stretch: Stretch some depths of a core

In rbacon: Age-Depth Modelling using Bayesian Statistics

Stretch some depths of a core

Description

Stretch squeezed depths e.g., calculate the original depths of depths that were squeezed. Accompanies the squeeze function.

Usage

stretch(d, boundary, times)

Arguments

d	The depth(s) to be stretched
boundary	The depth below which depths should be stretched
times	The factor by which the depths should be stretched

Value

The stretched depth(s)

Examples

  stretch(25.75,25,20)
## Not run: 
  # To play the accordion, first squeeze an existing core.
  # Let's squeeze the depths below 10 cm core depth 20 times:
  Bacon("accordion", 1)
  dets <- info$dets
  dets[,4] <- squeeze(dets[,4], 10, 20)

  # make a new directory for the squeezed core, and place the dets file there:
  dir.create("Bacon_runs/squeezed")
  write.table(dets, "Bacon_runs/squeezed/squeezed.csv", row.names=FALSE, sep=",")

  # now run that squeezed core, adding a boundary (10cm) and adapting the acc.mean prior (20x):
  Bacon("squeezed", 1, boundary=10, acc.mean=c(5, 20*5))
  # finally, plot while stretching the depths onto the original scale:
  agedepth(accordion=c(10,20))

## End(Not run)
