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.
install.packages("gbutils")You can install the development version of
gbutils from Github:
library(devtools)
install_github("GeoBosh/gbutils")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.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
