paleobioDB-package.R

#' We have developed paleobioDB, an R-package designed to make easy
#' and flexible queries of the Paleobiology Database, as well as to
#' visualize and download selected data. This package will make it
#' easy to access paleontological data in a way that should allow
#' those data to be further analyzed, including via packages and
#' libraries available in R.
#'
#' We programmed two different groups of functions. First, we
#' developed a set of general and flexible functions to wrap the
#' [PaleobioDB API](https://paleobiodb.org/data1.2/). These
#' functions connect R with each of the endpoints of the PaleobioDB
#' API. Second, based on these base functions, we programmed a second
#' set of functions intended to explore and visualize the fossil
#' occurrences in their geographic, temporal and taxonomic dimensions.
