title: Combining raster stacks
body: <p>I have multiple raster stacks containing temperature data from CRU TS 3.23 </p>
  
  <p>I have read in the files as follows: </p>
  
  <pre><code>nc = stack("cru_ts3.23.1951.1960.pre.dat.nc", varname = "pre")
  nc2 = stack("cru_ts3.23.1961.1970.pre.dat.nc", varname = "pre")
  ...
  nc7 = stack("cru_ts3.23.2011.2014.pre.dat.nc", varname = "pre")
  </code></pre>
  
  <p>Is there any way I can combine all these rasters to create one big one? I am looking at precipitation trends, so much easier to do when they're all in one object! Thanks</p>
