%description
This is a set of functions to retrieve information about GIMMS NDVI3g
files currently available online; download (and re-arrange, in the case of
NDVI3g.v0) the half-monthly data sets; import downloaded files from ENVI
binary (NDVI3g.v0) or NetCDF format (NDVI3g.v1) directly into R based on
the widespread 'raster' package; conduct quality control; and generate
monthly composites (e.g., maximum values) from the half-monthly input
data. As a special gimmick, a method is included to conveniently apply the
Mann-Kendall trend test upon 'Raster*' images, optionally featuring
trend-free pre-whitening to account for lag-1 autocorrelation.
