Overview

About

Maintained by Elaine BorghiCRAN page ↗GitHub ↗Issues ↗

Provides WHO Child Growth Standards (z-scores) with confidence intervals and standard errors around the prevalence estimates, taking into account complex sample designs. More information on the methods is available online: https://www.who.int/tools/child-growth-standards.

Changes in 1.1.0

Method

The Weight-for-length/height (zwfl) z-score indicator is now also computed for observations where weight or lenhei is outside the plausible ranges. The plausible ranges were 0.9-58 for weight and 38-150 for lenhei.

Z-scores

The resulting data frame of anthro_zscores has a new column c9mo_flag to indicate whether an incorrect measurement position was observed with children younger than 9 months.

Performance

For inputs with cluster/strata = NULL a faster method was added for this special case to compute anthro_prevalence. This method yields the same results within an observed tolerance of < 0.0001 on test data.

Bugfix

Fixed a bug during prevalence computation when a value used as a group (like sex) contains NA and at the same time all values in that group are NA as well. Previously this resulted in a hard stop of the computation, now the code gracefully handles it.

From NEWS.md in the release

Install

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

install.packages("anthro", 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("WorldHealthOrganization/anthro")

Development version from WorldHealthOrganization/anthro. 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-anthro

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-anthro

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-anthro

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.
