Maximum area given x and y coordinates

Source: R/hull.R

Present since hutils 1.2.0.

ahull(DT, x = DT$x, y = DT$y, minH = 0, minW = 0,
  maximize = "area", incl_negative = FALSE)

Arguments

DT, x, y

Coordinates of a curve containing a rectangle. Either as a list, DT, containing columns x and y.
minH

The minimum height of the rectangles.
minW

The minimum width of the rectangles.
maximize

How the rectangle should be selected. Currently, only "area" supported.
incl_negative

Should areas below the x-axis be considered?

Value

A data.table: The coordinates of a rectangle, from (0, 0), (1, 0), (1, 1), (0, 1), south-west clockwise, that is contained within the area of the chart for positive values only.
