round function

Integer values

These functions take a single RasterLayer argument x and change its values to integers.

ceiling returns a RasterLayer with the smallest integers not less than the corresponding values of x.

floor returns a RasterLayer with the largest integers not greater than the corresponding values of x.

trunc returns a RasterLayer with the integers formed by truncating the values in x toward 0.

round returns a RasterLayer with values rounded to the specified number of digits (decimal places; default 0). methods

Methods

• x: a RasterLayer object
• digits: integer indicating the precision to be used
• ...: additional arguments

Details

see ?base::round

Returns

a RasterLayer object

Examples

r <- raster(ncol=10, nrow=10)
values(r) <- runif(ncell(r)) * 10
s <- round(r)
