Full Changelog: v2.2.0...v2.2.2.0

SWMPrExtension Release version 2.2.0

Fix empty season failure in seasonal_dot.R.
Changed all Seasonal Kendal test results to plot with custom png icons instead of ggplot characters.
Fixed multiple seasonal means being plotted in seasonal_barplot.R
Change projection for national_sk_map to a UTM projection to reduce distortion in png icons.

SWMPrExtension v2.1.0

• Removed tmap, tmaptools, and OpenStreetMap due to issues with required package {rJava}.
• Adding ggmap for background raster map as a suggested package., but with optional vector map if ggmap not installed
• Adding ability to pass a map to the local map functions
• CRAN release

SWMPrExtension 2.0.0

Removes {sp} dependencies
Removes {mapshot} and PhantomJS dependencies
Uses OpenStreetMap tiles for background tiles on reserve-level plots.
Fixes (fingers crossed) proj4 issues.

Updates for 2021 processing of 2020 SWMP reports

Added He'eia stations and ability to update reserve stations
Wind speed units can be changed
Suppressed many routine warnings ("joining by dummy", etc.)
replaced gather() with pivot_longer()

Updates to stay current with {dplyr} and {sp}

Changes to dplyr::summarise, CRS, and examples in several programs.
Bug fix in threshold_identification.R when using multi-variable nutrient calls

Version 1.1.5 Fixes issue #49

Fixes issue #49 by changing row-wise tidier workflow. We were using a deprecated approach, which will be defunct with upcoming {broom} release (0.7.0).

R 4.0 update

Revision to accommodate changes with R 4.0, PROJ >= 4, and related changes. No significant changes to look or function of outputs.

Fix national map CRS

Corrected the crs information for the national mapping programs, national_sk_map.R and res_national_map.R to have the correct WGS84 Lambert Azimuthal Equal Area projection information. Reprojected and renames us_aea.rda -> us_laea.rda to reflect this change. This change should eliminate any need for spatial reprojection and avoid some of the upcoming PROJ 6 issues with proj4 strings.
