Examples

wgs84()
# CRS arguments: +init=epsg:4326
wgs84(TRUE)
# CRS arguments: +init=epsg:3395

# create a raster
r <- raster(nrows = 10, ncols = 10,
              xmn = 0, xmx = 10)
# by default wgs84
projection(r)
# [1] "+proj=longlat +datum=WGS84"

# change it to projected (not that you'd want to do this i.r.l.)
projection(r) <- wgs84(TRUE)
projection(r)
#[1] "+init=epsg:3395"
