mutator - Mutation Testing

Performs mutation testing for 'R' packages to assess the effectiveness of a test suite. It mutates source files, runs package tests against each mutant, and reports which mutants were killed, survived, or timed out. Parallel execution is supported for larger code bases. The optional 'imputesrcref' package, available from <https://github.com/PRL-PRG/imputesrcref>, improves source locations when installed.

contractr - Run-Time Type Contracts for R Functions

Attaches run-time type contracts to R functions. A function is annotated with a type declaration written in the 'tastr' type language; contractr injects assertions that check the arguments and the return value against the declared type on every call, signalling a warning or an error (depending on the configured severity) when a value does not conform.
