Learn R Programming

sicher

sicher (German for safe or certain) is an R package that brings runtime type safety to R programming, inspired by TypeScript for JavaScript. Declare types for your variables and have them enforced automatically on every assignment, catching type errors early and making your code more robust and self-documenting.
