emmeans_test()
: restoring grouping variable class (factor
) in the final results emmeans_test()
(#169)emmeans_test()
: “Use of .data in tidyselect expressions was deprecated in tidyselect 1.2.0.”cor_plot()
now accepts additional arguments to pass to corrplot() (#66)car::Anova()
.get_comparisons()
now drops unused levels before creating possible comparisons (#67)get_summary_stats()
keeps the order of columns specified by the user (#46).two_sample_test()
now counts group sizes (n1
and n2
) by the number of non-NA
values #104
shapiro_test()
function. Shapiro_test() throws an error if the input data contains column names “value” or “variable”. This is fixed now (#52).cor_test()
function, where there was a tidy evaluation conflict when the input data contains “x” and “y” as column names (#68).dunn_test()
documentation is updated to describe the discrepancy between the default behavior of the rstatix::dunn_test()
compared to other packages (dunn.test
and jamovi
). The default of the rstatix::dunn_test() function is to perform a two-sided Dunn test like the well known commercial softwares, such as SPSS and GraphPad. This is not the case for some other R packages (dunn.test and jamovi), where the default is to perform one-sided test (#50).get_summary_stats()
handles the user defined probabilities for grouped data (#78)get_n()
to extract sample count (n) from statistical test results. - get_description
to extract stat test description or name - remove_ns()
to remove non-significant rows.add_x_position()
to better support different situations (#73).dunn_test()
include estimate1
and estimate2
when the argument detailed = TRUE
is specified. The estimate1
and estimate2
values represent the mean rank values of the two groups being compared, respectively (#59).cor_spread()
doc updated, error is explicitly shown if the input data doesn’t contain the columns “var1”, “var2” and “cor” (#95)emmeans_test()
and levene_test()
to adapt to broom release 0.7.4 (#89)anova_test()
is updated to explain the internal contrast setting (#74).p_mark_significance()
works when all p-values are NA. Empty character ("") is returned for NA (#64).rstatix
and grouped_anova_test
) added to grouped ANOVA test (#61)scales
added in the function get_y_position()
. If the specified value is “free” or “free_y”, then the step increase of y positions will be calculated by plot panels. Note that, using “free” or “free_y” gives the same result. A global step increase is computed when scales = “fixed” (#56).anova_test()
computes now repeated measures ANOVA without error when unused columns are present in the input data frame (#55)stack
added in get_y_position()
to compute p-values y position for stacked bar plots (#48).wilcox_test()
: Now, if detailed = TRUE
, an estimate of the location parameter (Only present if argument detailed = TRUE). This corresponds to the pseudomedian (for one-sample case) or to the difference of the location parameter (for two-samples case) (#45).anova_test()
function: Changing R default contrast setting (contr.treatment
) into orthogonal contrasts (contr.sum
) to have comparable results to SPSS when users define the model using formula (@benediktclaus, #40).type = "quantile"
of get_summary_stats()
works properly (@Boyoron, #39).rstatix
and the ggpubr
package and makes it easy to program with tidyverse packages using non standard evaluation. - df_select - df_arrange - df_group_by - df_nest_by - df_split_by - df_unite - df_get_var_names - df_label_both - df_label_valuefreq_table()
the option na.rm
removes only missing values in the variables used to create the frequency table (@JuhlinF, #25).anova_test()
(@benediktclaus, #31)games_howell_test()
function : the t-statistic is now calculated using the absolute mean difference between groups (@GegznaV, #37).cohens_d()
function now supports Hedge’s correction. New argument hedge.correction
added . logical indicating whether apply the Hedges correction by multiplying the usual value of Cohen’s d by (N-3)/(N-2.25)
(for unpaired t-test) and by (n1-2)/(n1-1.25)
for paired t-test; where N is the total size of the two groups being compared (N = n1 + n2) (@IndrajeetPatil, #9).cohens_d()
outputs values with directionality. The absolute value is no longer returned. It can now be positive or negative depending on the data (@narunpat, #9).mu
is now considered when calculating cohens_d()
for one sample t-test (@mllewis, #22).tukey_hsd()
now handles situation where minus -
symbols are present in factor levels (@IndrajeetPatil, #19).identify_outliers
returns a basic data frame instead of tibble when nrow = 0 (for nice printing)detailed
added in dunn_test()
. If TRUE, then estimate and method columns are shown in the results.prop_test()
, pairwise_prop_test()
and row_wise_prop_test()
. Performs one-sample and two-samples z-test of proportions. Wrappers around the R base function prop.test()
but have the advantage of performing pairwise and row-wise z-test of two proportions, the post-hoc tests following a significant chi-square test of homogeneity for 2xc and rx2 contingency tables.fisher_test()
, pairwise_fisher_test()
and row_wise_fisher_test()
: Fisher’s exact test for count data. Wrappers around the R base function fisher.test()
but have the advantage of performing pairwise and row-wise fisher tests, the post-hoc tests following a significant chi-square test of homogeneity for 2xc and rx2 contingency tables.chisq_test()
, pairwise_chisq_gof_test()
, pairwise_chisq_test_against_p()
: Chi-square test for count data.binom_test()
, pairwise_binom_test()

: performs exact binomial and multinomial tests. Alternative to the chi-square test of goodness-of-fit-test when the sample.counts_to_cases()
: converts a contingency table or a data frame of counts into a data frame of individual observations.mcnemar_test()
and cochran_qtest()
for comparing two ore more related proportions.prop_trend_test()
: Performs chi-squared test for trend in proportion. This test is also known as Cochran-Armitage trend test.get_test_label()
and get_pwc_label()

, reorder_levels()
and make_valid_levels()
model
added in the function emmeans_test()
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.friedman_effsize()
, computes the effect size of Friedman test using the Kendall’s W value.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.games_howell_test()

for computing effect size for Kruskal-Wallis test.p_round(), p_format(), p_mark_significant()
.wilcox_effsize()
