If an iso file is read with the debug mode on, the source data (e.g. binary file) is stored with the file. By default this is not the case because it makes file objects unnecessarily large. Use these functions to retrieve and explore source structures.
iso_get_source_file_structure(iso_file)
iso_print_source_file_structure(x, ..., save_to_file = NULL)
# S3 method for iso_file
iso_print_source_file_structure(x, ..., save_to_file = NULL)
# S3 method for binary_isodat_file
iso_print_source_file_structure(
x,
start = 1,
length = NULL,
end = start + length,
...,
save_to_file = NULL
)
# S3 method for binary_isodat_file
print(x, start = x$pos, length = 200, ...)iso file object
the object for which to print the source file structure.
additional parameters depending on source file types
whether to save the source file structure to a text file (provide file path, will overwrite anything already in the file!) in addition to printing it out
starting position in the binary file to print from (prints the first block that spans this range)
length in the binary file to print to (by default NULL, which means print everything)
until which point in the binary file to print to. If provided, overrides whatever is specified in length
Typically these functions are used for debugging purposes only.
