tapply and names
I have a data frame containing children, with variables 'year' = birth
year, and 'm.id' = mother's id number. Let's assume that all the births of
each mother is represented in the data frame.
Now I want to create a subset of this data frame containing all children,
whose mother's first birth was in the year 1816 or later. This seems to
work:

read.spss: unrecognized record type
When reading an spss file, I get the following message:
Warning message:
../totmorH.sav: Unrecognized record type 7, subtype 13 encountered in system file.
What does it mean? Do I have to worry? The result looks as expected. I do
not have (easy) access to SPSS, so I cannot check exactly that I got what I
should have.
Thanks,

And, I'm using R-2.0.1 on Debian testing (from source).

Books on survival analysis and R/S
I will be giving a course in survival analysis using R (of course!) for
people who know nothing about the subject (including R), but know basic
statistics. I'm looking for a suitable course book. Therneau & Grambsch
(2000) is an excellent book, but too much for this course. I need somthing
more elementary.
I have a vague memory saying that such books exist, but I cannot find any

Pointer to covariates?
In the first line, use the dist function, found in library mva,
to get the distance between each pair of rows. From this
calculate an incidence matrix for which element i,j is true if
row i in dat equals row j in dat (and false elsewhere).
In the second line, for each row calculate the indices of
the matching rows and take the minimum of those as the key.

[Old '.so' file
I noticed the same thing as I reported below, when I upgraded from
R-2.0.0-alpha-20040918 to today's beta version:
'R CMD check' failed as before; but after cleaning 'src' from .o and .so
files, it worked again. So the two-day-old '.so' file is obviously different
from today's. Has compiler directives changed in the two last days? Or what
is happening?

'text' can't find "x"
I wanted to add some text to a plot and got (R-1.6.0, Linux):
> text(x = c(1, 4), y = 5, labels = x)
Error in text.default(x = c(1766, 1895), y = 5, labels = x) :
Object "x" not found
With the default value of 'labels':
> text(x = c(1, 2), y = 5, labels = seq(along = x))
Error in seq(along = x) : Object "x" not found
A scoping bug? :)

TeX distribution on Windows
I'm looking for a Windows distribution of TeX that works with R, after a
few years' absence from Windows. On Duncan Murdoch's Rtools page fptex is
still recommended, but it turns out that fptex is "defunct" as of May 2005,

Manova
Dear R-helpers,
In a data set I got from a medical doctor there are six treatment groups
and (about) 5 bivariate responses in each group. Using 'manova', it is
easy to see significant differences in treatment effects, but the doctor
is more interested in the correlation between the two responses (within
groups). I'm willing to assume a common value over groups, and one way

sample suggestion
I have been bitten by what is clearly described on the help page for
'sample', namely sampling from a population of size one. I agree that it is
convenient to have an exception if 'length(x) == 1', but my suggestion is
to enforce the exception only if 'x' is numeric. In any case, if x is not
numeric and of length 1, all you get is an error message.

row ("FORTRAN") order?
Reading about 'R_max_col' in "Writing R extensions", Version
2.1.0,(2005-01-03), I find:
"Given the nr by nc matrix matrix in row ("FORTRAN") order, ..."
Looks like a contradiction to me, since FORTRAN stores matrices
columnwise. So is this a documentation bug?

Underscore and ESS
This is a question that I should have sent to 'ess-help', but I
take my chances...
In 'NEWS' (1.9.0) I read the good news
o Underscore '_' is now allowed in syntactically valid names, and
make.names() no longer changes underscores. Very old code
...
but when I try it in emacs (ESS 5.1.24), my '_' are changed to ' <- '!
What can I do?

survreg: fitting different location parameters
Hi R-Help!
My question: I have lifetime/failure data of machines with different
stress levels and i think an weibull/extreme value distribution would
fit this data. So I did:
model1 <- survreg(Surv(lfailure)~stress,data=steel,dist="extreme")
(where lfailure=log(failure))
Now I would like to do a likelihood ratio test to test the hypothesis

Memory crash
Hello,
I get a segfault when running glmmboot in my own package glmmML. Has
happened many time before, but this time I get no hint of where in my C
functions the error might be. I give the output below. Can this be an R
bug? I suspect it has to do with repeated calls to 'vmmin' like this:

Error in the inverse of a diagonal matrix?
I?m new to R so maybe this issue has been asked before and I still could not read the complete set of past messages sent to the list.
I found a weird behabiour that I will explain with a simple example. Lets consider the following block of commands:

1.9.1-alpha & tty
I have two versions of R on my Debian testing: R-1.9.0 (precompiled) and
R-1.9.1-alpha of 2004-06-07 (built on my system). In the latter, I get
> system("emacs sim.R &")
> emacs: standard input is not a tty
while with R-1.9.0 it works as expected. I have absolutely no idea about
what's going on, so I could use some help. Anyone?
Thanks,
