estimateSoilDepth: Estimate Soil Depth

Description

Estimate the soil depth of a single profile within a SoilProfileCollection object.

Usage

estimateSoilDepth(f, name = "hzname", top = "hzdept", bottom = "hzdepb", p = 'Cr|R|Cd', 
no.contact.depth = NULL, no.contact.assigned = NULL)

Arguments

f

A SoilProfileCollection object of length 1, e.g. a single profile

name

the name of the column that contains horizon designations

top

the name of the column that contains horizon top depths

bottom

the name of the column that contains horizon bottom depths

p

a REGEX pattern for determining contact with bedrock

no.contact.depth

in the absense of contact with bedrock, a depth at which we can assume a standard depth

no.contact.assigned

assumed standard depth

Value

• a single integer, the soil depth

Examples

data(sp1)
depths(sp1) <- id ~ top + bottom

# apply to each profile in a collection, and save as site-level attribute
sp1$depth <- profileApply(sp1, estimateSoilDepth, name='name', top='top', bottom='bottom')

# sample data
data(gopheridge, package='soilDB')

# run on a single profile
estimateSoilDepth(gopheridge[1, ])

# apply to an entire collection
profileApply(gopheridge, estimateSoilDepth)
