functions now accommodate legacy (or historical) sites, a minimum distance between sites, and two approaches for selecting replacement sites (reverse hierarchical ordering and nearest neighbor). -
Syntax for the analysis functions (
*_analysis()
) has been significantly simplified. -
Risk difference analysis is now available using the
diffrisk_analysis()
function. -
Trend analysis is now available using the
trend_analysis()
function. -
The
sp_summary()
function is now available to summarize sampling frames, design sites, and analysis data. -
The
sp_plot()
function is now available to visualize sampling frames, design sites, and analysis data.
Minor Updates
- Several functions have undergone minor changes to syntax and scope.
Breaking Changes
- Several functions have changed (both inputs and outputs) and functions in version 5.0.0 are not always backwards compatible with functions from previous versions. Though we recommend users upgrade existing code to work with the current version's simpler implementations, backwards compatibility can be achieved by downloading previous versions of spsurvey.
