Please note: {rgdal} has now been retired from CRAN and has therefore been removed from this documentation. However, versions of {leaflet} >= 2.2.0 do not depend on this package. To avoid dependency on obsolete packages, older versions should only be installed if strictly necessary. Please try to use the most up-to-date versions wherever possible.

Geospatial R packages must be compiled and installed from source, rather than as binary files. The reason for this is that the packages need to know where the geospatial libraries are installed in the underlying Linux operating system. A simple call of the `install.packages()` function will not suffice. As such, please follow the instructions below exactly.
