sgsR 1.3.2

enhancement - sample_systematic() - changed how tessellation was used internally and visualized during plotting.

fixed - strat_map() - #20 greatly simplified algorithm using suggestion from R. Hijmans (added as author to algorithm). Issue was related to level matching with categorical variables.

fixed - sample_ahels() - swapped plot marker icons to be consistent with other functions.

sgsR 1.3.1

fixed - sample_systematic() - added random translation to sampling grid to ensure unbiased sampling.

sgsR 1.3.0

new - sample_existing() - has been added. This algorithm sub-samples and existing sample using internal latin hypercube sampling. Constraints in the form of the cost parameter akin to sample_clhs() exist. Sub-sampling can be performed on existing samples alone, or using population level mraster distributions.

new - mask_existing() - internal function for masking exising samples using access buffers.

sgsR 1.2.1

fixed - sample_systematic() - bug where cellsize values that caused no samples to intersect with the raster would cause extract_metrics() to provide an error about existing not having any samples. Added a check for intersection and corresponding error message.

enhancement - Added quiet to extract_metrics() & extract_strata() to allow internal use without messages.
