Hello David, The function haralickMatrix is not exported anymore but the function is still present in EBImage. The gray level co-occurrence matrix (GLCM) can be computed with EBImage:::.haralickMatrix. Example: library("EBImage") x <- matrix(runif(20*20), nrow=20) mask <- array(TRUE, dim=dim(x)) glcm <- EBImage:::.haralickMatrix(mask, x, nc=8) Feel free to help the maintainer to document and make this function publicly available again.
