+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.
