hexmode {base} | R Documentation |
Convert or print integers in hexadecimal format, with as many digits as are needed to display the largest, using leading zeroes as necessary.
as.hexmode(x) ## S3 method for class 'hexmode' as.character(x, ...) ## S3 method for class 'hexmode' format(x, width = NULL, upper.case = FALSE, ...) ## S3 method for class 'hexmode' print(x, ...)

Class "hexmode"
consists of integer vectors with that class
attribute, used merely to ensure that they are printed in hex.
If width = NULL
(the default), the output is padded with
leading zeroes to the smallest width needed for all the non-missing
elements.
as.hexmode
can convert integers (of type "integer"
or
"double"
) and character vectors whose elements contain only
0-9
, a-f
, A-F
(or are NA
) to class
"hexmode"
.
There is a !

these recycle their arguments to the length of the longer and then
apply the operators bitwise to each element.
