unroll: Unroll Genetic Horizons

Description

Generate a descretized vector of genetic horizons along a user-defined pattern.

Usage

unroll(top, bottom, prop, max_depth, bottom_padding_value = NA)

Arguments

top

vector of upper horizon boundaries

bottom

vector of lower horizon boundaries

prop

vector of some property to be "unrolled" over a regular sequence

max_depth

maximum depth to consider

bottom_padding_value

Examples

data(sp1)

# subset a single soil profile:
sp1.1 <- subset(sp1, subset=id == 'P001')

# demonstrate how this function works
x <- with(sp1.1, unroll(top, bottom, prop, max_depth=50))
plot(x, 1:length(x), ylim=c(55,0), type='b', cex=0.5)
