In measuRing: Detection and Control of Tree-Ring Widths on Scanned Image Sections

ring-width object reduction

Description

ring-width objects are reduced to dplR chronologies.

Usage

reduceList(mls, name.ls = "ringWidths", 
    empty.rm = TRUE)

Arguments

mls	List. Object from multiDetect
name.ls	Character. name of the list to be reduced.
empty.rm	Logical. Remove empty lists.

Value

Examples

## Paths to three image sections in the package:
img <- system.file(c("P105_a.tif",
                     "P105_b.tif",
                     "P105_d.tif"),
                   package="measuRing")

## Recursive detection (arbitrary ring borders and formation years
## are included):
mrings <- multiDetect(img,
                      inclu = list(c(1:40),c(1:30),c(1:41)),
                      last.yr = list(2014, 2013, 2012),
                      auto.det = c(FALSE,TRUE,FALSE),
                      plot = FALSE)
## Reducing the processed ring withs 
wide <- reduceList(mrings)
tail(wide)
