New features Implement a plot method for path_coeff_*() functions. New function path_coeff_seq() to implement a sequential (two chains) path analysis. New function prop_na() to measure the proportion of NAs in each column. New functions remove_cols_all_na() and remove_rows_all_na() to remove columns and rows that have all values as NAs. New functions ci_mean_z() and ci_mean_t() to compute z- and t-confidence intervals, respectively. New function set_wd_here() to set the working directory to the path of the current script. Minor improvements Fix bug in rowname_to_column(). Fix bug in mps() where stab was being rewritten with stab_res. Changes the object name in mgidi() example that overwrites the function. Fix bug with x.lab and y.lab from plot_scores(). Now it accepts an object from expression() plot_waasby() now accepts objects of class waas_means. get_model_data() now includes new options coefs, and anova for objects computed with ge_reg(). New argument max_overlaps in plot_scores() to exclude text labels that overlap too many things. Improve the control over highlighted individuals in plot_scores() (shape, alpha, color, and size).
