Split the convex hull in four parts along two input lines

Description

This function splits the convex hull in two parts along a vertical and a horizontal line.

Usage

splitHull(
  p,
  pointsDF,
  hullSegments,
  xInt = NULL,
  yInt = NULL,
  lineColor = "navy",
  lineWidth = 0.3,
  lineType = c("dashed", "solid", "dotted", "dotdash", "longdash", "twodash"),
  legendLabs = paste0("Group ", seq(4)),
  alpha = 0.2
)

Arguments

`p`	A ggplot object representing the hull.
`pointsDF`	A data frame with the x and y coordinates of the points.
`hullSegments`	Data frame of segments that define the convex hull.
`xInt`	The coordinate where the vertical line intersects the x axis.
`yInt`	The coordinate where the horizontal line intersects the y axis.
`lineColor`	The color of the horizontal and vertical dividing lines, if provided. If `NULL`, no dividing lines will be drawn, though the hull will still be split along these lines if `xInt` and/or `yInt`are not `NULL`.
`lineWidth`	The width of the horizontal and vertical dividing lines. Ignored if `lineColor` is `NULL`.
`lineType`	The type of the horizontal and vertical dividing lines. Choose between 'dashed','solid', 'dotted', 'dotdash', 'longdash' and 'twodash'. Default is 'dashed'. Ignored if `lineColor` is `NULL`.
`legendLabs`	Legend labels.
`alpha`	Opaqueness level.
