##---- Should be DIRECTLY executable !! ---- ##-- ==> Define data, use random, ##-- or do help(data=index) for the standard data sets. ## The function is currently defined as function (pimgs, subset = 1:length(pimgs)) { bad <- unlist(lapply(pimgs, function(x) is.null(x$image)))[subset] subset <- subset[!bad] res <- as.image.pimg(pimgs[[subset[1]]]) if (length(subset) == 1) return(res) for (i in subset[-1]) { img <- pimgs[[i]] Xpos <- img$offset[1] Ypos <- img$offset[2] Xind <- Xpos:(Xpos + dim(img$image)[1] - 1) Yind <- Ypos:(Ypos + dim(img$image)[2] - 1) res$z[Xind, Yind] <- res$z[Xind, Yind] + img$image } res }
