有没有什么函数可以将二进制字符串转换为二进制或十进制值？
如果我有一个二进制字符串000101，我应该怎么做才能将其转换为5?
你可以使用packBits函数（在base包裹）。请记住，此功能需要非常具体的输入。
(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
还有strtoi函数（也在base包裹）：
strtoi("00000001001100110000010110110111", base = 2)
# [1] 20121015
strtoi("000101", base = 2)
# [1] 5
