px2ppp: Convert pixel coordinates to PPP object

In ClairBee/IO.Pixels: Functions for analysis of distribution of dead pixels (part of Inside Out project).

Description

Convert coordinates from bad pixel map to a PPP object for spatial analysis. The resulting image can be further cropped if necessary.

Usage

px2ppp(px, im.dim = c(2048, 2048), crop = list(c(1, im.dim[1]), c(1,
  im.dim[2])))

Arguments

px	data.frame or matrix, the first two columns of which contain the X and Y coordinates of points to be marked on the raster
im.dim	Vector of dimensions for the final raster. Default is c(2048, 2048).
crop	List of two vectors of crop boundaries. Default is list(c(1, im.dim[1]), c(1, im.dim[2])), which crops to original image area.

Value

ppp object of the required dimensions
