Web11. apr 2024. · I have a very simple function, that returns a data frame. The function takes three parameters, a dataset, and two variables that are present in the dataframe. I was hoping to use the map/pmap family of functions to feed a vector/list of inputs and produce a single (long) output dataset. WebThe map (.x, .f) functions transforms each element of the vector .x with the function .f, returning a vector defined by the suffix ( _lgl, _chr () etc). walk () is a variant for functions called primarily for their side-effects; it returns .x invisibly. As well as functions, .f, can take numbers and characters (used as a shorthand for ...
