Compute X and Y Coordinates for Hexagon Cells

Computes x and y coordinates from hexagon cell id's.

Usage

hcell2xy(hbin, check.erosion = TRUE)

Arguments

hbin

a object of class "hexbin", typically produced by hexbin(*).

check.erosion

logical indicating if only the eroded points should be returned in the case where hbin inherits from "erodebin" (see erodebin-class); is TRUE by default.

Value

A list with two components of the same length as bin$cell,

x

y

Details

The hexbin object hbin contains all the needed information. The purpose of this function is to reduce storage. The cost is additional calculation.

Examples

x <- rnorm(10000)
y <- rnorm(10000)
plot(x,y, pch=".")
hbin <- hexbin(x,y)
str(xys <- hcell2xy(hbin))
#> List of 2
#>  $ x: num [1:526] -0.376 0.895 -1.265 -0.884 -0.122 ...
#>  $ y: num [1:526] -3.74 -3.74 -3.5 -3.26 -3.26 ...
points(xys, cex=1.5, col=2) ; title("hcell2xy( hexbin(..) )", col.main=2)
