[Qgis-user] Empty Results in R

[Alex Mandel]

Ah, that makes sense. R on linux compiles any included C or Fortran so
you need the development libraries and R does not handle this automatically.

For others facing this issue, this likely takes care of it.
sudo apt-get install build-essential
sudo apt-get build-dep gdal-bin

If you had been directly in R the error on the build would have said
what lib was missing.

Enjoy,
Alex
