Your problem is numerical.
Try replacing

by
sum(log(dcauchy(x,mu,s)))
and see the difference. Here's what I get:

The a matrix has 30 elements, 5 rows, and 6 columns. You tell R to throw away

Thank you Duncan,
the paths were first so that wasn't the problem, but when I changed to the
directory of the file and then typed rcmd SHLIB it did work, like you said.
Great news.
Best,

Hi all,
I re-installed R and tcltk. I find some of the documentation misleading
as it indicates that tcltk is included with R. And when you type
library() it shows tcltk, even though it hasn't been installed.
Anyways, I've decided to go with sprintf.
I am having errors with my query criteria.

I'm writing a function that can take a data.frame as an argument. I'd
like to be able to obtain the name of the data.frame and print it out
within the function. My current function looks like this:
examineIt<-function(x) {
print(nrow(x))
print(x[ceiling(runif(10)*nrow(x)),])
print(summary(x)

Doh! Because I didn't read the docs properly and missed it.
Thanks, much n
Hi,
What R libraries should I use to implement mixed effects models with continuous
time and discrete-time survival data? What if I have two crossed random
effects? I'd appreciate any help.

I would say so; it would make sense.

Yes, definitely! so unlist() turns the list components into a vector? What if
the component are vectors, matrices etc? Thank you Miguel!

Hi!
Try: myMatrix <- as.matrix(myDataFrame)
Looking at ?data.matrix: "Return the matrix obtained by converting all
the variables in a data frame to numeric mode".
You could also do directly: myMatrix <- as.matrix(myList)
Though you might need to transpose (see ?t)
HTH,
