metR 0.16.0

New features

• EOF()'s rotate argument now will take a function to apply to the EOF loadings. rotate = TRUE is still supported but deprecated and will default to using function(x) stats::varimax(x, normalize = FALSE).

• Contour functions gain a proj.latlon to decide if the projection needs to go to latlon coordinates or to projected coordinates.

Breaking changes

• The GetSMNData() function is defunct. The functionality was a hack and hard to maintain and it's also very specific and should be out of scope for a general package.
• The trans argument of scales has been renamed to transform following ggplot2's change.
• scale_mag() internals are now much simpler and inherits all the functionality from common continuous scales. (thanks @teunbrand for the suggestion, #186)
• The step computed variable in geom_streamline() now goes from 0 to the total number of steps instead of from negative half to positive half.
