Extract the per patient polynomial Coefficients of a feature trayectory

Description

Given a longituinal data set, it will extract the associated polynomial coefficients for each sample.

Usage

	trajectoriesPolyFeatures(data,
                              feature="v1", 
                              degree=2, 
                              time="t", 
                              group="ID",
                              timeOffset=0,
                              strata=NULL,
                              plot=TRUE,
                              ...)

Arguments

data	The dataframe
feature	The name of the outcome
degree	The fitting function used to model the data
time	The percentage of the data to be used for training
group	The number of times that the CV process will be repeated
timeOffset	The time offset
