In Teri934/scattermore2: Scatterplots with More Points

scatter_points_rgbwt

Description

Colorize given data with one given color or each point has its corresponding given color.

Usage

scatter_points_rgbwt(
  xy,
  xlim = c(min(xy[, 1]), max(xy[, 1])),
  ylim = c(min(xy[, 2]), max(xy[, 2])),
  out_size = c(512, 512),
  RGBA = c(0, 0, 0, 255),
  map = NULL,
  palette = NULL
)

Arguments

xy	2-column float matrix with point coordinates. As usual with rasters in R, X axis grows right, and Y axis grows DOWN. Flipping ylim causes the "usual" mathematical behavior.
xlim	Float limits as usual (position of the first pixel on the left/top, and the last pixel on the right/bottom), 2-element vector. You can easily flip the top/bottom to the "usual" mathematical system by flipping the ylim vector.
ylim	Float limits as usual (position of the first pixel on the left/top, and the last pixel on the right/bottom), 2-element vector. You can easily flip the top/bottom to the "usual" mathematical system by flipping the ylim vector.
out_size	2-element vector, integer size of the result histogram, defaults to c(512,512).
RGBA	Integer vector with 4 elements or matrix or array (4xn dim, n >= 2, n ~ xy rows) with R, G, B and alpha channels in integers, defaults to c(0,0,0,255).
map	Integer vector with indices to palette.
palette	Matrix or array (4xn dim, n >= 2, n ~ xy rows) with R, G, B and alpha channels in integers.

Value

Float RGBWT matrix.
