expr_t_bayes: Making expression containing Bayesian t-test results

Description

Making expression containing Bayesian t-test results

Usage

expr_t_bayes(data, x, y, bf.prior = 0.707, paired = FALSE, k = 2, ...)

Arguments

data

A dataframe (or a tibble) from which variables specified are to be taken. A matrix or tables will not be accepted.

x

The grouping variable from the dataframe data.

y

The response (a.k.a. outcome or dependent) variable from the dataframe data.

bf.prior

A numeric value between 0.5 and 2 (default 0.707), the prior width to use in calculating Bayes Factors.

paired

Logical that decides whether the experimental design is repeated measures/within-subjects or between-subjects. The default is FALSE.

k

Number of digits after decimal point (should be an integer) (Default: k = 2).

...

Additional arguments (currently ignored).
