findFiles

Finds one or several files in multiple directories

Finds one or several files in multiple directories.

## Default S3 method:
findFiles(pattern=NULL, paths=NULL, recursive=FALSE, firstOnly=TRUE, allFiles=TRUE, ...)

`pattern`	A regular expression file name pattern to match.
`paths`	A `character` `vector` of paths to be searched.
`recursive`	If `TRUE`, subdirectories are recursively processed, and not if `FALSE`. Alternatively, the maximum recursive depth can be specified as a non-negative `numeric`, where `FALSE` corresponds to `0L` depth and `TRUE` corresponds `+Inf` depth.
`firstOnly`	If `TRUE`, the method returns as soon as a matching file is found, otherwise not.
`allFiles`	If `FALSE`, files and directories starting with a period will be skipped, otherwise not.
`...`	Arguments passed to `list.files`().

Returns a vector of the full pathnames of the files found.

The paths argument may also contain paths specified as semi-colon (";") separated paths, e.g. "/usr/;usr/bin/;.;".

Recursive searching of directory structure is done breath-first in a lexicographic order.

Windows Shortcut links (*.lnk) are recognized and can be used to imitate links to directories elsewhere. For more details, see filePath().
