Fast R and C++ Access to NIfTI Images R package RNifti version 1.9.0 CRAN Task View: MedicalImaging (https://CRAN.R-project.org/view=MedicalImaging) Provides very fast read and write access to images stored in the NIfTI-1, NIfTI-2 and ANALYZE-7.5 formats, with seamless synchronisation of in-memory image objects between compiled C and interpreted R code. Also provides a simple image viewer, and a C/C++ API that can be used by other packages. Not to be confused with 'RNiftyReg', which performs image registration and applies spatial transformations.
