R Documentation

Plot phenotypic effects for two markers as a heat map

Description

This internal function is called by plot_effects to generate a heat map showing the effects of genotype on phenotype. This function fits linear models to the markers and traits. It then uses these models to predict trait values at different genotype combinations in a 2D grid. It plots these predicted values in a heat map.

Usage

plot_int_heat(
  phenoV,
  marker1_vals,
  marker2_vals,
  pheno_name = NULL,
  marker1_label = NULL,
  marker2_label = NULL,
  bins1 = 50,
  bins2 = 50
)

Arguments

`phenoV`	A vector of trait values
`marker1_vals`	A vector of genotype values for marker1
`marker2_vals`	A vector of genotype values for marker2.
`pheno_name`	A string indicating the name of the trait being plotted.
`marker1_label`	A string indicating the name of marker1
`marker2_label`	A string indicating the name of marker2
`bins1`	The number of bins for marker1 over which to predict values of the trait. This can also be a vector specifying those bins.
`bins2`	The number of bins for marker2 over which to predict values of the trait. This can also be a vector specifying those bins.
