RcppAPT 0.0.1

Over the last few days I put together a new package RcppAPT which interfaces the C++ library behind the awesome apt, apt-get, apt-cache, … commands and their GUI-based brethren.

The package currently implements two functions which permit search for package information via a regular expression, as well as a (vectorised) package name-based check. More to come, and contributions would be very welcome.

A few examples just to illustrate follow.

R> hasPackages(c("r-cran-rcpp", "r-cran-rcppapt"))
   r-cran-rcpp r-cran-rcppapt 
          TRUE          FALSE 

This shows that Rcpp is (of course) available as a binary, but this (very new) package is (unsurprisingly) not yet available pre-built.

We can search by regular expression:

R> library(RcppAPT)
R> getPackages("^r-base-c.")
          Package      Installed       Section
1 r-base-core-dbg 3.1.2-1utopic0 universe/math
2 r-base-core-dbg           <NA> universe/math
3     r-base-core 3.1.2-1utopic0 universe/math
4     r-base-core           <NA> universe/math
R> 

With the (default) expression catching everything, we see a lot of packages:

R> dim(getPackages())
[1] 104431      3
R> 

A bit more information is on the package page here as well as as the GitHub repo.
