subset function within a function
Hi,
I am using this subset statement and it works
outside a function.
LIS[[i]]<- lapply(LI, subset, select=cov[[i]])
However, wrapped inside a function this statement
produces the same values for every LIS[[1]] which
is only the first subset of LI.
Does anyone know why is not working correctly inside
a function?
ff = factor(covariate)
nLev <- nlevels(ff)
cov <-

Hi,
I am trying to compile the R-dev version on a unix Suse machine

Can someone suggest an efficient way to substitute a vector/matrix
which contains 1's and 0's to P's and A's (resp.)?

graphing with error bars
I am not able to find information about doing line plots with error bars in the R- help information.
Would someone like to tell me if this can be done in R and either get me started or lead me
to information about how to do the error bars?
Thanks,

Multiresponse parameter estimation
I am looking for a way to do multiresponse parameter estimation for a
problem that is quite similar in form to the alpha-pinene example in Bates
and Watts (1988), p. 147, where the model is a set of ODEs. I am
specifically interested in obtaining the parameter covariance matrix, as
well. Which package(s) in R would I use to do such a thing?

if else statement
Hello,
I'm doing some scripting and I've noticed that R doesn't seem to
have an
if (cond){
do
}ifelse (cond) {
do
} else {
do
}
type block.
Is this correct or am I missing something.

comparing poisson distributions
Hello all,
I would like to compare two sets of count data which form
Poisson distributions. I'd like to generate some sort of p-value of the
likely-hood that the distributions are the same. Thanks in advance for
your advice.
Cheers,

data type for block data?
Dear All,
I have a matrix with data that is not organised. I would like to go
through this and extract it. Each feature has 2 vectors which express
the data. I also have an index of the places where the data should be cut.
eg.
>class(cc)
"matrix"
>cc

[1,] 1 26
[2,] 2 27

Samba, Winbind, and netatalk on Solaris 8
I am having difficulty getting Netatalk to authenticate using NT Domain via
Winbind.
I have Samba successfully installed, and winbindd is working and running.
(Tested via wbinfo)
I have placed pam_winbind.so in the /usr/lib/security directory, and have
installed netatalk with the --with-pam option, but I still cannot seem to
get it working.
Any help would be appreciated.

Nodes & edges with similarity matrix
Hello,
I apologise if someone has already answered this but I searched and
googled but didn't find anything.
I have a matrix which gives me the similarity of each item to each
other. I would like to turn this matrix into something like what they
have in the graph package with the nodes and edges.

better define: matrix comparison and cbind issue
Hello,
Sorry to all for the lack of communication, and thanks to those with the
suggestions.
So I have two matrixes which are different sizes, same column number but
different row number.
What I would like to do is to compare A to B. In the 6 and 9th column there
are ref numbers (molecular masses to be exact). I would like to check A and
B by these columns. If I find that the number in A[9,x]

gluster and rocks?
Is anyone using Gluster with the Rocks cluster system? If so, do you
know if there is a Roll for Gluster? Or, do you have any advice about
things to do and things to avoid doing?
We're considering using Gluster with Infiniband on our cluster and
trying to learn whether other people have done this so we can perhaps
learn from their experience.
Thanks.

Time plots
Hello all and thank you,
I will try to make this as clear as I can. I have a matrix, at the
top of the matrix are 4 time points, the first col describes the sample,
then under each time point I have the intensity values of that sample.
So :
Samples 0 10 30 120 <- time
A 200 300 400 1000 <- data
B 100 400 200 100
C 500 400 200 1000

I hope this isn't too long, and I hope it's the correct list.
I have a network configuration where I have 2 hosts, A and B. Each has
a local LAN on which the run Samba, plus they're connected by a VPN. So
has A has addresses lanA and wanA, and host B has addresses lanB and

viewing data in something similar to 'R Data Editor'
Hi,
I would like to view matrices I am working with in a clean, easy to read,
separate window.
A friend showed me how to do something like I want with edit(). I can view
the matrix in the 'R Data Editor':

Winbind issues! HELP!
OK. This is becoming very frustrating!!
I have Samba 2.2.3a installed on a Sun running Solaris 8. Winbind is
installed and seems to be working fine. My PC users can map the Samba share
via their NT domain account information (PDC is an NT4 box).
As soon as I copy nsswitch/libnss_winbind.so to /lib and create the symbolic
links (nss_winbind.so.1 & nss_winbind.so.2) my PC users can no
