title: convert raster from coarse to finer resolution
body: <p>This is my raster properties:</p>
  <pre><code>class      : RasterLayer 
  dimensions : 3001, 3000, 9003000  (nrow, ncol, ncell)
  resolution : 0.12, 0.034  (x, y)
  extent     : -180, 180, -40.034, 62  (xmin, xmax, ymin, ymax)
  crs        : +proj=longlat +datum=WGS84 +no_defs 
  source     : test.tif 
  names      : test
  </code></pre>
  <p>I want to convert this into a raster with a resolution of 0.008333333 in both x and y direction</p>
  <pre><code>library(raster)
  tar_res &lt;- 0.008333333
  disagg_raster &lt;- disaggregate(my_raster, 
                                fact = c(res(my_raster)[1]/tar_res, res(my_raster)[2]/tar_res))
  
  disagg_raster
  class      : RasterLayer 
  dimensions : 12004, 42000, 504168000  (nrow, ncol, ncell)
  resolution : 0.008571429, 0.0085  (x, y)
  extent     : -180, 180, -40.034, 62  (xmin, xmax, ymin, ymax)
  crs        : +proj=longlat +datum=WGS84 +no_defs 
  </code></pre>
  <p>How do I get the resolution to be 0.008333333 in both x and y direction?</p>
