# S3 method for fdm
residuals(object,...)
# S3 method for lca
residuals(object,...)
# S3 method for fdm
fitted(object,...)
# S3 method for lca

residuals.fdm and residuals.lca produce an object of class “fmres” containing the residuals from the model.

fitted.fdm and fitted.lca produce an object of class “fts” containing the fitted values from the model.
