field_format {validate} | R Documentation

## Check whether a field conforms to a regular expression

### Description

A convenience wrapper around `grepl` to make rule sets more readable.

### Usage

    field_format(x, pattern, type = c("glob", "regex"), ...)

### Arguments

`x` | Bare (unquoted) name of a variable. Otherwise a vector of class `character`. Coerced to character as necessary.
`pattern` | `[character]` a regular expression
`type` | `[character]` How to interpret `pattern`. In globbing, the asterisk (‘*') is used as a wildcard that stands for ’zero or more characters'.
`...` | passed to grepl
