print.rawBlock: Print Method for Block of Binary Data

In hexView: Viewing Binary Files

Description

This function displays a "rawBlock" object. Each line of output contains a binary offset, the binary data in a raw machine format, and an interpretation of the data in a human-readable format. The object contains parameters controlling the format of the display, some of which may be overridden in the call to print.

Usage

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

Arguments

x	A "rawBlock" object.
width	The number of bytes to display per line of output.
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 printed.
showHuman	If FALSE, the column of human-readable format is not printed.
page	If TRUE the output is sent to the file viewer specified by getOption("pager").
...	Other arguments to print.

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.
