make.regressor.matrix: Create regressors using expected marker values

In bqtl: Bayesian QTL Mapping Toolkit

Create regressors using expected marker values

Description

Create regression variables for markers and loci between or near markers by imputation conditional on known marker states.

Usage

make.regressor.matrix(state.matrix, mode.mat=NULL)

Arguments

state.matrix	A state.matrix.object - see make.state.matrix for more details
mode.mat	A matrix which indicates the values of regressor variables corresponding to the allele states. If mode.mat=NULL (the default) a mode.mat is inferred from the dimensions of state.matrix. For the F2 intercross these are typically additive and dominance codes like (-1,0,1) and (1,-1,1). For BC1 backcross and RI lines, typically the values are (-1,1).

Value

A matrix with variables suitable for use as regressors.
