In easynem: Nematode Community Analysis

Compute Tukey Honest Significant Differences (two-factor)

Description

The HSD2() is used to Compute Tukey Honest Significant Differences for grouped data and create compare2-class. This function is only applicable to two-factor analysis, see HSD for a single factor version of the function.

Usage

HSD2(data, .group1, .group2, y, ...)

Arguments

data	An easynem-class data.
.group1	Grouping variables factor 1.
.group2	Grouping variables factor 2.
y	Dependent variable (numeric data).
...	Other parameters for TukeyHSD.

Details

To facilitate code interpretation, It is recommended to use this function in conjunction with the calc_compare2 function:

nem_compare <- nem |> calc_compare2(.group1 = con_crop, .group2 = season, y = pH, method = HSD2)

Value

An compare2-class object.

Examples

nem <- read_nem(tab = easynem_example("nemtab1.csv"),
                tax = easynem_example("nemtax1.csv"),
                meta = easynem_example("nemmeta1.csv"))
nem_test <- nem |>
              calc_compare2(.group1 = con_crop, .group2 = season, y = pH, method = HSD2)
