The final data sets can represent data from randomized control trials, repeated measure (longitudinal) designs, … WebbThere are three functions that facilitate this: viewBasis, viewSplines, and genSpline. The first two functions are more exploratory in nature, and just provide plots of the B-spline basis functions and the splines, respectively. The third function actually generates data and adds to an existing data.table.
