as.character.rawBlock

Convert Block of Binary Data into Strings

Description

This function takes a "rawBlock" object and generates human-readable strings for displaying the block. Each string contains a binary offset, the binary data in a raw machine format, and an interpretation of the data in a human-readable format.

Usage

## S3 method for class 'rawBlock'
as.character(x, width = NULL, machine = NULL,
             sep1 = "  :  ", sep2 = "  |  ",
             showOffset = TRUE, showHuman = TRUE, ...)

Arguments

`x`	A `"rawBlock"` object.
`width`	The number of bytes to display per string.
`machine`	The machine format to display; either `"hex"` or `"binary"`.
`sep1`	A separator to insert between the block offset and the machine format.
`sep2`	A separator to insert between the machine format and the human-readable format.
`showOffset`	If `FALSE`, the column of offsets is not included in the strings.
`showHuman`	If `FALSE`, the column of human-readable format is not included in the strings.
`...`	Other arguments to `as.character`.

Details

If either width or machine is NULL, the relevant value is taken from the "rawBlock" object. The human-readable format is taken from the "rawBlock" object.

Value

A character vector.
