Hi: I don't know anything about gentoypes but it sounds like you overfitted
the training set so you should try using regularization. In standard
svm-classification algorithms, that can be done by decreasing the parameter
C which decreases the objective functional penalty for mis-classifying. (

Frans,
I'm not sure I understand what you're after.
I suggest that you share a small example data set, using dput().
Then give an example of what you want the output to look like.

Dear list
I've a generic question about how to tune an SVM
I'm trying to classify with caret package some population data from a
case-control study . In each column of my matrix there are the SNP
genotypes , in each row there are the individuals.
I correctly splitted my total dataset in training(1

Yes, it does thanks. Before your explanation I didn't understand that I had to
separate distancer and y with a comma...great!

Hello,
Simple question with reproducible example code.
The best way to go is to know to what dimension you want to apply the
function, the 1st, and to write the function in such a way as to have
the passed rows as the first argument. If it has other arguments, they
go after. Since your functio
Dear subscribers,
I have made a simulation using loops rather than apply, simply because the loop
function seems more natural to me. However, the current simulation takes
forever and I have decided - finally - to learn how to use apply, but - as many
other people before me - I am having a hard

If you really want DCred1, DCred2, etc, you'll need to use assign() and
paste() within your loop. But he's a more R-ish way:
# Differences of Cred
DCred <- list()
for(i in 1:5){
print(DCred[[i]]<- diff(DCred, lag=i, difference=1))
}
DCred[[1]]

Dear R Users,
Sorry for what seems like I am re-posting. When I was typing my initial

HI,
I am working on R and Latex.
R CMD Sweave Test.Rnw (this generates Rnw.Tex file )

Is there any way to change the name of of output file (Test.pdf). I want it
to pass the output file name as parameter.

Thank you for your response, I will try to be clearer. I would like to fill my
lattice histogram bars using a symbol rather than a color. If that is not
possible, then I will use hist() instead.

bar.fill only includes "col", so perhaps I'm out of luck?

Function DEoptim in package DEoptim for differential evolution defines an
optional parameter fnMap:
fnMap
"an optional function that will be run after each population is created, but
before the population is passed to the objective function. This allows the user
to impose integer/cardinality c
