Overview

About

Maintained by Isak RoalkvamCRAN page ↗GitHub ↗Website ↗Issues ↗

Provides tools for shoreline dating coastal Stone Age sites. The implemented method was developed in Roalkvam (2023) doi:10.1016/j.quascirev.2022.107880 for the Norwegian Skagerrak coast. Although it can be extended to other areas, this also forms the core area for application of the package. Shoreline dating is based on the present-day elevation of a site, a reconstruction of past relative sea-level change, and empirically derived estimates of the likely elevation of the sites above the contemporaneous sea-level when they were in use. The geographical and temporal coverage of the method thus follows from the availability of local geological reconstructions of shoreline displacement and the degree to which the settlements to be dated have been located on or close to the shoreline when they were in use. Methods for numerical treatment and visualisation of the dates are provided, along with basic tools for visualising and evaluating the location of sites.

Changes in 1.1.1

Added the parameter date_probability_scale to shoredate_plot() to make it possible to adjust the scaling of the probability distribution of the shoreline date to better fit the plot.
Removed dependency on rgeos (@rsbivand, #9)

shoredate 1.1.0

Added a vignette that demonstrates how the package can be applied to other regions outside south-eastern Norway (@benmarwick, #6).
Removed the function check_target_location() and set up more specific and appropriate checks within interpolate_curve() and target_plot().
Added the package rnaturalearth to suggests in DESCRIPTION. This can be used with target_plot() to create a map for any area of the world, extending the transferability of the package (@benmarwick, #6).

Show all changes in 1.1.1Hide the rest of the changes in 1.1.1

Made most graphical parameters in shoredate_plot(), displacement_plot() and target_plot() variables that be adjusted by the user (@kanishkan91, #5).
Adjusted how the geom column of sf objects passed to target_plot() are evaluated (@kanishkan91, #2).
Cleaned up code to reduce the amount of @Import and @ImportFrom in NAMESPACE, opting instead for the package::function() syntax (@kanishkan91, #4).
Set up a pkgdown site for the package, served through GitHub at https://isakro.github.io/shoredate/ (@kanishkan91, #3).

shoredate 1.0.2 (2023-05-02)

shoredate_hdr() and shoreline_date() now returns the weighted mean date.
shoreline_date() now has the parameter model, which accepts either "none"

or "gamma". If "none" is specified then the distance between site and shoreline

is assumed to be zero.

Now using the package ggspatial for scale bar in maps rather than ggsn,

due to the retiring of r-spatial packages (@rsbivand, #1).

shoredate 1.0.1 (2023-03-06)

sum_shoredates() can now handle NA dates.
shoreline_date() now accepts a vector of site names for the argument

sites if interpolated displacement curves are also provided.

shoredate 1.0.0 (2023-01-19)

First release.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("shoredate", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("isakro/shoredate")

Development version from isakro/shoredate. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-shoredate

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-shoredate

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-shoredate

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
