getPackages: Retrieve Names of All Installable Packages
Description
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.
Usage
getPackages(regexp = ".")
Arguments
regexp
A regular expression for the package name(s) with a
default of all (".").
Value
A data frame with columns containing the
package name, the installed version (or NA if not installed)
and the section it is installed in (or NA).
Details
Note that the package lookup uses regular expressions. If only a
single package is desired, append a single $ to terminate
the expression. Ier-cran-rcpp$ will not
return results for r-cran-rcpparmadillo and
r-cran-rcppeigen.
