Extract Part of a String

Extract a part of a string, defined as regular expression.

StrExtract(x, pattern)

`x`	a character vector where matches are sought, or an object which can be coerced by `as.character` to a character vector.
`pattern`	character string containing a regular expression (or character string for `fixed = TRUE`) to be matched in the given character vector. Coerced by `as.character` to a character string if possible. If a character vector of length 2 or more is supplied, the first element is used with a warning. Missing values are not allowed.

The function wraps regexpr and regmatches.

A character vector.
