Estimating Lengths and Uncertainty from Photogrammetric Imagery R package Xcertainty version 1.0.1 Implementation of Bayesian models for estimating object lengths and morphological relationships between object lengths using photographic data collected from drones. The Bayesian model is described in "Bayesian approach for predicting photogrammetric uncertainty in morphometric measurements derived from drones" (Bierlich et al., 2021, <doi:10.3354/meps13814>). Software Depends: R (>= 3.0.2), nimble Imports: tidyr, dplyr, coda Suggests: testthat, knitr, rmarkdown, stringr, ggdist, tidyverse K.C.
