diagnosticPropertyPlot2: Diagnostic Property Plot (lattice)

In ncss-tech/sharpshootR: A Soil Survey Toolkit

Diagnostic Property Plot (lattice)

Description

Generate a graphical description of the presence/absence of soil diagnostic properties.

Usage

diagnosticPropertyPlot2(f, v, k, grid.label = "upedonid", sort.vars = TRUE)

Arguments

f	SoilProfileCollection object
v	character vector of site-level attribute names of logical type
k	an integer, number of groups to highlight
grid.label	the name of a site-level attribute (usually unique) annotating the y-axis of the grid
sort.vars	sort variables according to natural clustering (TRUE), or use supplied ordering in v

Details

This function attempts to display several pieces of information within a single figure. First, soil profiles are sorted according to the presence/absence of diagnostic features named in v. Second, these diagnostic features are sorted according to their distribution among soil profiles. Third, a binary grid is established with row-ordering of profiles based on step 1 and column-ordering based on step 2. Blue cells represent the presence of a diagnostic feature. Soils with similar diagnostic features should 'clump' together. See examples below.

Value

a list is silently returned by this function, containing:

rd

a data.frame containing IDs and grouping code

profile.order

a vector containing the order of soil profiles (row-order in figure), according to diagnostic property values

var.order

a vector containing the order of variables (column-order in figure), according to their distribution among profiles
