Turn a grid into a matrix

The values as a matrix, one row per grid row, with the top row of the grid first. This is the arrangement image() and raster both think in, and it is where most orientation bugs come from, so it gets its own function.

Usage

# S3 method for class 'guerrilla_grid'
as.matrix(x, ...)

Arguments

x

a guerrilla_grid

...

ignored

Value

A matrix with nrow rows and ncol columns.

Examples

g <- grid_spec(dimension = c(3, 2), extent = c(0, 3, 0, 2))
g$values <- 1:6
as.matrix(g)
#>      [,1] [,2] [,3]
#> [1,]    1    2    3
#> [2,]    4    5    6
