Overview

About

Maintained by Itziar FernandezCRAN page ↗GitHub ↗Issues ↗

Provides a collection of functions to fit and explore single, multi-component and restricted Frequency Modulated Moebius (FMM) models. 'FMM' is a nonlinear parametric regression model capable of fitting non-sinusoidal shapes in rhythmic patterns. Details about the mathematical formulation of 'FMM' models can be found in Rueda et al. (2019) doi:10.1038/s41598-019-54569-1.

Changes in 0.4.1

Enhancements:

Improved convergence behavior of the fitFMM_back() significantly reduces the number of iterations needed to reach a good solution.
Clarified the warning message issued when high amplitude values are detected.

Changes:

Fixed a bug in the construction of the logarithmic omega grid: exp(log(omegaMin)) did not match omegaMin exactly due to floating point precision. The grid is now constructed using L + 2 points, and the first and last are removed.
Internal code restructuring: calculateSingleCosPhi() was separated from calculateCosPhi(), and a new function calculateDesignMatrix() was added.
The show() method for FMM objects is now registered by default. The previous manual call to addShowMethod() is no longer needed.

New features:

Added a new internal function: mobius(), used in the updated optimization routine.
Added dependency on the gsignal package (used for the hilbert() function).

From NEWS.md in the release

Install

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

install.packages("FMM", 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("FMMGroupVa/FMM-base-R-package")

Development version from FMMGroupVa/FMM-base-R-package. 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-fmm

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-FMM

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-FMM

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.
