0. Analysis of phenological digital imagery- The package phenopix provides functions to process digital images of a vegetation cover, depict greennes index trajectories and extract relevant phenological stages.
3. Interface to use SIMPLACE from R- Package simplace is an interface to the crop modelling framwork SIMPLACE (www.simplace.net). It provides high level functions to run simulations and transform the output into R objects.
8. general multiple-table data management- Our objective is to develop classes of objects that (1) make handling multiple-table data sets easier and (2) seamlessly integrate with existing R plotting and model-fitting functions; our philosophy is to keep data management and data analysis separate.
