  cex.max = 0.5,
  pch = 1,
  col = "black"
)

Arguments

`x`	a `SoilProfileCollection` object
`colname`	character vector of length 1, naming the column containing volume fraction data (horizon-level attribute)
`res`	integer, resolution of the grid used to symbolize volume fraction
`cex.min`	minimum symbol size
`cex.max`	maximum symbol size
`pch`	integer, plotting character code
`col`	symbol color, either a single color or as many colors as there are horizons in `x`
