Learn R Programming

⚠️There's a newer version (3.1.5) of this package.Take me there.

The Forestplot package

A forest plot that allows for multiple confidence intervals per row, custom fonts for each text element, custom confidence intervals, text mixed with expressions, and more. The aim is to extend the use of forest plots beyond meta-analyses. This is a more general version of the original 'rmeta' package's forestplot function and relies heavily on the 'grid' package.

Questions

Due to the package's popularity I suggest that you start with asking questions on StackOverflow so that others can learn from your own problems. Add the tag r and forestplot so that others can quickly find the question.

Contributing

All contributions are welcome. The package is managed at GitHub and I suggest that you start with creating an issue. If you feel that you're able to solve the coding on your own then fork the package and once you're done, create a pull request.
