How to apply the seq function in R - 5 R programming examples - R tutorial - How to generate a sequence in R - Complete code in RStudio
The basis can be created in R using function poly(x,3) with inputs x (referring to the variable), and p (referring to the degree of the polynomial). This leads to a simple univariate smooth model of the form: yi=f(xi)+ε where f() is some function/transformation of the predictor...
Rapply(Tt) Applies this function to the given argument. default <V>Function<V,R>compose(Function<? super V,? extendsT> before) Returns a composed function that first applies thebeforefunction to its input, and then applies this function to the result. ...
