A set of minimal extensions to R’s built-in bitwise operations, mainly for use with bitmasks.

This provides C functions to AND, OR or XOR a vector of integers together, to compress down to a single int. It also provides infix operators for bitwise operations, using the base functions.

If using `bitops`

, the infix operators are redundant.

You can install the development version of vectorbitops like so:

This is a basic example of use for some simple bitmasking.

```
library(vectorbitops)
vals <- c(
"foo" = 1 %<<% 0,
"bar" = 1 %<<% 1,
"baz" = 1 %<<% 2
)
mask_a <- vals["foo"]
mask_b <- vals["baz"]
mask_c <- bit_vector_OR(vals[c("bar", "baz")])
flags <- bit_vector_OR(vals[c("foo", "bar")])
# In practise, one would just use `bitwAnd` for the below, but for demostration purposes:
bit_vector_AND(c(flags, mask_a)) # 1
bit_vector_AND(c(flags, mask_b)) # 0
bit_vector_AND(c(flags, mask_c)) # 2
```
