Examples

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)
#> [1] FALSE

# Correct index
identical(w1[NLworldIndex(w1, index)], rasValue)
#> [1] TRUE
