Overview of selection features Tidyverse selections implement a dialect of R where operators make it easy to select variables: : for selecting a range of consecutive variables. ! for taking the complement of a set of variables. & ... | |

| | | Getting the name of a type in C++ is a hassle. For something that should be trivially known by the compiler at compile-time, the closest thing we have to getting the type in a cross-platform way is to use std::type_info::name which is neither at compile-time, nor is it guaranteed to be human-readable. In fact, both GCC and Clang actually return the compiler's mangled name rather than the human-readable name we are used to. Let's try to make something better using the modern utilities from c++17 and a little creative problem solving! | ||
