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, name='name', 
cex.names=0.5, cex.depth.axis=cex.names, cex.id=cex.names+(0.2*cex.names), 
print.id=TRUE, id.style='top', plot.order=1:d$num_profiles, add=FALSE, scaling.factor=1, y.offset=0, 
max.depth=d$max_depth, n.depth.ticks=5, shrink=FALSE, shrink.cutoff=3,
abbr=FALSE, abbr.cutoff=5, ...)

Arguments

d

a SoilProfileList object

color

the name of the column containing R-compatible color descriptions

width

scaling of profile widths

name

the name of the column containing the horizon designation

cex.names

character scaling applied to horizon names

cex.depth.axis

character scaling applied to depth scale

cex.id

character scaling applied to profile id

print.id

should the profile id be printed above each profile? (TRUE)

id.style

profile ID printing style: 'top' = centered above each profile (default), 'side' = 'along the top-left edge of profiles'

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

suggested lower depth boundary of plot

n.depth.ticks

suggested number of ticks in depth scale

shrink

should long horizon names be shrunk by 80% ?

shrink.cutoff

character length defining long horizon names

abbr

should the profile ID be abbreviated?

abbr.cutoff

suggested minimum length for abbreviated IDs

...

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. Depth limits (max.depth) and number of depth ticks (n.depth.ticks) are *suggestions* to the pretty() function. You may have to tinker with both parameters to get what you want. The 'side' id.style is useful when plotting a large collection of profiles, and/or, when profile IDs are long.

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)

# plot profiles, using alternate profile ID label style
profile_plot(sp1.list, id.style='side')
