deptime.depth

The depth for which accumulation rate estimates should be calculated.

depth

Calculate in years per cm, or alternatively in cm per yr.

yrcm

Probability level at which to calculate the ranges.

prob

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. <code>yrsteps=1</code>.

Performs 'classical' age-depth modelling of dated sediment deposits - prior to applying more sophisticated techniques such as Bayesian age-depth modelling. Any radiocarbon dated depths are calibrated. Age-depth models are constructed by sampling repeatedly from the dated levels, each time drawing age-depth curves. Model types include linear interpolation, linear or polynomial regression, and a range of splines. See Blaauw (2010). <doi:10.1016/j.quageo.2010.01.002>.
