transformeR: An R package for climate data post-processing

Bedia, J., Iturbide, M., and Gutiérrez, J.M.

transformeR is an R package for climate data manipulation and transformation including subsetting, regridding, and data conversion. This package builds on two main data structures (grid and station) to deal with gridded and point data (including metadata) from observations, reanalysis, seasonal forecasts and climate projections. Thus, it considers ensemble members as a basic dimension of the data structures. This package is part of the climate4R bundle, formed by loadeR, transformeR, downscaleR and visualizeR.
