exponentially ramped sedimentation rate model to convert time to stratigraphy

Description

Apply a exponentially increasing increasing sedimentation rate model to convert time to stratigraphy.

Usage

expSedRamp(data, sr_start, sr_end)

Arguments

data	Input data set should consist of a matrix with 2 columns with the first being time and the second being the proxy
sr_start	Initial sedimentation rate (in cm/kyr).
sr_end	Final sedimentation rate (in cm/kyr).

Value

Returns a list which contains 10 elements element 1: time series in the depth (m) domain element 2: sedimentation rate curve

Author(s)

Based on the sedRamp function of the 'astrochron' R package.
