This task view covers packages which include facilities for meta-analysis of summary statistics from primary studies. The task view does not consider the meta-analysis of individual participant data (IPD) which can be handled by any of the standard linear modelling functions but it does include some packages which offer special facilities for IPD.
The standard meta-analysis model is a form of weighted least squares and so any of the wide range of R packages providing weighted least squares would in principle be able to fit the model. The advantage of using a specialised package is that (a) it takes care of the small tweaks necessary (b) it provides a range of ancillary functions for displaying and investigating the model. Where the model is referred to below, it is this model which is meant.
Where summary statistics are not available, a meta-analysis of significance levels is possible. This is not completely unconnected with the problem of adjustment for multiple comparisons but the packages below which offer this, chiefly in the context of genetic data, also offer additional functionality.
- The primary studies often use a range of statistics to present their results. Convenience functions to convert these onto a common metric are presented by: compute.es which converts from various statistics to d, g, r, z, and the log odds ratio, MAd which converts to mean differences, and metafor which converts to an extensive set of effect size measures for comparative studies (such as binary data, person years, mean differences and ratios, and so on), for studies of association (a wide range of correlation types), and for non-comparative studies (proportions, incidence rates, and mean change). It also provides for a measure used in psychometrics (Cronbach’s alpha). esc provides a range of effect size calculations with partial overlap with metafor but with some extras, noticeably for converting test statistics, and also includes a convenience function for collating its output for input to another package like metafor or producing a CSV file. estimraw estimates the cell frequencies from odds ratios, risk ratios, or risk differences. effsize contains functions to compute mean difference effect sizes (Cohen’s d and Hedges’ g) and measures of dominance (Cliff’s delta) and stochastic superiority (Vargha-Delaney A). effectsize provides a large number of different effect sizes and converts between them. psychmeta provides extensive facilities for converting effect sizes and correcting for various restrictions and measurement artifacts. metansue provides some methods for converting to effect sizes, while es.dif computes Cohen’s d, Hedges’ g, biased/unbiased c (an effect size between a mean and a constant), and e (an effect size between means without assuming variance equality) from raw data. MOTE provides a variety of conversions based on Cohen’s d. estmeansd converts between quantiles and means and standard deviations. metaBLUE estimates means and standard deviations from various order statistics. SingleCaseES provides basic effect sizes for single-case designs including parametric and non-overlap measures. smd computes standardised mean differences. CohensdpLibrary provides Cohen’s d from a variety of designs. metaHelper calculates values commonly used in meta-analysis with a focus on standardized mean differences and related statistics. metaConvert estimates 11 effect size measures.

- metagear provides many tools for the systematic review process including screening articles, downloading the articles, generating a PRISMA diagram, and some tools for effect sizes. revtools provides tools for downloading from bibliographic databases and uses machine learning methods to process them. citationchaser assists in the process of chasing citations. MetaNLP pre–processes titles and abstracts for use in screening before a meta-analysis.
- esci also provides a large range of effect sizes.
- metavcov computes the variance-covariance matrix for multivariate meta-analysis when correlations between outcomes can be provided but not between treatment effects.
- clubSandwich and metafor provide functions to impute variance-covariance matrix for multivariate meta-analysis.
- metafuse uses a fused lasso to merge covariate estimates across a number of independent datasets.

Fitting the model
- Four packages provide the inverse variance weighted, Mantel-Haenszel, and Peto methods: meta, metafor, rmeta, and epiR.
- For binary and time-to-event data, metafor also provides binomial-normal and the Poisson-normal models.
- Packages which work with specific effect sizes may be more congenial to workers in some areas of science. MAd provides functions for the meta-analysis of standardized mean differences and provides a range of graphics.
- psychmeta implements the Hunter-Schmidt method (also known as psychometric meta-analysis) including corrections for reliability and other artifacts.
- Bayesian approaches are contained in various packages. bspmma provides two different models: a non-parametric and a semi-parametric. Graphical display of the results is provided. bayesmeta includes shrinkage estimates, meta-regression, posterior predictive p-values, and forest plots via either metafor or forestplot. Diagnostic graphical output is available. metaBMA provides a Bayesian approach using model averaging; a variety of priors are provided and it is possible for the user to define new ones. MetaStan includes binomial-normal hierarchical models and can use weakly informative priors for the heterogeneity and treatment effect parameters. baggr provides facilities using Stan for hierarchical Bayesian models; graphical facilities are provided. brms can also fit Bayesian meta-analytic models using Stan as the backend. BayesCombo provides facilities using a Bayesian approach and has graphical facilities.

RoBMA provides a framework for estimating ensembles of meta-analytic models and using Bayesian model averaging to combine them it also provides meta-regression. ra4bayesmeta provides principled reference analysis within the Bayesian normal-normal model. metabup provides a Bayesian approach using basic uncertainty pooling.
- Some packages concentrate on providing a specialised version of the core meta-analysis function without providing a full range of ancillary functions. These are: metaLik which uses a more sophisticated approach to the likelihood, metatest which provides another improved method of obtaining confidence intervals, and CoTiMA which performs meta-analyses of correlation matrices of repeatedly measured variables for studies with different time lags using a SEM framework with OpenMx as the engine.

This is an active area of research and a variety of methods are available including what is referred to here as Reitsma’s method and the hierarchical summary receiver operating characteristic (HSROC) method. In many situations these are equivalent.
