profile_plot.default: Profile Plot

Description

Generate a simple diagram of a soil profile, with annotated horizon names.

Usage

## S3 method for class 'SoilProfileList':
profile_plot(d, color = "soil_color", width = 0.2, 
cex.names = 0.5, plot.order = 1:d$num_profiles, add = FALSE,
scaling.factor = 1, y.offset = 0, max.depth = d$max_depth, \dots)

Arguments

d

a SoilProfileList object

color

the name of the column containing R-compatible color descriptions

width

scaling of profile widths

cex.names

character scaling applied to horizon names

plot.order

a vector describing the order in which individual SoilProfile objects from the parent should be plotted

add

add to an existing figure

scaling.factor

vertical scaling of the profile heights

y.offset

vertical offset for top of profiles

max.depth

lower depth boundary of plot

...

other arguments passed into lower level plotting functions

Value

• A new plot of soil profiles is generated, or optionally added to an existing plot.

Details

This function sets the margins before plotting, so previous calls to par(mar=...) will be overridden.

Examples

library(aqp)
data(sp1)

# add color vector
sp1$soil_color <- with(sp1, munsell2rgb(hue, value, chroma))

# convert to SoilPofileList class object
sp1.list <- initProfileList(sp1)

# plot profiles
profile_plot(sp1.list)
