## S3 method for class 'raster'
plot(x, y,
     xlim = c(0, ncol(x)), ylim = c(0, nrow(x)),
     xaxs = "i", yaxs = "i",
     asp = 1, add = FALSE, ...)

Arguments

x, y	raster. y will be ignored.
xlim, ylim	Limits on the plot region (default from dimensions of the raster).
xaxs, yaxs	Axis interval calculation style (default means that raster fills plot region).

add	Logical indicating whether to simply add raster to an existing plot.
...	Further arguments to the rasterImage function.

require(grDevices)
r <- as.raster(c(0.5, 1, 0.5))
plot(r)
# additional arguments to rasterImage()
plot(r, interpolate=FALSE)
# distort
plot(r, asp=NA)
# fill page
op <- par(mar=rep(0, 4))
plot(r, asp=NA)
par(op)
# normal annotations work
plot(r, asp=NA)
box()
title(main="This is my raster")
# add to existing plot
plot(1)
plot(r, add=TRUE)
