In clam: Classical Age-Depth Modelling of Cores from Deposits

Calculates *for each iteration* the slope of a straight curve between depths just above and below the desired point.

Description

Calculates *for each iteration* the slope of a straight curve between depths above and below the desired point. Requires sufficiently dense density of depths, e.g. yrsteps=1.

Usage

deptime.depth(depth, yrcm = TRUE, prob = 0.95)

Arguments

depth	The depth for which accumulation rate estimates should be calculated.
yrcm	Calculate in years per cm, or alternatively in cm per yr.
prob	Probability level at which to calculate the ranges.

Details

To calculate sedimentation times at a depth. Before running this, run your core in clam and store the data, so, make sure to set storedat=TRUE. Renamed from previous accrate.depth function to avoid confusion with accrate.depth function of rbacon.

Value

Returns (invisibly) the modelled deposition times for a specific depths, a histogram and confidence ranges.

Examples

  base_temp_dir <- tempdir()
  clam_dir <- file.path(base_temp_dir, "clam_runs")
  dir.create(clam_dir, recursive = TRUE, showWarnings = FALSE)
  clam(coredir=clam_dir, storedat=TRUE)
  dp <- deptime.depth(20)
  summary(dp)
  deptime.depth(20, FALSE) # to calculate accumulation rates in cm/yr
