trigger-loclink: Estimate local-linkage probability for each gene

In igbucur/trigger: Transcriptional Regulatory Inference from Genetics of Gene ExpRession

Description

A method of class trigger to identify the best local-linkage marker for each gene and compute the local linkage probabilities.

Usage

 	## S4 method for signature 'trigger'
trigger.loclink(triggerobj, gender = NULL, window.size = 30000)

Arguments

triggerobj	An object of class trigger.
gender	Optional. When computing linkage statistics involving markers on sex chromosome, gender of each sample should be specified.
window.size	Optional. The size of a window that places the putative regulator gene in the center. Every marker within the window is a candidate marker for local-linkage to the regulator gene.

Value

An updated object of class trigger containing a slot loc.obj with fields:

prob.loc	The estimated local-linkage probability for each putative regulator gene.
loc.idx	The indices of the best local marker for each putative regulator gene.

Use slot(triggerobj, "loc.obj") to retrieve the list.
