Usage

get_RW(rings)

Arguments

rings

A data frame with the identified rings, a result of the dprings() call on an individual profile

## load a single file
dp <- dpload(system.file("extdata", "00010001.dpa", package = "densitr"))
## trim and detrend the measurement
dp.trimmed <- dptrim(dp)
dp.detrended <- dpdetrend(dp.trimmed, type = "gam")
## identify rings
rings <- dprings(dp.detrended)
