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 different years
## of formation of last rings in the images years are specified:
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)
str(mrings)

## Updating the call in mrings using new arguments: 
mrings1 <- update(mrings,
                  exclu = list(c(1:4),c(1:4),c(1:4)),
                  last.yr = 2016)
