%description
A set of functions allowing to implement the 'SpiceFP' approach which is
iterative. It involves transformation of functional predictors into
several candidate explanatory matrices (based on contingency tables), to
which relative edge matrices with contiguity constraints are associated.
Generalized Fused Lasso regression are performed in order to identify the
best candidate matrix, the best class intervals and related coefficients
at each iteration. The approach is stopped when the maximal number of
iterations is reached or when retained coefficients are zeros.
Supplementary functions allow to get coefficients of any candidate matrix
or mean of coefficients of many candidates. The methods in this package
are describing in Girault Gnanguenon Guesse, Patrice Loisel, Bénedicte
Fontez, Thierry Simonneau, Nadine Hilgert (2021) "An exploratory penalized
regression to identify combined effects of functional variables
