class RTictoc(RPackage):
    """Functions for timing R scripts, as well as implementations of Stack and
    List structures.

    This package provides the timing functions 'tic' and 'toc'
    that can be nested. One can record all timings while a
    complex script is running, and examine the values later. It
    is also possible to instrument the timing calls with custom
    callbacks. In addition, this package provides class
    'Stack', implemented as a vector, and class 'List',
    implemented as a list, both of which support operations
    'push', 'pop', 'first', 'last' and 'clear'."""
