In qdapRegex: Regular Expression Removal, Extraction, and Replacement Tools

Boundary Wrap (Bind) and 'or' Concatenate Elements

Description

A wrapper for bind and pastex that wraps each sub-expression element with left/right boundaries (\b by default) and then concatenate/joins bound strings with a regex 'or' ("|"). Equivalent to pastex(bind(...), sep = "|").

Usage

bind_or(..., group.all = TRUE, left = "\\b", right = left)

Arguments

group.all	logical. If TRUE the resulting 'or' concatenated elements will be wrapped with grouping parenthesis.
left	A single length character vector to use as the left bound.
right	A single length character vector to use as the right bound.
...	Regular expressions to paste together or a named expression from the default regular expression dictionary prefixed with single at (@) (e.g., "@rm_hash") or a regular expression from regex_supplement dictionary prefixed with an at (@) (e.g., "@time_12_hours").

Examples

bind_or(LETTERS)
bind_or("them", "those", "that", "these")
bind_or("them", "those", "that", "these", group.all = FALSE)
