### Usage

    RSiteSearch(string,
                restrict = c("Rhelp02a", "functions", "docs"),
                format = "normal", sortby = "score",
                matchesPerPage = 20)

### Arguments

`string` | word(s) or phrase to search. If the words are to be searched as one entity, enclose all words in braces (see example).
`restrict` | character: What areas to search in: `Rhelp02a` for R-help mailing list archive since 2002, `Rhelp01` for mailing list archive before 2002, `docs` for R manuals, `functions` for help pages. Use `c()` to specify more than one.
`format` | `normal` or `short` (no excerpts).
`sortby` | How to sort the search results (`score`, `date:late` for sorting by date with latest results first, `date:early` for earliest first, `subject` for subject in alphabetical order, `subject:descending` for reverse alphabetical order, `from` or `from:descending` for sender (when applicable), `size` or `size:descending` for size.)
`matchesPerPage` | How many items to show per page.

Unique partial matches will work for all arguments. Each new browser window will stay open unless you close it.
