as.character: Character representation of a Raster or Extent object

In raster: Geographic Data Analysis and Modeling

Description

as.character returns a text (R code) representation of a Raster* or Extent object. The main purpose of this is to allow quick generation of objects to use in examples on, for example, stackoverflow.com.

Usage

## S4 method for signature 'Raster'
as.character(x, ...)
## S4 method for signature 'Extent'
as.character(x, ...)

Arguments

x	Raster* or Extent object
...	additional arguments, none implemented

Value

character

Examples

r <- raster(ncol=3, nrow=3)
values(r) <- 1:ncell(r)
as.character(r)
s <- stack(r, r)
as.character(s)
as.character(extent(s))

x <- as.character(s)
eval(parse(text=x))

y <- as.character(extent(s))
eval(parse(text=y))
