In addition to using Adam's suggestions, you can also have a look at the
example in the raster::hillShade function:

dem <- getData('alt', country='CHE')
slas <- slopeAspect(dem)
hill <- hillShade(slas[[1]], slas[[2]], 40, 270)
plot(hill, col=grey(0:100/100), legend=FALSE, main='Switzerland')
plot(dem, col=rainbow(25, alpha=0.35), add=TRUE)
