About

Maintained by Daniel VartanianCRAN page ↗GitHub ↗Website ↗Issues ↗Declared funder: University of Sao Paulo (USP)

A complete toolkit to process the Munich ChronoType Questionnaire (MCTQ) for its three versions (standard, micro, and shift). MCTQ is a quantitative and validated tool to assess chronotypes using peoples' sleep behavior, originally presented by Till Roenneberg, Anna Wirz-Justice, and Martha Merrow (2003, doi:10.1177/0748730402239679).

Changes in 0.3.2

As of this version, a decoupling process related to some mctq utility functions will begin. Please pay attention to the deprecation warnings listed below.
Patch changes were made to random_mctq() to avoid warning messages due to lubridate package updates.
The utility functions assign_date(), cycle_time(), round_time(), shorter_interval(), longer_interval(), shorter_duration(), longer_duration(), sum_time(), and vct_sum_time() are now deprecated. These functions will be removed on the next mctq version. You can still find them in the lubritime package.
The utility function qplot_walk() is now deprecated. This function will be removed on the next mctq version. You can still find it in the gutils package.

Show all changes in 0.3.2Hide the rest of the changes in 0.3.2

qplot_walk() now uses ggplot2::geom_bar() or ggplot2::geom_histogram() to generate plots. It used ggplot2::qplot() before, now deprecated.
The ggplot2 package was added as an import. It's needed while qplot_walk() remains on the package and will be removed from imports in the next mctq version.
Mario Pedrazzoli and Ana Amelia Benedito-Silva were removed as authors. They were Scientific Advisers that helped with the initial mctq development, but are not part of the mctq project anymore.
The Interdisciplinary Sleep Research Group (GIPSO) was removed as funder. GIPSO is a research group that Mario and Daniel Vartanian have built together. Daniel (the main author and copyright holder of mctq) is no longer part of this group. The "funder" status was always symbolic.

From NEWS.md in the release

Install

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

install.packages("mctq", 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("ropensci/mctq")

Development version from ropensci/mctq. 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-mctq

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-mctq

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-mctq

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.
