getDropoutData: Get drop-out events

Description

getDropoutData extracts the drop-out information from a data set where drop-outs have been calculated.

Usage

getDropoutData(data)

Arguments

data

data frame with genotype data in "GeneMapper" format. Requires at least columns 'Marker' (locus names), 'Height' (Height.1 and Height.2), 'Dropout' (no dropout '0', allele '1', and locus dropout '2'), 'Heterozygous' (heterozygous '1' or homozy

Value

• data.frame a data frame with the following columns 'Marker' (locus name), 'Height' (peak height in rfu of the surviving allele), 'Dropout' (indicates if the sister allele has dropped out '1' or not '0').

Details

Extracts loci, heterozygote peak heights, and dropout status from dataset. Required columns: 'Marker' with locus names, 'Height.1' and 'Height.2', 'Dropout' with dropout status as described for calculateDropout, 'Heterozygous' with 1 for heterozygous loci and 0 for homozygous loci. Gets all observations (e.g. 90/0, 105/95 -> 90-1, 105-0, 95-0)
