comment How to select a Subset of PolySet data in R?
I can't get the code to run... can you post some straightforward instructions on how to get "Bhutan's administrative area" so I can duplicate your "df" ?

comment R: Download a large DEM, change projection, and adjust to smaller scale
I let Robert Hijmans know about the case. On a smaller DEM, the default settings are near-optimal, so this is a mystery so far.

This R function is designed to use GDAL, but seems not to be using it well in this case. My question is "How can I best accomplish this task with R", not "What GIS software is available that can do this task."

That didn't do it, but this did: setOptions(chunksize = 1e+04, maxmemory = 1e+06) Time eight minutes, much less than it would take to install and use a real GIS.
