In paleolimbot/grd: Raster and Grid Geometry

Description

Collect a grid in memory

Usage

grd_collect(
  grid,
  i = NULL,
  j = NULL,
  ...,
  ptype = grd_data_ptype(grd_data(grid))
)

## Default S3 method:
grd_collect(
  grid,
  i = NULL,
  j = NULL,
  ...,
  ptype = grd_data_ptype(grd_data(grid))
)

Arguments

grid	A grd_xy(), grd_rct(), or other object implementing grd_*() methods.
i	1-based index values. i indices correspond to decreasing y values; j indices correspond to increasing x values. Values outside the range 1:nrow|ncol(data) will be censored to NA including 0 and negative values.
j	1-based index values. i indices correspond to decreasing y values; j indices correspond to increasing x values. Values outside the range 1:nrow|ncol(data) will be censored to NA including 0 and negative values.
...	Passed to subset methods
ptype	The R object type that should be used to represent the data.

Value

A grd_rct() or grd_xy()

Examples

data <- grd_data_generic(volcano, data_order = c("-y", "x"))
(grid <- grd_rct(data))
grd_collect(grid)
