flip(x, direction='y', filename='', ...)

## S4 method for signature 'RasterStackBrick'
flip(x, direction='y', filename='', ...)

Arguments

x

Raster* object

direction

Character. 'y' or 'x'; or 1 (=x) or 2 (=y)

r <- raster(nrow=18, ncol=36)
m <- matrix(1:ncell(r), nrow=18)
values(r) <- as.vector(t(m))
rx <- flip(r, direction='x')
values(r) <- as.vector(m)
