spmodel v0.12.0

spmodel 0.12.0

Major Updates

• Added eacf() to compute the empirical autocovariance function.

Minor Updates

• Changed the default size argument to the local argument in predict(..., block = TRUE) and augment(..., block = TRUE) from 1000 to 4000. This enhances the block prediction (i.e., Kriging) approximation's accuracy but can slightly increase computational complexity.
• Enhanced efficiency of block prediction (i.e., Kriging) for large newdata objects.
• Added a warning message that clarifies xcoord and ycoord are ignored when data is an sf object.
• Minor documentation updates.

Bug Fixes

• Fixed a bug in predict(object, newdata) and augment(object, newdata) that could cause NA values when the spatial covariance was "matern" and a location in newdata was the exact same as a location in data (the data argument used to fit object).
