I have released to CRAN version 1.0 of the “glcm” R package for calculating image texture measures from grey-level co-occurrence matrices (GLCMs). Type:

install.packages("glcm")

at your R command prompt to download the latest CRAN release. This version contains several new features, most importantly the ability to calculate rotation invariant textures, and to automatically handle images that cannot fit in memory (using features from the excellent raster package).
