sed_rate_from_matrix | R Documentation |
Construct a sedimentation rate generator (function factory) from a matrix, e.g. one returned from get_data_from_eTimeOpt
. This generator can be passed on to sedrate_to_multiadm
to estimate age-depth models from it.
If mode is "deterministic", the generator evaluates the sedimentation rates at heights specified by height
, if the mode is "poisson" it is evaluated at heights that are determined based on a poisson point process. At these heights, the value of the sedimentation rate is determined based on the (pseudo) pdf that is determined by the matrix values.

height |
vector of heights |
sedrate |
vector of sed. rates x values |
matrix |
matrix of sed rate y values. Must have as many columns as length(height) and as many rows as length(sedrate). |
mode |
character, "deterministic" or "poisson". Determines at which stratigraphic heights the sed rate is determined. If "deterministic" this will be the heights in |
rate |
numeric, rate of the Poisson point process determining frequency of sedimentation rate changes. |
expand_domain |
should sedimentation rates be defined below/above the highest/lowest height in the section? If TRUE, the sed rate values are the values at the closest interpolated point, if FALSE it will be NA |
transform |
a function, the identity function by default. How should the values of the (pseudo)pdf defined by the entries of |
a function factory for usage with sedrate_to_multiadm
sedrate_to_multiadm()
for estimating sedimentation rates based on the outputs, get_data_from_eTimeOpt()
for extracting data from the eTimeOpt
function of the astrochron package.
