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. Plot density and distribution functions with automatic selection of suitable regions. 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.
The latest stable version is on CRAN.

Package gbutils
is a collection of (mostly small) functions used interactively
or in packages.
sim_numbers()
, sim_complex()
, sim_real()
- Simulate real or complex
numbers from (possibly partial) polar form specifications.
cdf2quantile()
- Compute quantiles from a given distribution function.
pseudoInverse()
- Compute pseudo-inverse matrices.
rpoly()
- create polynomials with real coefficients from zeroes (roots) given in
Cartesian or polar form.
plotpdf()
- Plot functions with automatic determination of the "interesting"
region (typically probability density and distribution functions)adjacencyOfClasses()
- Create inheritance graphs of S4 classes defined in
one or more packages.isNA()
- Is an object NA?
isargunnamed()
- Is an element of a list named?
missing_arg()
- Is an element of a pairlist missing?
parse_text()
- Parse expressions.
nposargs()
- Count the number of positional arguments used in a call.
shiftleft()
shiftright()
- Rotate vectors.
mintersect()
- Set intersection of arbitrary number of arguments.
myouter()
- Outer product using a non-vectorised function.
raw_history()
Get the command history in a character vector.
