z<-packBits(rbinom(32,1,.5)==1,"integer")
Error in packBits(x, type) : argument 'x' must be raw, integer or logical
Taking a closer look at the C code

Question: how to convert raw to numeric
...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

about image and rgb
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
