Examples

x <- sample(0:9999, 10000)
y <- binstr(x) # length is 14 bits

## Not run: 
# alternate (but slower) conversion to binary string
R.utils::intToBin(x)

## End(Not run)

# convert binary string to integer value (very fast)
strtoi(y, base = 2)
strtoi(substr(y, 1, 4), base = 2)
strtoi(substr(y, 5, 8), base = 2)
strtoi(substr(y, 9, 11), base = 2)
strtoi(substr(y, 12, 14), base = 2)

# see also `binary()` and `unbinary()` in the `composition` package (requires x11)
