Overview

About

Maintained by Andrey ChetverikovCRAN page ↗GitHub ↗Website ↗Issues ↗

Light-weight functions for computing descriptive statistics in different circular spaces (e.g., 2pi, 180, or 360 degrees), to handle angle-dependent biases, pad circular data, and more. Specifically aimed for psychologists and neuroscientists analyzing circular data. Basic methods are based on Jammalamadaka and SenGupta (2001) doi:10.1142/4031, removal of cardinal biases is based on the approach introduced in van Bergen, Ma, Pratte, & Jehee (2015) doi:10.1038/nn.4150 and Chetverikov and Jehee (2023) doi:10.1038/s41467-023-43251-w.

Changes in 1.4.0

density_asymmetry(): the kernel density estimate is now wrapped around the circle (wrap = TRUE), so mass near +/- circ_space/2 is no longer truncated. This is a no-op to ~1e-13 for orientation or colour errors, but it matters for data with a 180-degrees-off reversal mode, such as motion direction.
density_asymmetry(): the +/- circ_space/2 point is now excluded from the positive and negative sums (exclude_antipode = TRUE), like zero. It is the same angle reached from two sides, and with an odd n it was counted twice.
density_asymmetry(): a bandwidth narrower than the grid spacing now rescales yvar and the bandwidth together (rescale_narrow = TRUE) so the kernel spans at least one cell. Without it, the rectangle sum aliases: on a narrow error distribution with bw.SJ()-selected bandwidth the returned asymmetry was off by 7.5% of its value at the default n = 181, now 0.4%.

density_asymmetry(): the two signs are now paired on a rounded abs(x), since seq() is not bitwise symmetric for every n (on n = 1801, 604 of 900 pairs failed to match and dropped out of the sums entirely).
density_asymmetry_discrete(): the same four fixes, with the same argument names and defaults. Wrapping there is done by evaluating stats::density() over the neighbouring periods and folding the images back, since augmenting the sample with shifted copies would run into density()'s binning range.
The fixes above default to the corrected behaviour; pass wrap = FALSE, exclude_antipode = FALSE, rescale_narrow = FALSE for pre-1.4.0 results.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("circhelp", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("achetverikov/circhelp")

Development version from achetverikov/circhelp. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-circhelp

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-circhelp

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-circhelp

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
