A matrix containing genotype probabilities.
Multiple chromosomes and the multiple genotypes at each position are
pasted together.
Arguments
cross
An object of class cross. See
read.cross for details.
chr
Optional vector indicating the chromosomes to consider.
This should be a vector of character strings referring to chromosomes
by name; numeric values are converted to strings. Refer to
chromosomes with a preceding - to have all chromosomes but
those considered. A logical (TRUE/FALSE) vector may also be used.
omit.first.prob
If TRUE, omit the probabilities for the first
genotype at each position (since they sum to 1).
include.pos.info
If TRUE, include columns with marker name,
genotype, chromosome ID, and cM position. (If
include.pos.info=TRUE, we take rotate=TRUE.)
rotate
If TRUE, return matrix with individuals as columns and
positions/genotypes as rows. If FALSE, rows correspond to individuals.
