The goal of checkstring is to provide string format validation functions for R, inspired by Zod’s string validators. It extends the checkmate family of argument checks with common string format validations such as email addresses, UUIDs, URLs, IP addresses, and financial and academic identifiers like ISIN, CUSIP, IBAN, ISBN, and ORCID, including check digit verification.
You can install the released version of checkstring from CRAN with:
