Plot aggregate soil color data

Source: R/aggregateColorPlot.R

Generate a plot from summaries generated by aqp::aggregateColor().

aggregateColorPlot(
  x,
  print.label = TRUE,
  label.font = 1,
  label.cex = 0.65,
  label.orientation = c("v", "h"),
  buffer.pct = 0.02,
  print.n.hz = FALSE,
  rect.border = "black",
  horizontal.borders = FALSE,
  horizontal.border.lwd = 2,
  x.axis = TRUE,
  y.axis = TRUE,
  ...
)

Arguments

x

a list, results from aqp::aggregateColor()

print.label

logical, print Munsell color labels inside of rectangles, only if they fit

label.font

font specification for color labels

label.cex

font size for color labels

label.orientation

label orientation, v for vertical or h for horizontal

buffer.pct

extra space between labels and color rectangles

print.n.hz

optionally print the number of horizons below Munsell color labels

rect.border

color for rectangle border

horizontal.borders

optionally add horizontal borders between bands of color

horizontal.border.lwd

line width for horizontal borders

x.axis

logical, add a scale and label to x-axis?

y.axis

logical, add group labels to y-axis?

...

additional arguments passed to plot

Value

nothing, function called for graphical output
