This heatmap provides a number of extensions to the standard R heatmap …

WebOne of the big differences between map2() and the simple function above is that map2() recycles its inputs to make sure that they're the same length: In other words, map2(x, y, f) will automatically behave like map(x, f, y) when needed. This is helpful when writing functions; in scripts you'd generally just use the simpler form directly. 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.
