rmedsem 1.1.1

  • New backend for PLS-SEM and PLSc-SEM models estimated with plssem

rmedsem 1.1.0

CRAN release: 2026-09-16

Breaking changes

  • summary() returns a summary.rmedsem object
  • as.data.frame() returns a plain data frame
  • rmedsem() stops with an error for models that previously ran but gave wrong or empty results
  • ci.two.tailed now determines all intervals
  • blavaan: the direct effect’s pval is now the posterior probability of the opposite sign
  • mcreps defaults to 5000 and is no longer raised to the sample size
  • RID is not reported if the direct effect is not significant; RIT() warns if the total effect is too small

New features

  • summary() method
  • New methods coef(), confint() and nobs() for rmedsem objects.
  • rmedsem.blavaan() gains ci.two.tailed and hdi (highest-density intervals)
  • Printing is now an extensible S3 method system
  • Result objects gain the elements zlc.method
  • All exported functions check their arguments and stop with informative messages
  • lavaan: a warning is given if the model did not converge.
  • cSEM: new seed argument; results are reproducible with set.seed()

Bug fixes

  • lavaan and modsem models with labelled regression paths (e.g., read ~ a*math) now work
  • blavaan: the rows of the printed table were shifted relative to their labels
  • modsem: the moderation effects are printed in causal direction
  • cSEM: the bootstrap interval of the indirect effect was taken from the incorrect row
  • digits and indent are passed correctly to the effect-size output.
  • plot_coef() no longer emits a position_dodge() warning
  • Very small p-values are no longer printed as 0
  • plot_effect() title and caption are wrapped to fit small figures
  • summary() and plot_effect() flag RIT and RID values that should not be interpreted
  • Clearer printed output
  • Dependencies on dplyr and purrr removed

Documentation

  • Help pages were merged into a compact set: ?rmedsem, ?rmedsem-methods, ?effect-sizes and ?plot.rmedsem
  • Examples for all backends
  • Corrected and completed the documentation of the datasets (incl. sources and response scales)
  • New article “Working with the results”
  • Added CRAN badge to README

rmedsem 1.0.0

CRAN release: 2026-03-16

  • Initial CRAN release.
  • Support for mediation analysis with lavaan (CB-SEM), cSEM (PLS-SEM), blavaan (Bayesian SEM), and modsem (moderated mediation).
  • Implements Baron and Kenny (1986) and Zhao, Lynch & Chen (2010) approaches.
  • Reports indirect effects via Sobel, Delta, and Monte-Carlo methods.
  • Effect size measures: RIT and RID.
  • Summary and plot methods for results.
  • Fix standard error calculation for standardized coefficients in rmedsem.lavaan and rmedsem.modsem (contributed by Kjell Slupphaug).
  • New ci.two.tailed parameter for configurable confidence interval width.
