers!

M-estimation in multivariate linear regression model in R
Hello,
I try to find a function for M-estimation in multivariate linear regression
model (function that can estimate betas in my model: y=x * beta + e, where
y is a matrix). I´ve searched R-site for a long time, but I am hopeless.
I would like to ask, if there is any function for M-estimation in
multivariate linear regression model in R. I know I can estimate betas in
my model by rlm() function

using read.table, removing extra quotation mark from a text field? (e.g. ""cat" )
I am using read.table to import a text file within R.
There are several "errors" in my text file. An "extra" quotation mark has
inadvertently been included within a few text fields.
e.g. for a pipe (|) delimited text file, I have something similar to this:
1|7|30| "dog"
2|6|25| ""cat"
3|4|20|""
4|5| 56| "mouse"
5|3|56|
