crossRings: dplR crossdating

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

Description

This function implements routines in dplR to crossdate TRWs.

Usage

crossRings(mdr, smp = 1, ncol = 1:length(mdr), fun = "corr", 
    ...)

Arguments

mdr	list. Set of detected TRWs such as that produced by multiDetect.
smp	numeric or character. Position or name in the set of the sample being crossdated.
ncol	numeric or character. Positions or names in the set of the TRWs used to crossdate the sample.
fun	character. Function in dplR to be implemented. Three functions can be used: corr.rwl.seg ('corr'), ccf.series.rwl ('ccf'), and spag.plot ('spag').
...	arguments to be passed to the dplR function.

Value

output of selected function.

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:
mrings <- multiDetect(img,
                      last.yr = 2013,
                      auto.det = TRUE,
                      plot = FALSE)

## corr analysis
crossRings(mrings,
           fun = 'corr',
           seg.length = 10,
           bin.floor = 0,
           lag.max = 2,
           make.plot = FALSE)
