In dmgatti/DOQTL: Genotyping and QTL Mapping in DO Mice

Find a Bayesian Credible Interval around a QTL.

Description

This function normalizes the area under the QTL curve on the given chromosome and finds a region that is 95

Usage

  bayesint(qtl, chr, prob = 0.95, expandtomarkers = TRUE)

Arguments

qtl	data.frame: four columns with SNP ID, Chr, position, and LOD in each column.
chr	character: the chromosome on which the QTL lies.
prob	numeric: must be between 0 and 1
expandtomarkers	boolean: if TRUE, expand the QTL interval to the nearest flanking markers. Default = TRUE.

Value

Data frame with the SNP ID, Chr, position and LOD for the left and right side of the interval and the maximum QTL.
