How to Calculate True Minimum Ages from Age Class Data in R
Introduction In this blog post, we’ll explore how to supplement age class determination with observation data in R. We’ll take a closer look at the provided dataset and discuss the process of combining age class data with year-of-observation information to calculate true minimum ages.
The dataset includes yearly observations structured like this:
data <- data.frame( ID = c(rep("A",6),rep("B",12),rep("C",9)), FeatherID = rep(c("a","b","c"), each = 3), Year = c(2020, 2020, 2020, 2021, 2021, 2021, 2017, 2017, 2017, 2019, 2019, 2019, 2020, 2020, 2020, 2021, 2021, 2021), Age_Field = c("0", "0", "0", "1", "1", "1", "0", "0", "0", "2", "2", "2", "3", "3", "3", "4", "4", "4") ) The goal is to convert the Age_Field column into 1, 2, 3 values and compute the age with simple arithmetic.
