### Usage

    find(what, mode = "any", numeric = FALSE, simple.words = TRUE)

### Arguments

what | the name of an object, or, if simple.words = TRUE, a regular expression. what can be either a name or a character string; however, a character string is recommended for compatibility.
mode | a character string. If it is not the default ("any"), only objects whose mode is mode are considered.
numeric | a logical value. If numeric = TRUE, it returns the position in search() list. Otherwise, it returns the name of the package.
simple.words | a logical value. If TRUE (the default), the what object names must match what exactly. If FALSE, what is treated as a regular expression.

Value

- If numeric = FALSE (the default), returns a character vector of names of packages that contain what.
- If numeric = TRUE, returns a numeric vector of positions (in search()) of packages that contain what. The names of the vector contains the corresponding package name.
