the name of an object or a regular expression.
what can be either a name or a character string; however, we recommend a character string for compatibility. |
where | a logical value. If TRUE, the names of the returned vector has the position of the package (in search()) that contains the object. The default is FALSE. |
ignore.case | a logical value. If TRUE (the default), uppercase and lowercase characters are considered equivalent when matching. |
mode | a character string. If it is not the default ("any"), only objects whose mode is mode are considered. |
