df_htest(htest, test_statistics = TRUE, show_ci = TRUE, extract_names = TRUE)
describe_htest(htest, alpha = NULL, digits = 3)A S3 object of the class htest
A logical variable to display the test statistics.
A logical variable to display the confidence interval.
A logical variable to take the names from the S3 object (i.e., statistic for t.test would be "t")

#> [1] "The Welch Two Sample t-test is not statistically significant (t(17.776) = -1.86, p = 0.079, mean in group 1 = 0.75, mean in group 2 = 2.33, 95% C.I.[-3.37, 0.205]) at a 0.05 alpha-level. The null hypothesis cannot be rejected. At the desired error rate, it cannot be stated that the true difference in means between group 1 and group 2 is not equal to 0."
