curvilinear grid
Hello all:
A question from a new user. I have data on a geo-referenced curvilinear
grid. This is a grid with 75 rows and 51 columns, is not aligned
north-south, and the rows and columns are not straight. (And the
coordinates are in meters.) I want to make image plots of this data,
but where the grid is deformed according to the correct locations of the
grid points, instead of coming out

R genetics package now available
The "genetics" package for handling single-locus genetic data is now
available on CRAN in both source and Windows binary formats. The purpose of
this package is to make it easy to create and manipulate genetic
information, and to facility use of this information in statistical models.
The library includes classes and methods for creating, representing, and
manipulating genotypes

Reshaping genetic data from long to wide
Bottom Line Up Front: How does one reshape genetic data from long to wide?
I currently have a lot of data. About 180 individuals (some
probands/patients, some parents, rare siblings) and SNP data from 6000 loci
on each. The standard formats seem to be something along the lines of Famid,
pid, fatid, motid, affected, sex, locus1Allele1, locus1Allele2,
locus2Allele1, locus2Allele2, etc

R for Windows crash on new laptop
I'm trying to use a contributed package (rmetasim) to generate simulated
genetic datasets. My scripts work fine when I run them on a Sun
workstation running Solaris 7 and when I run them on a ~4 year old
laptop PC that I have. However, when I run them on my new laptop (Dell
Latitude D410 purchased in August 2005), the simulation will run for a
short (variable) period of time, then R

R for Windows crash on new laptop - corrected script
I realized that the script I included in my original post (see below)
was written for an older version of rmetasim and will not work with the
current version. The only change that need be made to get my script to
run with the latest release of rmetasim is to change the command
'simulate.landscape()' to 'sim.landscape()'. My apologies to anyone who
tried to use my script and

classifly 0.2.2
The classifly package uses rggobi to visualise classification
boundaries in high-dimensions. Given p-dimensional training data
containing d groups (the design space), a classification algorithm
(classifier) predicts which group new data belongs to. Generally the
input to these algorithms is high dimensional, and the boundaries
between groups will be high dimensional and perhaps curvilinear or

Repeating tdt function on thousands of variables
I am using dgc.genetics to perform TDT analysis on SNP data from a cohort of
trios.
I now have a file with about 6008 variables. The first few variables related
to the pedigree data such as the pedigree ID the person ID etc. Thereafter
each variable is a specific locus or marker. The variables are named by a
pattern such as "Genotype.nnnnn" with nnnnn corresponding to a number which

How to create a chromosome location map by locus ID
Hi,
I'm trying to make a chromosomal map in R by using the locus. I have a list
of genes and their locus, and I want to visualise that so you can see if
there are multiple genes on a specific place on a chromosome. A example of
what I more or less want is below:

data conversion (possibly with reshape package)

I have an issue with a data conversion. First, I tried it with the

stats 'dist' euclidean distance calculation
Hello,
I am working with a matrix of multilocus genotypes for ~180 individual snail samples, with substantial missing data. I am trying to calculate the pairwise genetic distance between individuals using the stats package 'dist' function, using euclidean distance. I took a subset of this dataset (3 samples x 3 loci) to test how euclidean distance is calculated:

computer out of memory when using sigpathway
Dear R users,
I am sorry to disturb you! But I really need your help for the usage of sigPathwy.
Actually, I want a sliding window analysis for possible chromosome expression pattern mining. My research microorganism is a plant pathogen, Gibberella zeae, and I first used SAS to divide locus number with 10, 20, 30, or 40 on the fungal chromosome according to their location. I really
