Wrap Characters in Parentheses

Description

Wraps characters in round brackets.

Usage

wrap(x)

Arguments

x	character.

Details

Characters are automatically wrapped when performing basic symbolic operations to prevent unwanted results. E.g.:

a+b * c+d

instead of

(a+b) * (c+d)

To disable this behaviour run options(calculus.auto.wrap = FALSE).

Value

character.
