calculus (version 0.2.0)

wrap: Wrap Character

Description

Wraps characters in round brackets.

Usage

wrap(x)

Arguments

x

characters

Value

wrapped characters.

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).

Examples

# NOT RUN {
# wrap characters
wrap('a+b')

# wrap array of characters
wrap(array(letters[1:9], dim = c(3,3)))

# }
