Hi,
How can I convert from 8-bit RGB color to [0-1] interval (sRGB) and
vice-versa?
Thanks in advance

If you have the R/G/B values separately, divide by 255, and use function rgb
in grDevices. If you have the hex values, paste these into a string, and use
something like
col2rgb(#2C312C)

8-bit color graphics often refers to a situation where each pixel is 8
bits, and the colour comes from a 256-colour palette lookup table.
If you really have a 8 bit palettized colour lookup, as Barry assumes, you
better use one of the build-in conversions, for
