Broadcasted Byte and Relational Operations on Raw Arrays
Description
The bc.raw() function performs broadcasted byte- and relational operations on arrays of type raw.
For bit-wise operations, use bc.bit.
For logical operations, use bc.b
Usage
bc.raw(x, y, op, ...)
## S4 method for signature 'ANY'
bc.raw(x, y, op)
Arguments
x, y
|
conformable raw vectors or arrays. |
op
|
a single string, giving the operator. Supported byte operators: pmin, pmax, diff. The "diff" operator performs the byte equivalent of abs(x - y). Supported relational operators: ==, !=, <, >, <=, >=. |
…
|
further arguments passed to or from methods. |
Value
For the byte operators:
A array of type raw, as a result of the broadcasted byte operation.
For relational operators:
A logical array as a result of the broadcasted relational comparison.
