nem_plot-ter2-method: Visualizing the results of the ternary analysis (two-factor)

In easynem: Nematode Community Analysis

Visualizing the results of the ternary analysis (two-factor)

Description

The nem_plot function is generalized to the ter2-class and is used to visualize the results of the ternary analysis. This function visualizes the distribution of nematode communities using the relative abundance of nematodes of cp1, cp2, and cp3-5 or the relative biomass of herbivorous nematodes, bacterivorous nematodes, and fungivorous nematodes as the three axes of a ternary plot.

Usage

## S4 method for signature 'ter2'
nem_plot(object, type, point_size = 1, legend_cex = 0.9, ...)

Arguments

object	A ter2-class object.
type	Visualize the nematodes by their feeding habits or by their cp values.
point_size	Size of the points. Default is 1.
legend_cex	Size of the legend text. Default is 0.9
...	Additional parameters passed to Ternary::TernaryPlot().

Details

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

nem_plot <- nem |> calc_ter2(con_crop, season) |> nem_plot()

Value

A recordedplot object from Ternary::TernaryPlot.

Examples

nem <- read_nem(tab = easynem_example("nemtab1.csv"),
                tax = easynem_example("nemtax1.csv"),

            nem_plot(type = cp)
