skyscapeR is a open source R package for data reduction, visualization and analysis in skyscape archaeology, archaeoastronomy and cultural astronomy. It is intended to become a fully-fledged, transparent and peer-reviewed package offering a robust set of quantitative methods while retaining simplicity of use.
For information on how to use skyscapeR download the official vignette. This is slightly out of date though, so watch this space.
Just do:
if(!requireNamespace("devtools", quietly = TRUE)) { install.packages("devtools") }
devtools::install_github('f-silva-archaeo/skyscapeR')Major plotly implementation done (minor glitches to fix). Added a number of celestial mechanics functions that rely on swephR, including body.position(), moonphase(), riseset(), riseset.year() and solar.date() as well as support functions time2jd(), jd2time(), timestring() and long.date(). Added new function that creates a sketch of the sky for a given moment in time (may be useful for publications) called sky.sketch(). There may be glitches and lack of functoinality in some of these functions. Also, not passing CRAN checks and tests yet but watch this space.
This version opens the implementation of plotly for most plotting functions, bringing the much requested interactive functionalities. The implementation involves considerable tinkering, which has had side-effects in other functions. The package is therefore not ready for another release yet. Though it runs through the vignette without a hitch, some new functions, however, are not finalised yet and best to be avoided (e.g. anything in the plotting_plotly.R file for now).
This version has abandoned astrolibR ephemeris completely and, in its stead, has begun using the Swiss Ephemeris version of the JPL DE431 dataset. This is implemented via package swephR which is still in development and not on CRAN. You can find the offical swephR GitHub here. (Update: As of v0.3.0, when you install skyscapeR from GitHub it will automatically install swephR.)
The latest release version (v0.2.2) is available on CRAN. This Git contains the latest development version which has several bug fixes and additional tools (some of which might not have been fully tested).
