Dear Ista,
that sos package is certainly something, didn't know there was one!
It turned out that ips is written by the same person who wrote phyloch,
so the latter must have been an alpha version of the former. The raxml
function worked from ips worked fine -- just a matter of defining the

Hi
Without going to deeply to your code; your data seems to be numeric, but for
some reason you read them as character. You shall consult read.csv help and
your original data. They probably have some feature which prevent them to be
read correctly.

Thanks to Duncan, Hadley and Henrik.
Duncan, I used Rprof and could pinpoint the critical routine that was
doing the memory crash.
Henrik, you got it right: the culprit was a big matrix of integers,
but where some of its fields are filled with -Inf and Inf. This matrix

I'm certain a google search will be sufficient to answer this question.

That is really helpful. I am trying to get the rmatch function to return
the position of the 'name' instead of the value. So rmatch(app, "FirsKey")
would return c(3,3,1). Then app[[c(3,3,1)]] <- 'new value' would be
perfect.

If you entered

Another function that should work is

hi pradip hope you're doing well! these two scripts have age adjustment
calculations, but neither are specific to nhis. the nhanes example is
probably closer to what you're trying to do :)

Hi Anthony,
Thank you for sending me your well-documented R scripts that are meant for
age-adjusted rate calculations. I will keep you posted on the implementation
of these scripts in the context of my analyses.

At first I thought that as.numeric() would do it, but that loses the matrix

I like this very simple version. Note that you don't need as.data.frame().
model.matrix(Freq ~ Hair + Eye, data=haireye,
