Hi

This looks really nice. Thanks.

Just tried the examples on https://github.com/jannes-m/RQGIS on OS X El
Capitan with QGIS 2-8 installed using homebrew ant they worked after
specifying the path to root. But there is an error in the RQGIS usage
site:

It states:

,----
| If you are running RQGIS under Linux or on a Mac, set_env assumes that
| your root path is "/usr" and "/applications/QGIS.app/Contents",
| respectively.
`----

1) The path should be changed to "Applications" instead of
"applications" as the capital A is used in OS X. It normally does not
make a difference, but does not follow conventions.

2) The path (specified in root=...) most not contain "/Contents" but
only the path to the .app folder.

In general, it would be nice if a cal to set_env() could have some
logic to also identify homebrew installesd versions of QGIS.


Thanks,

Rainer
