clearCache

A <code><a rd-options="base" href="/link/character?package=R.cache&version=0.14.0&to=base" data-mini-rdoc="base::character">character</a></code> string specifying the directory to be cleared.
 By default, the path is what is returned by <code><a rd-options="" href="/link/getCachePath?package=R.cache&version=0.14.0" data-mini-rdoc="R.cache::getCachePath">getCachePath</a></code>()
 which arguments <code>...</code> are also passed.

path

Arguments passed to <code><a rd-options="" href="/link/getCachePath?package=R.cache&version=0.14.0" data-mini-rdoc="R.cache::getCachePath">getCachePath</a></code>(), especially
 argument <code>dirs</code> to specify subdirectories.

If <code><a rd-options="base:logical" href="/link/TRUE?package=R.cache&version=0.14.0&to=base%3Alogical" data-mini-rdoc="base:logical::TRUE">TRUE</a></code>, subdirectories are also removed, otherwise
 just the files in the specified directory.

recursive

If <code><a rd-options="base:logical" href="/link/TRUE?package=R.cache&version=0.14.0&to=base%3Alogical" data-mini-rdoc="base:logical::TRUE">TRUE</a></code>, the user will be prompted to confirm that
 the directory will cleared before files are removed.

prompt

Removes all files in a cache file directory.

programming

Memoization can be used to speed up repetitive and computational expensive function calls.  The first time a function that implements memoization is called the results are stored in a cache memory.  The next time the function is called with the same set of parameters, the results are momentarily retrieved from the cache avoiding repeating the calculations.  With this package, any R object can be cached in a key-value storage where the key can be an arbitrary set of R objects.  The cache memory is persistent (on the file system).
