combine one band rasters to get a multiband raster

I have 4 one-band's rasters (same resolution, same extents...) that I want to combine to have a four-band's raster. Anyone could tell me how to do this with R? Thank you.

To create a raster stack of rasters of same extent and resolution, use the stack function in the raster package:

s  <-  stack(raster1,  raster2)

In this case the raster can be a raster object or a file path to a raster.

edit (concrete example):

library(raster)
fn  <-  system.file("external/test.grd",  package="raster")
s  <-  stack(raster(fn),  raster(fn)*2) #here i had to create the raster object since I 
#was multiplying one of the input rasters 
s

class       : RasterStack 
dimensions  : 115, 80, 9200, 2  (nrow, ncol, ncell, nlayers)
resolution  : 40, 40  (x, y)
extent      : 178400, 181600, 329400, 334000  (xmin, xmax, ymin, ymax)
coord. ref. : +init=epsg:28992
