as_FD.data.frame: Convert data.frame to FDboost data format

In Almond-S/manifoldboost: Boosting Regression Models for Manifold Valued Data

Convert data.frame to FDboost data format

Description

Convert data.frame to FDboost data format

Usage

## S3 method for class 'data.frame'
as_FD(x, obj.formula, ...)

Arguments

x	a data.frame including the response values, functional response arguments, dimension indicator for multidimensional response functions and an id column indicating the curve id
obj.formula	a formula of the form value^dim ~ arg | id indicating the respective columns of x. Missing ^dim or |id are interpreted as only one dimension/id occuring in the data.
...	additional arguments to be passed to or from methods.

Details

A data.frame will basically directly passed to FDboost without much further transformation. In principle, only the id-column is replaced by a numeric vector ranging from 1 to length(unique(id)), and the dim-colum is converted to factor.

Value

a data.frame in 'irregular' FDboost format FD_irregular.
