| Two questions:
| 
| 1) these steps works; but this is the correct approach?
| 
| 2) to use Rcpp and RInside I must install only through R?  Or I can

This is a bit off-topic but as I have meant to write this up on a web page
somewhere and haven't yet here it goes: I use two scripts out of littler (a
package on Github, and in Debian/Ubuntu) _all_ _the_ _time_ because I like to
just launch builds / upgrades on a command prompt and keep my R prompt free
for actual work.

With that, you also do not need to uninstall first.  

Current versions of these scripts are at 

   https://github.com/eddelbuettel/littler/blob/master/examples/install.r

   https://github.com/eddelbuettel/littler/blob/master/examples/update.r

which I just sync'ed to what I currently use (eg RStudio's CDN as the CRAN
mirror as it is consistently very fast).

So I'd just say    'install.r RInside'   and it would fetch, build and
(re-)install that package.  You can specify more than one etc pp. 

Hth,  Dirk
