patchCode: Patches installed and loaded packages and more

Usage

## S3 method for class 'default}(paths=NULL, recursive=TRUE, suppressWarnings=TRUE, knownExtensions=c("R", "r", "S", "s"), verbose=FALSE, ...)':
patchCodeundefined

 Patches installed and loaded packages and more.

 paths{The path to the directory (and subdirectories) which
      contains source code that will patch loaded packages.
      If NULL, the patch path is given by the option R_PATCHES,
      If the latter is not set, the system environment with the same name
      is used. If neither is given, then ~/R-patches/ is used.}
   recursive{If TRUE, source code in subdirectories will also
      get loaded. }
   suppressWarnings{If TRUE, warnings will be suppressed,
      otherwise not.}
   knownExtensions{A character vector of filename extensions
      used to identify source code files. All other files are ignored.}
   verbose{If TRUE, extra information is printed while patching,
      otherwise not.}
   ...{Not used.}

 Returns (invisibly) the number of files sourced.

 The method will look for source code files (recursively or not) that
   match known filename extensions. Each found source code file is
   then source()d.

   If the search is recursive, subdirectories are entered if and only if
   either (1) the name of the subdirectory is the same as a loaded
   (and installed) package, or (2) if there is no installed package
   with that name. The latter allows common code to be organized in
   directories although it is still not assigned to packages.

   Each of the directories given by argument paths will be
   processed one by one. This makes it possible to have more than one
   file tree containing patches.

   To set an options, see options(). To set a system
   environment, see Sys.setenv().
   The character ; is interpreted as a separator. Due to
   incompatibility with Windows pathnames, : is not a
   valid separator.
