Function to calculate the means using Linear models (lm or aov)
means_lm( data, trait, model, comparison, test = "SNK", anova = FALSE, plot_diag = FALSE, plot_treat = NULL, plot_groups = NULL, tab_vars = NULL, sep = NULL, digits = 3 )
data | Experimental design data frame with the factors and traits. |
---|---|
trait | Name of the trait. |
model | The effects in the model. See examples. |
comparison | Factor for the comparisons. |
test | Test comparison (default = "SNK"). Others: "TUKEY" & "DUNCAN". |
anova | ANOVA table (default = FALSE). |
plot_diag | Show diagnostic plots (default = FALSE). |
plot_treat | Treat of comparison in dot plot (default = NULL). See example. |
plot_groups | Group of comparison in dot plot (default = NULL). See example. |
tab_vars | Specific the variables in the summary table (default = NULL). |
sep | Separator between the variables when use |
digits | Number of digits in the table (default = 3). |
A list with two objects:
1. Summary statistics.
2. Means with the mean comparisons test.
Using tab_vars
select the variables shown the adjusted mean table with
the sep
. Mean comparison at p < 0.05.
