 Just to confirm that I've just downloaded that and converted a grid
and read it into R.

 The download is 100Mb, and it only runs on Windows.

 After some menu hunting I loaded the grid file into Montaj viewer and
converted it to a .flt file, which read into R as a single layer
raster with decimal values the same as the original raster. The option
to save as a TIFF out of Montaj Viewer resulted in an integer raster.
