R: Check input value

check.input.value {rapport} | R Documentation

## Check input value

### Description

A bit misleading title/function name - it validates input values, according to rules set in general input attributes (`length`) or class-specific ones (`nchar`, `nlevels` or `limit`).

### Usage

    check.input.value(input, value = NULL, attribute.name = c("length", "nchar",
      "nlevels", "limit"))

### Arguments

`input` | input item
`value` | input value, either template-defined, or set by the user
`attribute.name` | input attributes containing validation rules (defaults to `length`)
