can I get same results using lme and gls?
Hi All
I was wondering how to get the same results with gls and lme. In my lme, the 
design matrix for the random effects is (should be) a identity matrix and 
therefore G should add up with R to produce the R matrix that gls would report 
(V=ZGZ'+R). Added complexity is that I have 3 levels, so I have R, G and say H 
(V=WHW'+ZGZ'+R). The lme is giving me the correct results, I am

saving datafreame object problem
Do I miss here something?
dtaa = 
read.table("http://www.ats.ucla.edu/stat/mplus/examples/ma_snijders/mlbook1.dat",

head(dtaa)   # shows the data as it should be

d = load("c:/dtaa")
head(d)   # all data is lost, it only shows     [1] "dtaa" "dtaa"
Thanks for your hint on this.

opening a file from within a zipfile that is online
Hi
Reading the help for ?unz I was wondering if I can read data into R from within 
an zipfile that is on some website, like maybe:
dtaa = 
read.table(unz("http://www.ats.ucla.edu/stat/examples/alsm/alsm.zip","Ch01pr19.dat"))
Thanks for letting me know if you came acros such a thing before.

SIP invite timeouts : how is someone sending invites from our server ??

Averaging uneven measurements by time with uneven numbers of measurements
I have a new device that takes measurements anywhere from every second, to
every 15 minutes (depending on changes). The matrix has a date, time and Y
column (Y is the measurement). For three days it is 25,000 rows. How do I
average the measurements by every 30 minutes so my matrix is 48 rows per
day? I have been working on this and cannot figure out a simple method. Any
ideas? Thank you.

Tinc sudden spike in traffic usage
I just encountered a weird issue on my servers - Tinc was using a constant
10-50% CPU on several servers, and these servers were also receiving a
constant ~3 Mb/s of data over the Tinc interface, which is usually
otherwise pretty quiet.

Dropping coloumns while redaing dtaa from text file.
Hi
I have a huge text file and .dat file from which I want to read data. I do
not need all the columns in the files. I want to extract only some columns
from the .txt file or the .dat file, because reading the entire file is
becoming very difficult due to memory issues. Is it possible to extract a
few columns from .txt or .dat file while reading the data in R?
Thanks

Can anyone help explain to me why the two codes below have different result? I thought I can use log(time)~. to replace log(time)~dist+climb+timef.I am using CVlm from DAAG package. I think nihills is preloaded with the package. Thanks in advance.

1.4.38 passing a Regular expression containing a pipe character to a macro ?
Howdy,
I'm working on a macro that authenticates the calling extension against a
list of allowed extensions but it looks like the Expression I'm attempting
to send of  pipe separated extensions is showing up as additional arguments
to my macro.
I expected to have 4 arguments to the below macro, Instead it looks like I'm
actually getting 6.

Re: R-help Digest, Vol 24, Issue 28
You've omitted a comma. races2000 is a data frame,
which for purposes of extracting rows behaves like
a 2-dimenional object.  The following works fine:
   hills2000 <- races2000[races2000$type == 'hill', ]
Additionally, you might like to ponder
   > type <- races2000[names(races2000)=="type"]
   > type[1:4]
