EpiTest.plot: Display variance component or directional epistasis graphs

Description

Display variance component or directional epistasis graphs

Usage

EpiTest.plot(
  ETest,
  Title = NULL,
  Family_names = NULL,
  Colors = NULL,
  Type = "mean",
  Alpha = 5/100
)

Value

a ggplot graph

Arguments

ETest

a list as obtained from the EpiTest.fit function

Title

(optional) a character string to be used as a title for the graph

Family_names

(optional) a character vector with family names

Colors

(optional) a character vector with three colors for the graphical display (for variance graphs only)

Type

a string with "mean" to display the directional epistasis plot or "var" to display the variance component graph

Alpha

type I error for the test, with 5% default value (for directional epistasis plot only)

Examples

data(Pheno.list)
data(Ancestry.list)

                                                    Weight = TRUE))
## Variance component plot
EpiTest.plot(ETest.nam,Title = 'Days to anthesis',Type = "var")

## Directional epistasis plot
EpiTest.plot(ETest.nam,Title = 'Days to anthesis',Type = "mean",Alpha = 5/100)
