R: read binary file of unsigned chars
I am trying to read a binary file of unsigned chars into R. The binary file is supposed to be storing integers 0 to 7 in unsigned char format but I am unable to get it. I have tried the following:
readBin(con = "tmp.out", what = "character", size = 1, n = 604*800)
But I get essentially gibberish.
I am aware that there are questions that are of a similar nature on StackOverflow but none of them seem to address exactly my question (or did not seem to). Any help would be greatly appreciated! Thank you for your time.

I read esoteric formats into R quite a bit. Perhaps provide some sample data?

Happy to, but can you give me a clue as to how to provide the data (it is in the form of a binary file). Alternatively, is it possible to create an unsigned character binary file in R?

I have found the answer that is:
xx <- readBin(con = "tmp.out", what = "integer", n = 604 * 800, size = 1, signed = F)
Basically, there is a signed option in the readBin function and a size option that should be set to 1 (byte).
