Wrap previous proj4 code with reproj, proj4 is no longer imported by spex.
Add new features for basic list, data frame or matrix input.
New spex(clipboard = TRUE/FALSE) argument to take advantage of leafem copy extent (WIP).
New latitude functions latitudecircle to build a polar circle.
Now return all cells as polygons if raster has no values.
Improved handling of na.rm, also now TRUE by default. #13 Thanks to Adriano Fantini.
A modest speed-up (up to 2X) for polygonize by more careful use of R.
better column name for resulting Spatial data frame
new functions xlim and ylim, supporting anything understandable by spex
new extent method for sf objects, otherwise missing in the core packages
new spex support for sf objects
spex() with no input argument will return the extents of the current par ‘usr’ setting (if only graphics devices had metadata registration for the space in use …)
polygonize, qm_rasterToPolygons, and qm_rasterToPolygons_sp gain na.rm argument to optionally remove any cells that are NA (in the first layer)
