new SOmerge function that allows multiple objects to be combined into a single map object
new SObin function that will create a raster density layer from longitude-latitude points
SOgg now does a better job of matching colours and text sizes to those specified in the input objects, so ggplot2-based maps should now be more visually consistent with non-ggplot2-based maps
new data set fronts_park that provides an alternative set of front locations as derived by Park & Durand 2019. Use it with e.g. SOmap(fronts = "Park") (or SOmap(fronts = TRUE) or SOmap(fronts = "Orsi") for the Orsi et al. 1995 front locations)
simplified (smaller size, faster to plot) layer for CCAMLR planning domains
various bug fixes and adjustments to cope with updates to package dependencies
lots of bug fixes
changes to internal SOmap object structures
SOplot() to add RGB raster objects.parameter names to many functions have been changed, to make them case- and style-consistent
SOauto_map renamed to SOmap_auto for consistency
refactored ggplot code
improved SOmap_auto functionality
SOauto_map() function and class is now defunct, replaced by SOmap_auto().Arguments mask and trim_background now removed from SOmap_auto().
Argument buffer removed from SOmap_auto(), changed expand to numeric fraction (expand = 0 equivalent to old expand = FALSE).
Argument sample_type to SOmap_auto() moved to internal function automap_nothing().
New internal functions to become the engine behind SOmap_auto(), automap_maker() to create a background extent from disparate inputs, and automap_nothing() to create a background by random data.
New auto extent logic for SOmap_auto() to address #30.
New reproj::reproj methods for SOmap_auto and SOmap classes.
Added control to SOauto_map to draw sp lines as lines, points as points correctly.
Added a NEWS.md file to track changes to the package.
