plotVariableMatrix {ggenealogy}

Returns the image object to show the heat map of dates between the inputted set of vertices

Description

Returns the image object to show the heat map of dates between the inputted set of vertices

Usage

plotVariableMatrix(
  varieties,
  geneal,
  colName,
  xLab = "Variety",
  yLab = "Variety",
  legendLab = "Difference in variable"
)

Arguments

varieties

subset of varieties used to generate the heat map

geneal

the full genealogy (in data frame format)

colName
