sourceDirectory

Sources files recursively to either local or global environment

Description

Sources files recursively to either local or global environment.

Usage

## Default S3 method:
sourceDirectory(path, pattern=".*[.](r|R|s|S|q)([.](lnk|LNK))*$", recursive=TRUE,
  envir=parent.frame(), onError=c("error", "warning", "skip"), modifiedOnly=TRUE, ...,
  verbose=FALSE)

Arguments

`path`	A path to a directory to be sourced.
`pattern`	A regular expression file name pattern to identify source code files.
`recursive`	If `TRUE`, subdirectories are recursively sourced first, otherwise not.
`envir`	An `environment` in which the code should be evaluated.
`onError`	If an error occurs, the error may stop the job, give a warning, or silently be skipped.
`modifiedOnly`	If `TRUE`, only files that are modified since the last time they were sourced are sourced, otherwise regardless.
`...`	Additional arguments passed to `sourceTo`().
`verbose`	A `logical` or a `Verbose` object.

Value

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

Details

Subdirectories and files in each (sub-)directory are sourced in lexicographic order.

Hooks

This method does not provide hooks, but the internally used sourceTo() does.
