INLA will be used. *** inla.core.safe: The inla program failed, but will rerun in case better initial values may help. try=1/1 Error in inla.core.safe(formula = formula, family = family, contrasts = contrasts, : In f(spaceid): 'covariate' must match 'values', and both must either be 'numeric', or 'factor'/'character'.
