Contains new age models created with the IntCal20 (Reimer et al., 2020),
SHCal20 (Hogg et al., 2020) and Marine20 (Heaton et al., 2020) calibration
curves, in combination with the package ageR (Villegas-Diaz et al., 2022).
Represents the age_model table in the database.
age_modelA data frame (tibble object) with
95954 rows and 8 variables:
Unsigned integer: Unique identifier for the type of
model (e.g. IntCal20 = 8) (as in the model_name table)
Unsigned integer: Unique identifier for each
sample (as in the sample table)
Integer: Mean age of the sample
Integer: Median age of the sample
Integer: Lower bound of the 95% confidence interval
for the median age
Integer: Lower bound of the 75% confidence interval
for the median age
Integer: Upper bound of the 75% confidence interval
for the median age
Integer: Upper bound of the 95% confidence interval
for the median age
