Dear Reza,

There is the metafor website at: https://www.metafor-project.org/

This is where you can find the "Analysis Examples", "Tips and Notes", and various other pieces of information. If you want to search the metafor website, just use the search box at the top of the page.

And there is the package documentation, which one can read in a nicely formated way here:


This is where you can find lots of examples as well, since at the end of each help page, there is an 'Examples' section where the use of a function or dataset is illustrated. dat.ishak2007 is (actually was -- see below) one of the datasets in metafor and hence you are thinking of the Examples section from the help file for this dataset.

Recently, we (Thomas White, Daniel Noble, Alistair Senior, W. Kyle Hamilton, and I) released a new R package called metadat:


It contains a large collection of meta-analysis datasets, useful for teaching purposes, illustrating/testing meta-analytic methods, and validating published analyses.

All of the datasets that were in metafor have now been moved over there. So now, you can look at the package documentation for metadat:


And there, you will find:


The metadat package actually provides a function called datsearch() which allows you to search the package based on the 'concept terms' that are defined for the various datasets or a full-text search:


I hope this clarifies things.
