Arguments

.data

data.frame or tibble from which to source variables.

values

A vector of data values

groups

A vector with exactly two unique values for a two-sample t-test, or NULL for a one-sample t-test

alternative

a character string specifying the alternative hypothesis, must be one of "two.sided" (default), "greater" or "less". You can specify just the initial letter.

mu

a number indicating the true value of the mean (or difference in means if you are performing a two sample test).

var_equal

a logical variable indicating whether to treat the two variances as being equal. If TRUE then the pooled variance is used to estimate the variance otherwise the Welch (or Satterthwaite) approximation to the degrees of freedom is used.

conf_level

confidence level of the interval.

values_x, values_y

Paired vectors of data values for the paired t-test.
