dirApply: Apply a function over files in directory.
In PolMine/ctk: Toolkit for Preparing Corpora

The function (f) will be applied to the files in a directory (in a lapply/sapply/vapply-style).

dirApply(f, sourceDir, targetDir = NULL, pattern = NULL, mc = FALSE,
  progress = TRUE, verbose = FALSE, sample = FALSE, filenames = NULL,
  continue = FALSE, failsafe = FALSE, param = list())

`f`	function that will be applied to all files in sourceDir
`sourceDir`	source directory with files to be processed
`targetDir`	target directory where the processed files will be saved
`pattern`	pattern (can be a regex) that will be used by `list.files` as 'pattern'-argument
`mc`	logical, whether to use multicore/parallel processing, if numeric, the number of cores to use
`progress`	logical, whether to show progress bar
`verbose`	logical, whether to be verbose
`sample`	defults to FALSE, if a numeric, a number of random files to process
`filenames`	character vector with filenames to be used, a subset of files in `sourceDir`
`continue`	work only on those files not yet present in target dir
`failsafe`	whether to be robust and catch errors using `try`, available only without parallelisation
`param`	a list with parameters to be passed to the function f

Function f passes in a function that will be applied to the individual files in the source directory (sourceDir). The function needs to conform to a standardized format, parameters required are "filename" (character), "sourceDir" (character), "targetDir" (character) and "param" (list).

The function f can be applied in a multicore mode. If progress is FALSE, then mclapply will be used. If progress is TRUE, pblapply from the package pbapply will be used.
