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)
