fc.check: Check fiscal codes

In ifctools: Italian fiscal code miscellaneous utilities

Description

The function performs fiscal codes (both temporary and definitive) check, computing the last (control) character basing on the others. The algorithm is intended to be quite "draconian", so you'll better make some precleaning (remove blank spaces and upcase) if needed. See examples.

Usage

fc.check(fc)

Arguments

fc	A character vector of fiscal codes.

Value

The function return TRUE if the fiscal code is wrong, FALSE otherwise.

Examples

## As i've said, the algo is quite draconian. Consider the code
## "QWEASD34D12H221M" (fictitious but right). I would like
## "qWeASd34D12h 221M   " to be (and it's) TRUE, because i consider it
## as an error (it's diminishing match probability).

fc.check("qWeASd34D12h 221M   ") 

## So you'll betted do pre-cleaning (upcase and blank trimming)

fc <- c("qWeASd34D12h 221M   ", "12312312312")
fc <- gsub(" ","", toupper(fc))
fc.check(fc)
