metR 0.13.0

New features

• The new function Smooth2D() smooths a 2D field (hence the name). There are two smoothing methods. smooth_svd() computes the SVD of the field and reconstructs it keeping only the leading values that ensures a maximum variance lost. smooth_dct() computes the Discrete Cosine Transform of the field and sets a proportion of the components to zero.

Bug Fixes

• Fixed a bug in geom_streamline() when plotting multiple fields on the same panel.

• Fixes a bug with GetTopography() on Windows.

• Updates documentation to use valid HTML5 per CRAN's new format.

• Fixes the "The following aesthetics were dropped during statistical transformation" warning for contours.

• Removes ReadNetCDF() file and URL checking because it didn't work in some cases.
  (#164, thanks @pascaloettli)

Breaking changes

• Due to the udunits2 package being orphaned, ReadNetCDF() not longer uses it to parse dates and times. The homebrewed parser might be more limited, and the wild variety of netCDF files in the wild makes it hard to fully test. Please report any issues you have!
