Updated version

[stephaneguerrier]

• [ ] Add spatial functions (see folder spatial-to-fix)
• [ ] Put uml somewhere else?
• [ ] Function robust_eda there is a problem with the help (see examples)
• [ ] Do we need to export compare_wvar_split and compare_wvar_no_split?
• [ ] The functions wccv_pair, wccv and plot.wccv_pair should be improved and checked
• [ ] Do we need to export wccv_get_y?
• [ ] The functions av_ar1, av_wn, plot.auto_corr and ACF can probably be removed (should not be used and already in avar).
• [ ] The C++ functions arma_to_wv, acf_sum, arma_to_wv_app, arma11_to_wv, ar1_to_wv, ma1_to_wv, qn_to_wv, rw_to_wv. dr_to_wv, theoretical_wv, decomp_theoretical_wv, decomp_to_theo_wv can probably be removed (should not be used and already in gmwm).
• [ ] Check if the C++ functions seq_cpp, seq_len_cpp, quantile_cpp, diff_cpp, cfilter, rfilter, expand_grid_red, dft_acf, mean_diff, num_rep. intgr_vec, diff_inv_values, diff_inv and sweep_col_mean are needed.
• [ ] The C++ function ARMAtoMA_cpp ARMAacf_cpp, acf, sarma_objdesc, sarma_calculate_spadding, sarma_components, sarma_params_construct, sarma_expand_unguided and sarma_expand probably be removed (should not be used and already in simts).
• [ ] The C++ functions sp_modwt_cpp and sp_hfilter are (probably) not used. See previous point on spatial functions.
• [ ] What is the C++ function compute_cov_cpp doing? There is no documentation
