Distilles the most relevant data from an output object of t.test and displays the results in a compact format.
t_out(toutput, n.equal = TRUE,
welch.df.exact = TRUE, welch.n = NA,
d.corr = FALSE, print = TRUE)t_out(toutput,...) returns a list containing (1) a description of the t-test (two-sample t-test, Welch-test, paired-samples t-test, one-sample t-test) and (2) a line with formatted results.
Output object created by a call to t.test.
Only applicable to two-sample t-tests. If sample sizes are not equal, n.equal specifies a vector of sample sizes, e.g., n.equal = c(12,8).
Only applicable to Welch-tests. Indicates whether Welch-adjusted or unadjusted degrees of freedom (dfs) are reported (default=TRUE, i.e., Welch-adjusted dfs). If set to FALSE, the parameter welch.n has to be set as well.
Only applicable to Welch-tests with unadjusted degrees of freedom. Parameter should be equal to the total sample size n=n_1+n_2.
Only applicable to one-sample or paired-samples t-tests. If TRUE, Cohen's ds are computed using sqrt(2)-correction. Default changed to FALSE from version 1.5 onwards with an additional feedback message showing the use of corrections.
Force results to be displayed, even if the function output is assigned to a variable (e.g., output <- t_out(...); logical; default=TRUE).
