...binary file in "integer" and "float" data. I can do this job in this way: (as below) first convert 4 byte raw to bits then pack bits back to "integer", but it not work for "float",I worry about the performance. raw4 = raw_buffer[1:4] bits = rawToBits(raw4) packBits(bits, type = "integer") Best wishes Really hope to get your response [[alternative HTML version deleted]]

Hi all, I have a 16 bit image (TIFF) and i want to analyse the pixels distribution. So, i obtain a matrix which values are between 0 and 2^16 -1. Now i would like to represnt this image with the fucntions rgb() and image(). I am not sure , but i think that only 256 colors are available. So is there a solution to represent all the palette of the colors or i have to limit the representations with
