is_value is a helper function for model_gamm, calc_deriv, test_interaction, and scoring. It checks whether each element is a true value and not NA, NaN, NULL or Inf when filtering tibbles for specific values. If the filtering variable (e.g. p_val or edf) contains NAs, the respective rows are usually not excluded in the requested subset or (when using the function split) excluded in both TRUE/FALSE subsets.




An R object, which should be a numeric vector.


The function returns a logical vector with TRUE or FALSE for each element of x.
