Is there any function to convert binary string into binary or decimal value?
If I have a binary string 000101
, what should I do to convert it into 5
?
You could use the packBits
function (in the base
package). Bear in mind that this function requires very specific input.
(yy <- intToBits(5))
# [1] 01 00 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
# [26] 00 00 00 00 00 00 00
# Note that there are 32 bits and the order is reversed from your example
class(yy)
[1] "raw"
packBits(yy, "integer")
# [1] 5
There is also the strtoi
function (also in the base
package):
strtoi("00000001001100110000010110110111", base = 2)
# [1] 20121015
strtoi("000101", base = 2)
# [1] 5
