Plot density and distribution functions with automatic selection of
suitable regions. Numerically invert (compute quantiles) distribution
functions. Simulate real and complex numbers from distributions of their
magnitude and arguments. Optionally, the magnitudes and/or arguments may
be fixed in almost arbitrary ways. Create polynomials from roots given in
Cartesian or polar form. Small programming utilities: check if an object
is identical to NA, count positional arguments in a call, set
intersection of more than two sets, check if an argument is unnamed,
compute the graph of S4 classes in packages.
