getPackages | R Documentation |
The APT Package Management system uses a data-rich caching structure. This accessor function returns the names of installable packages for a given regular expression.
getPackages(regexp = ".")
regexp |
A regular expression for the package name(s) with a default of all ("."). |
Note that the package lookup uses regular expressions. If only a
single package is desired, append a single $
to terminate
the expression. Ie r-cran-rcpp$
will not
return results for r-cran-rcpparmadillo
and
r-cran-rcppeigen
.
A data frame with columns containing the package name and version (or NA if unavailable).
