  digits = 3
)

Arguments

data

Experimental design data frame with the factors and traits.
trait

Name of the trait.
model

The effects in the model. See examples.
comparison

plot_diag

Show diagnostic plots (default = FALSE).
plot_treat

Treat of comparison in dot plot (default = NULL). See example.
plot_groups

digits

Number of digits in the table (default = 3).

Value

A list with two objects:

1. Summary statistics.

2. Means with the mean comparisons test.

Details

Using tab_vars select the variables shown the adjusted mean table with the sep. Mean comparison at p < 0.05.
