Plots the heat map for the LD LASSO solution space

Share:

Description

This function uses the matrix beta0.mat, computed by the function ld_lasso_method, to plot a heat map of LD LASSO solutions. Increasing darkness corresponds to increasing values for the SNP LD LASSO estimate.

Usage

1
heatmap( ldlasso.obj, s2.indx )

Arguments

ldlasso.obj

An ld lasso object

s2.indx

s2

Details

See vignette.

Value

A heat map is a visual representation of the matrix of LD LASSO estimates. Rows correspond to s2 values and columns correspond to SNP indices. The magnitude of the SNP estimate is represented by the degree to which the element is shaded. Increasing darkness corresponds to increasing magnitude.
