General purpose TIFF file I/O for R users. This is currently the only such package with read and write support for TIFF files with floating point (real-numbered) pixels, and the only package that can correctly import TIFF files that were saved from ‘ImageJ’ and write TIFF files than can be correctly read by ‘ImageJ’ https://imagej.nih.gov/ij/. Also supports text image I/O.
