scatterHatch: Creates a scatterplot with hatched patterns.

In FertigLab/scatterHatch: Creates hatched patterns for scatterplots

Creates a scatterplot with hatched patterns.

Description

This function creates a scatterplot with hatched patterns by using geom_segment(). Also creates the legend to represent each hatched group. The aesthetics defining each pattern, like the lineType and lineColor are all passed to geom_segment().

Usage

scatterHatch(
  data,
  x,
  y,
  color_by,
  legendTitle = "",
  pointSize = 1,
  pointAlpha = 0.5,
  gridSize = NULL,
  sparsePoints = NULL,
  patternList = NULL,
  colorPalette = NULL
)

Arguments

data	Dataset to be used
x	Column name of x-coordinates
y	Column name of y-coordinates
color_by	Column name of factor that defines groupings
legendTitle	Title of the legend
pointSize	Point size for the scatterplot
pointAlpha	Transparency of points in the scatterplot
gridSize	Controls the precision of the hatched pattern. Larger values correspond to greater precision. Default follows a exponential decay function based on point size.
sparsePoints	Logical Vector denoting points annotated as sparse. If NULL, default sparsity detector will be used to annotate sparse points.
patternList	Aesthetics to be passed for each pattern (must be a list where each element has a named pattern)
colorPalette	Colors to be used for each group. Default is color-blind friendly.

Value

ggplot2 object of scatterplot with hatched patterns for each group.

Examples

data(pdacData)
scatterHatch(pdacData, "Xt", "Yt", "frame")
