calc_mf2: Calculating the metabolic footprint of nematodes (two-factor)

In easynem: Nematode Community Analysis

Calculating the metabolic footprint of nematodes (two-factor)

Description

Metabolic footprints quantify the amplitude of Carbon utilisation by different food web components. The point in the middle of a rhombus represents the intersection of EI and SI and length of vertical and horizontal axes of the rhombus corresponds to the footprints of enrichment and structure components respectively.

Usage

calc_mf2(data, .group1, .group2)

Arguments

data	A nemindex-class object.
.group1	The group variable factor 1.
.group2	The group variable factor 2.

Details

To facilitate code interpretation, it is recommended to use the pipe symbol |> to connect functions:

nem_fun <- nem |> calc_nemindex() |> calc_mf2(con_crop, season)

Value

A mf2-class object that stores the desired visualization results.
