[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?

C basic indentation

Ordering long vectors
I need to order a long vector of integers with rather few unique values.
This is very slow:
> x <- sample(rep(c(1:10), 50000))
> system.time(ord <- order(x))
[1] 189.18 0.09 190.48 0.00 0.00
But with no ties
> y <- sample(500000)
> system.time(ord1 <- order(y))
[1] 1.18 0.00 1.18 0.00 0.00
it is very fast!
This gave me the following idea: Since I don't care

Two names of a function
Is it possible to let a function be known under two names without having
two identical copies of the function body?

'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? :)

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,

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

Numeric to factor
I find 'How do I convert factors to numeric?' in the FAQ (7.12), but not
the other way around. Trivial maybe, but
> codes(factor(c(2, 10))
[1] 2 1
> codes(factor(c(2, 9)))
[1] 1 2
How do I get the levels attached to the codes in numeric order?

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:

new package: eha
A few days ago I uploaded to CRAN a new package called 'eha', which
stands for 'Event History Analysis'. Its main focus is on proportional
hazards modeling in survival analysis, and in that respect eha can
be regarded as a complement and an extension to the 'survival'
package. In fact eha requires survival. Eha contains three functions
for proportional hazards

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?

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,

optim/vmmin and R_alloc
I am calling 'vmmin' several times from a C function (which is called via
.C). It works very well, except for memory consumption. The cause is that
vmmin allocates memory via R_alloc, and this memory is not freed as vmmin
exits. Instead all the allocated memory is freed on return of the .C
call.
In one application, I have 2000 functions of 500 variables each to
minimize. In each call to
