glm analysis repeated for 900 variables
...s only output of the last variable
for (i in 1:length(data)) { glm.data[[i]] <- glm
(outcome~data[[i]]*phenotype, data=data)) }
summary (glm.data[[i]])
# gives only output of the last variable
Or should I use tapply or something like that? In what way?
Thanks!

Major difference in the outcome between SPSS and R statisticalprograms
...ard errors that account for the correlation of
individuals within similar units whereas the SPSS procedure will not.
The lmer standard errors better capture the true sampling variance of
the parameters and SPSS doesn't.

trivial list question
Dear experts,
For the makeGenotype function I need a list as in the example. However,
since my list needs to be 184 long there must be an easy way to make it.
>list(1:2,3:4,5:6,7:8)
[[1]]
[1] 1 2
[[2]]
[1] 3 4
[[3]]
[1] 5 6
[[4]]
[1] 7 8
I have tried
lis<-1:184
dim(lis)=c(92,2,1)
as.list(lis)
and several other options. Any suggestions?
many thanks
Marco

Replacing matching values by related values
I am trying to replace values of a vector (consisting of 15 values) by a value that is related to a matching value in a dataset (consisting of 17 rows).
Here's an example
The vector:
v <- c(f,a,e,d,m,o,e,f,i,n,e,i,b,a,o)
The dataset's columns consist of the following values
d[,1] <- c(a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q)
d[,2] <- 1:17

Dear R users,
This command works (calling a programm -called whap- with file specifiers etc.):

Now I need to call it from a loop to replace the "1" by different number, however I get lost using the quotes:

Textmate project drawer: is there a Windows alternative?
I was reading about the project drawer feature in Textmate, which is Mac
only.
Is there a similar feature in a Windows based text editor that works with R.
This feature sounds really useful.

reordering huge data file
Dear R-experts,
My problem is how to handle a 10GB data file containing genotype data. The file is in a particular format (Illumina final report) and needs to be altered and merged with phenotype data for further analysis.
PERL seems to be an frequently used solution for this type of work, however I am inclined to think it should be doable with R.
How do I open a text-file, line by line,

Routing(?) issue
Hi,
this has nothing to do with CentOS but with your router which does not
support using the public IP from inside your network (which is quite
common).
If the port is open on your router when you access it from another
public IP then all is well.
Regards,
Michel

Major difference in multivariate analyses SPSS and R
Dear colleagues,
I know SPSS can not compute linear mixed models. I used 'R' before for
computing multivariate analyses. But, I never encountered such a major
difference in outcome between SPSS and 'R':
In SPSS the Pearson correlation between variable 1 and variable 2 is 31%
p<0.001.
In SPSS binary logistic regression gives us an Odds Ratio (OR)=4.9 (95%
CI 2.7-9.0),

This indicates that the protocol got corrupted somehow because that is
saying that the receiver got a MSG_DELETED message with a 7104843-byte
buffer attached (which rsync is telling you is too big), but you're not
even deleting files. What version of rsync are you using?
