Overview

About

Maintained by Davood TofighiCRAN page ↗GitHub ↗Website ↗Issues ↗

Computes confidence intervals for nonlinear functions of model parameters (e.g., product of k coefficients) in single-level and multilevel structural equation models. Methods include the distribution of the product, Monte Carlo simulation, and bootstrap methods. It also performs the Model-Based Constrained Optimization (MBCO) procedure for hypothesis testing of indirect effects. References: Tofighi, D., and MacKinnon, D. P. (2011).

Changes in 1.6.1

Naming convention cleanup

p_prod3() is renamed to pprodnormal3() to match the existing pprodnormal()/qprodnormal() family. p_prod3() remains available as a silent (non-warning) alias and will gain a formal deprecation warning in a future release.
ProductNormal2() remains available but is superseded by ProductNormal() for direct construction; internal callers now use ProductNormal() directly.
The ci() generic's dispatch argument is renamed from mu to object for consistency with the package's other S7 generics (cdf(), dist_quantile()). This only affects callers using ci(mu = ...) as a named argument; positional calls (ci(mu, ...)) are unaffected.

Show all changes in 1.6.1Hide the rest of the changes in 1.6.1

Undocumented internal helpers (validate_ProductNormal(), is_valid_for_computation(), ProductNormal_from_lavaan()) are now hidden from the package documentation index (@noRd); they remain available internally but are not part of the public API. | Old | New | |-----|-----| | p_prod3(q, mean, cov, ...) | pprodnormal3(q, mean, cov, ...) | | ci(mu = ..., Sigma = ..., quant = ...) | ci(..., Sigma = ..., quant = ...) (positional) |

Documentation and lint

Added @examples to all exported functions/generics that previously lacked them, addressing goodpractice::gp() advisories ahead of CRAN resubmission.

Install

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

install.packages("RMediation", 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("data-wise/rmediation")

Development version from data-wise/rmediation. 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-rmediation

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-RMediation

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-RMediation

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.
