Convert a signed integer to a nybble in raw data.
This function converts a signed integer ranging from -8 up to 7 into
either the high or low nybble of a byte, represented by raw data.
signedIntToNybble(int_dat, which = c("low", "high"))int_dat |
A single |
which |
A character string indicating whether the nybble should
be set to the " |
Nybbles are 4 bit values, where each byte (8 bits) holds two nybbles.
A high nybble (left-hand side of a byte) and a low nybble (right-hand
side of a byte). This function converts a signed integer value
ranging from -8 up to 7 to a nybble and sets it as either a high or a low
nybble in raw data.
Returns raw data of the same length as int_dat.
The returned raw data holds either low or high nybbles (as specified
by which) based on the provided signed integers.

## generate some integers in the right range: dati <- sample(-8:7, 100, replace = TRUE) ## Set the low nybbles of rawl based on dati: rawl <- signedIntToNybble(dati) ## Set the high nybbles of rawl based on dati: rawh <- signedIntToNybble(dati, "high")
