This R package includes methods used to analyse trends in unstructured occurrence datasets and a range of useful functions for mapping such data in the UK. The package is currently under development.

Tutorials

We have developed tutorials for a few of the functions in the package:

  • frescalo - A function for using Frescalo (Hill, 2011), a tool for analysing occurrence data when recording effort is not known.
  • mixedModel - A function for using the mixed model analysis used by Roy et al (2011)
  • sparta - [No longer supported] A function that implements a range of methods used to analyses trends in unstructured occurrence datasets
  • plot_GIS - A function for plotting GIS data
  • create_weights - A function for creating a frescalo weights file

Installation

To install the development version of sparta, it's easiest to use the devtools package:

# install.packages("devtools")
# NOTE: If you have not installed devtools before you will need to restart you R
# session before installing to avoid problems

library(devtools)
install_github("sparta", username = 'BiologicalRecordsCentre')

library(sparta)

PLEASE NOTE THAT SINCE THIS PACKAGE IS IN DEVELOPMENT THE STRUCTURE AND FUNCTIONALITY OF THE PACKAGE ARE LIKELY TO CHANGE OVER TIME. WE WILL TRY TO KEEP THIS FRONT PAGE AND TUTORIALS UP TO DATE SO THAT IT WORKS WITH THE CURRENT MASTER VERSION ON GITHUB
