Hi,
I am wondering what does "mypredict.lda<-function(object,

I run a few errorest commands in the same function on the same dataset using

"boot" and "632plus".
for example,in my data d,the value 1:9,NA is valid and the others are invalid.
and i want to report something like:
the variable z has invalid value.
is there any function to do so?

'RSiteSearch' is an R command new with R 2.0.0 or 2.1.0, I believe.
It essentially passes the argument string to "www.r-project.org" ->

work. When I have an R (or S-Plus) question for which I do not already

Isn't this the age-old story of the MacOS X Fortran compiler not fully
supporting compilation for dynamic libraries? Looks like the same
sort of problem it has with LAPACK code. You could try rewriting the code
to avoid DATA statements.
