Sets the root directory for a set of iso_files (property
file_root in the file information), which is particularly useful for re-reading files (reread_iso_files) after they have changed location. Can optionally remove the previous root (
remove_embedded_root) if it is still embedded in the isofiles'
file_path instead of
file_root. Will warn about any paths that cannot be simplified by removing the embedded root.
iso_set_file_root( iso_files, root = ".", remove_embedded_root = NULL, quiet = default(quiet) )
collection of iso_file objects
new root directory for the isofiles. Can be relative to the current working directory (e.g.
set this parameter to a root path that is embedded in the isofiles'
whether to display (quiet=FALSE) or silence (quiet = TRUE) information messages. Set parameter to overwrite global defaults for this function or set global defaults with calls to iso_turn_info_message_on and iso_turn_info_message_off
