discriminate analysis
Dear List,
I'd like to run a discriminate analysis on a data set, but have no idea
how to go about this in R. I have attempted to locate info in the manuals,
but may not be consulting the right sections or documents.
Can anyone point me to appropriate documentation if such exists.
Many thanks,

segmentation fault with 1D array (PR#500)
Here's a nasty one. The following has caused a segmentation
fault and possibly also a bus error.
fred <- 1:6
dim(fred) <- 6
dimnames(fred) <- list(LETTERS[1:6])
mm <- matrix(1:12, 2, 6)
mm %*% fred # segmentation fault here
In the case without the dimnames assignment the result is OK.
Cheers, Jonathan.

Surprisingly, I do not obtain the same results for the coordinates of
the principal composantes with these two softwares.

manipulating "..." inside a function
Dear R-help,
Can some one tell me how to do the following (if it's possible)?
Suppose I have a function like this:
f <- function(x, y, ...) {
## some code
g(x, y, ...)
## some more code
}
The problem is that g() may not understand everything that comes through in
"...". Is there a way to delete some component of "..." and then pass it to
g()?

The have the same number of rows, and each has several columns,

are repeated in file2.
Using the "foreign" package, I can read these in separately
