How to get started with the
metapsyTools package is part of the Metapsy project.
Functions included in the package can be used to run meta-analyses of
Metapsy databases, or
of databases that adhere to the same data
standard, “out of the box” using R.
The package also contains a set of tools that can be used to prepare meta-analytic data sets based on the Metapsy data standard, and to calculate effect sizes (Hedges’ \(g\) and risk ratios, \(RR\)).
The package consists of two modules:
- A module to check the data format and calculate effect sizes for all possible study comparisons (preparation module);
- A module to select relevant comparisons for a specific meta-analysis, calculate the results (including subgroup, meta-regression, and publication bias analyses), and generate tables (analysis module).
The idea is to use the two modules in different contexts. For example, the preparation module can be used every time the database is updated to gather all information, calculate effect sizes, and bring the data into a format suitable for further analyses.
Prepared data sets that follow the Metapsy data standard build the basis for the analysis module. Researchers simply have to filter out the comparisons that are relevant for the investigation, and can then use functions of the package to run a full meta-analysis, including sensitivity and subgroup analyses.
The companion package of
metapsyData, meta-analytic databases can be
automatically downloaded into your R environment. Databases retrieved
metapsyData can directly be analyzed using
