structural equations using sem package
Hello
I am using sem to look at the direct effect of one variable on another but i am uncertain if i am progressing correctly.
An example:
covar1<-? matrix(c(0.4,-0.2,3,-0.2 , 0.3,-2 , 3 ,-2 , 60), nrow=3,byrow=T)
rownames(covar1)<-colnames(covar1)<-c("endo","exo","med")

Programming Problem (for loop, random # control, 3 dimentional graph)
Dear List,
This is just a programming problem which i cannot seem
to figure out. I am trying to get a set of power from
a test (say, kolmogorov smirnov) out of a distribution
(say, G-K distribution) as follows. I am trying to
reduce to pain of writing the whole set of data points
(p# below) using "for" loop. However, I seem to have

Proportion test in three-chices experiment
Hi,
I wish to analyze with R the results of a perception experiment in which
subjects had to recognize each stimulus among three choices (this was a
forced-choice design). The experiment runs under two different
conditions and the data is like the following:
N1 : count of trials in condition 1
p11, p12, p13: proportions of choices 1, 2, and 3 in condition 1
N2 : count of trials in

Help with installing add-on packages
Dear R users.
Recently I wanted to update my R distribution to the current one (R-2.7.1). I am running a Fedora core 8 distirbution. The installation went fine, but when I tried to add some additional packages the majority made an exit with an error. Only a few least demanding (e.g. RColorBrewer) managed to get through the installation process.
What happened between the versions 2.6.x and 2.7.x

Problem with sample()
Hi,
I'm having a problem using sample() within a function.
Basically I get an error reading:
Error in sample(v, 1, prob = h) : non-positive probability
Can anyone advise me as to the possible origin of this error?
Here is my code

Problem installing packages in newer versions of R
Dear all,
I was wandering what could be wrong with my system (regularly updated Fedora core 8) so that installing packages does not succeed with almost every package. I follow the procedure specified in the help file R-admin section 6.3. This is not a feature new to the current version but happened (to me) in the previous version as well. Additionally R-help html pages try to follow wrong links

a prolem with constrOptim
Hi,
I apologize for the long message but the problem I encountered can't be stated in a few lines.
I am having some problems with the function constrOptim. My goal is to maximize the likelihood of product of K multinomials, each with four catagories under linear constraints on the parameter values. I have found that the function does not work for many data configurations.

data management
Dear Rxperts,
I have a varaibles data file that looks like this
p(1) 10
p(1) 3
p(1) 4
p(2) 20
p(2) 30
p(2) 40
p(3) 4
p(3) 1
p(1) 2
I cannot process these data with R because it does not like the parentheses.
How can I get these to look like:
p1 10
p1 3
p1 4
p2 20
p2 30
p2 40
p3 4
p3 1
p3 2
The data is in a tab delimited text file and I want to get it into a
data.frame().
Many thanks in

How to select a whole column? Thanks!
Dear all,
I hope to remove a whole column from a data frame or matrix (> 2000
columns). All value in the column are same. The first thing is to
select those columns.
For instance, I hope to remove the V3~6 column, for all the value in
those colume is zero.

[PATCH 2/5] Xen/MCE: vMCE injection
Xen/MCE: vMCE injection
In our test for win8 guest mce, we find a bug that no matter what SRAO/SRAR
error xen inject to win8 guest, it always reboot.
The root cause is, current Xen vMCE logic inject vMCE# only to vcpu0, this is
not correct for Intel MCE (Under Intel arch, h/w generate MCE# to all CPUs).
This patch fix vMCE injection bug, injecting vMCE# to all vcpus.
