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.

'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? :)

link in FAQ incorrect (PR#833)
Hi,
the link to the R code for repeated measurement analyses of J Lindsey is
unfortunately not working. I am desperate for repeated measurements in
R; could you please help me out.

Finding indices with a certain property
I want the indices i for which x[i] < 0 (say):

Surely where.negative is something simple, but how?

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?

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

R-1.6.0 is released
I've rolled up R-1.6.0.tgz a short while ago. This is a major upgrade,
with several new features.
A few of the changes generate compatibility issues. You may wish to

Handling dates
I have a problem with some functions handling dates, in packages 'date' and

Given a month, day, and year, returns the number of days since January 1, 1960.

coxreg vs coxph: time-dependent treatment
Dear List,
After including cluster() option the coxreg (from eha package)
produces results slightly different than that of coxph (from survival)
in the following time-dependent treatment effect calculation (example
is used just to make the point). Will appreciate any explaination /
comment.
cheers,

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