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:

Random number from density()

I'm writing some genetic simulations in R where I would like to place
genes along a chromosome proportional to the density of markers in a
given region. For example, a chromosome can be presented as a list of
marker locations:

replacing value in column of data frame
Dear all,
Probably a very basic question but I need some help.
I have a data frame (made by read.table from a text file) of microarray data, of which the first column is a factor and the rest of the columns are numeric.
The factor column contains chromosome names, so values 1 through 22 plus X, Y and XY. The numeric columns contain positions or intensity measurements.

list genes w/n a genomic fragment
Hi, is there any package/function in Bioconductor that can do this: if given
the chromosome positions of a fragment, find out all genes within, and with
the information about which strand is the sense strand. And vice versa.
Thanks a lot.

Appreciate your time & attention!

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:

minor allele frequency comparison
Hi all,
We are using two methods to identify SNPs. One is based on resequencing
the genome and aligning the reads to the sequenced genome to identify SNPs
(data available for 44 individuals). Another is based on SNP array with
selected loci (30000 loci, 870 individuals). I want to compare the results
from the resequencing based minor allele frequency and Array based minor
allele frequency.
