subsetting objects
I want to be able to exctract a matrix from a data frame that contains repeated measurements for individuals. i.e I want to exctract the second observation for each individual in the study.
Is there a way of doing this?
I guess what I am trying to ask is if there as a multidimensional version of aggregate() as in aggregate(data, list(data[,"ID"]), function(x) x[2,])
but aggregate will

NT_STATUS_UNSUCCESSFUL message-- were to look?
...folks,
I'm trying to access a shared printer on a windows machine. The
windows box (call it "Doze") is located behind a router/printserver,
and is set up thus:
-DOZE connects to the printer via the printserver using the PRTMATE
port, and then shares the printer via smb -- workgroup CHASS, server
name HIS-FACLAB, printer name his-fac-lex
-Router forwards all incoming connections on 137,138,139,445, and 1024
to DOZE
My linux box (Anarres) is outside the router, but I can browse the
router's network easily using Smb4K. I can access all SMB "Shares" on
DOZE without any...

Kendall's tau-c
Hello,
I can't find a package which calculates Kendall's tau-c. There is the
package Kendall, but it only calcuates Kendall's tau-b.
Here is the example from
ttp://www2.chass.ncsu.edu/garson/pa765/assocordinal.htm.
cityriots <- data.frame(citysize=c(1,1,2,2,3,3),
riotsize=c(1,2,1,2,1,2), weight=c(4,2,2,3,0,4))
cityriots <- data.frame(lapply(cityriots,function(x)
rep(x,cityriots$weight)))
xtabs(~ riotsize+citysize,cityriots)
tau-c should be .57.

Tests for Two Independent Samples
...egory 3;
72 observations in category 4; 2 observations in category 5;
To present the sample in R: b<-rep(1:5, c(6,127,297,72,2))
I want to test weather these two samples have significant difference in
distribution ( or Tests for Two Independent Samples).
I find a webside in: http://faculty.chass.ncsu.edu/garson/PA765/mann.htm
This page shows four nonparametric tests. Bust I can only find the test
Kolmogorov-Smirnov Z Test.
res<-ks.test(a,b)
Can any one tell me which package has the other 3 tests? or Is there any
other test for my question?
Thanks advance

: performing marginal tests to glm objects

: BIC for gls models
...n. I read in Pinheiro & Bates (2000) p84 that
BIC = -2logL + npar*log(N) (for the ML method), or
BIC = -2logLR + npar*log(N-p) (for the REML method)
but when I use any of these formulae I don't obtain the result given by R.
Thanks in advance for any help.

percentile-percentile plot
Hi,
Is there a function that does percentile-percentile plot. I do not mean
the qqplot. I need to plot the percentiles rather than points themselves.
I am hoping for a plot that tells me that the x percentile of one data set
corresponds to the y percentile of the other. for example a point on the
plot of (.5, .2) will tell me that the 50th percentile of the first data
and the 20th percentile of

gsub
Hi
A while back I used gsub to do the following
temp<-"000US00231"
gsub("something here", "", temp)
"00231"
I think it involved the `meta characters' somehow.
I do not know how to do this anymore. I know strsplit will also work but I
remember gsub was much faster. In essence the question is how to delete
all characters before a particular

[PATCH] support ruby in the xapian-bindings rpm spec
...indings for xapian recently and discovered
that the default .spec file doesn't support ruby by default. The
attached patch adds this support to the spec file in a manner
consistent (I think) with the other bindings.
I hope you find this useful.
