This isn't much of an improvement and does not even address the main concern but as no one has answered note that we can pass the filename as a character string and it will get "rb" automatically and we can just use "raw" if we like. Also n can be any size larger than the file size (see ?readBin) so if the file size is 10000 or less: readBin("toto.png", "raw", n = 10000, endian = "little") ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
