New features

Minor changes

rstatix 0.2.0 2019-09-03

Minor changes

  • get_anova_table() supports now an object of class grouped_anova_test
  • ANOVA table is now correctly returned when correction = "none" for repeated measures ANOVA
  • NAs are now automatically removed before quantile computation for identifying outliers (@IndrajeetPatil, #10).
  • Unquoted factor variable name is now supported in factor manipulation functions: set_ref_level(), reorder_levels() and make_valid_levels()
  • New argument model added in the function emmeans_test()
  • Adapting to tidyr v1.0.0 (@jennybc, #6)

New features

  • New function welch_anova_test(): Welch one-Way ANOVA test. A wrapper around the base function stats::oneway.test(). This is is an alternative to the standard one-way ANOVA in the situation where the homogeneity of variance assumption is violated.
  • New function friedman_effsize(), computes the effect size of Friedman test using the Kendall’s W value.
  • New function friedman_test(), provides a pipe-friendly framework to perform a Friedman rank sum test, which is the non-parametric alternative to the one-way repeated measures ANOVA test.
  • New function games_howell_test(): Performs Games-Howell test, which is used to compare all possible combinations of group differences when the assumption of homogeneity of variances is violated.
  • New function kruskal_effsize() for computing effect size for Kruskal-Wallis test.
  • New functions added to round and format p-values: p_round(), p_format(), p_mark_significant().
  • New function wilcox_effsize() added for computing effect size (r) for wilcoxon test.
  • New function get_anova_table() added to extract ANOVA table from anova_test() results. Can apply sphericity correction automatically in the case of within-subject (repeated measures) designs.
  • New functions added to extract information from statistical tests: get_anova_label()
  • New function emmeans_test() added for pairwise comparisons of estimated marginal means.

Minor changes

Bug fixes

  • detailed arguments correctly propagated when grouped stats are performed

rstatix 0.1.1 2019-06-20

New features

  • New function get_pvalue_position added to autocompute p-value positions for plotting significance using ggplot2.
  • New function get_comparisons() added to create a list of possible pairwise comparisons between groups.
  • New function dunn_test() added for multiple pairwise comparisons following Kruskal-Wallis test.
  • New function sign_test() added.

Minor changes

Bug fixes

  • the argument detatiled is now passed to compare_pairs().
