segregationRatios: Compute observed segregation proportions for dominant markers...

In polySegratio: Simulate and test marker dosage for dominant markers in autopolyploids

Description

Computes segregation ratios for a matrix of markers where the rows are markers and the columns are individuals and the markers are recorded as 0's and 1's

Usage

segregationRatios(x, drop.cols = NULL)

Arguments

x	matrix of 0's, 1,s and NA's representing scores of dominant markers where the rows are markers and the columns are individuals
drop.cols	numeric columns to drop when calculating segregation ratios

Value

Returns an object of class segRatio containing

r	no. of 1's for each individual
n	total no. of markers present for each individual
seg.ratio	segregation proportion for each individual
n.individuals	total number of individuals
