Genetic Algorithms with rbga.bin using AIC as the evalFunc
Hi all.
I would like to use the rbga.bin function (from the "genalg" package) as
part of a model selection process to whittle down a list of ~40
potential explanatory variables to only the most important ones.
Unfortunately, despite my working knowledge of R for linear modeling and
basic statistics, I cannot understand the two examples provided with the
documentation for rbga.bin

ga: genetic algorithms package
Dear all,
at the following address
http://linaria.dst.unive.it/~claudio/R/Rmaterial.html#ga
you can download a package to build simple genetic algorithms. I wrote
this package to introduce genetic algorithms to student in labs, which
means, the package emphasize "how a ga works" instead of "how
fast it could be".
Please, let me know any comments or suggestions,
Bests,

mcga 1.1 (machine coded genetic algorithms) package released
mcga 1.1 (machine coded genetic algorithms) package implements a genetic
algorithm optimisation tool with machine coded chromosomes.
The machine coded chromosomes stand for chromosomes that are not decoded and
encoded. The byte representation of 'double' type variables are crossed-over and
mutated. This is different from the binary coded and real coded genetic
algorithms. Linux and

how to install freephoneline.exe from CLI
Looking at:
http://appdb.winehq.org/objectManager.php?sClass=application&iId=10591
What are the steps to install this application? Yes, it's a garbage
application, but I'd like to at least give it a go. Looks like msiexec
apparently isn't the right approach. Should that be through wcmd instead?

vfs_ChDir fails, even though the share is read-write for that user
Hi,
I'm running Samba Version 3.0.25c on Solaris 10 8/07 on X86 hardware.
It's successfully joined to AD.
But, and there always is a but, if :
* A user is a member of SomeGroup
* and the share alllows SomeGroup to access it
* and SomeGroup is NOT what the user has set as their Primary Group in
Active Directory
then
* Samba will recognize that the user can access the share

MVC interplay to query multiple models
I''m trying to track down why I''m getting close to desired output, but not
quite. It looks like the webpage sorta-kinda is grabbing the right
data. For instance, there are three Login objects which should be
showing and it looks like the show is grabbing three objects, so that
fits, to a degree. However, it''s just grabbing the hexadecimal object

general genetic algorithm / simulated annealing framework
Hi,
we have some code that does variable selection with a genetic
algorithm or simulated annealing, using a linear regression routine or
neural network as the objective function. This code is a mixture of
fortran and C.
The code is more than 15 years old and I am planning to rework it.
Though a C rewrite would be good for efficiency, I would like to
protoype it quickly in R and see how it

Genetic algorithm for feature selection
Hi,
I'm looking for a R-package that does feature selection for PLS using a
genetic optimization algorithm.
I couldn't find one on CRAN and I wonder whether there is a free one. I
would be very appreciative for any help.

how to use GenABEL genetic information??
Does anyone use the R library GenABEL? I am using it to calculate SNP
interactions.
I have a list of 100 SNPs, I need to look at the interaction between each of
two SNPs among the list. my question is how to perform this in GenABEL. I
want to use the "lm" function, but don't know how to use the SNP
information.
for example:
result <- (lm(y~SNP1+SNP2+SNP1*SNP2))

Composing a matrix for 'heatmap' from original dataset and genetic data analysis.
Hello.
I have following data:
doze g1 g2 g3 g4 etc...
1200 a d
1100 b e
1158 c f
1500 a e
1403 c f
...
etc.
Doze - numeric, levels(g1)=c('a','b','c'), levels(g2)=c('d','e','f').
This is the data of genetic analysis, where the factors are genes and
the numerical is some numerical value.
I want to build up a function, which will do a preliminary

Accounting for within family correlation in genetic analysis
I am hoping for help with a genetic analysis.
I am trying to perform an analysis of the relation between genes at a given locus (rs2304795) and a phenotypic trait (zerotg). Multiple subjects are recruited from each family (and so share a part of their genome and are correlated). Family groups are identified by the variable FAMILY. For each subject multiple measurements are made of the trait of

R, joint scaling test, quantitative genetic analysis & sensitivity to model violations
Hi all, This is really a stats question as much as an R question. I'm
trying to do a joint scaling test (JST - see below) on some very
oddly-distributed data and was wondering if anyone can suggest a good way of
dealing with model violations and/or using R to evaluate how sensitive the
model is to violations of the normality assumption.
Here's a quick explanation of the analysis, the
