GNU R package for Utilities for Simulation, Plots, And More

 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.
