Examples

if (requireNamespace("raster", quietly = TRUE)) {
  w1 <- createWorld(minPxcor = 0, maxPxcor = 9, minPycor = 0, maxPycor = 9, data = 1:100)
  w1Ras <- world2raster(w1)
  index <- 24
  pxpy <- PxcorPycorFromCell(world = w1, cellNum = index)

  rasValue <- as.integer(unname(w1Ras[index]))
  # Not correct index:
  identical(w1[index], rasValue)

  # Correct index
  identical(w1[NLworldIndex(w1, index)], rasValue)
}
