Get Involved

openDendro is built by a small group and gets better when more people use it, break it and say so. You do not need to be a programmer to help.

Report a Bug or Ask for a Feature

This is the most useful thing you can do. Open an issue on the repository for the tool you were using:

• dplR
• dplPy
• xDateR
• iDetrend
• This website

A good report says what you did, what you expected and what happened. If you can attach a small file that shows the problem, we can usually fix it faster.

Test dplPy

dplPy is heading for its 1.0 release, and this is the time to find what is wrong with it. If you work with tree-ring data and know some Python, run your own collections through it and tell us what breaks, what is confusing and what is missing. If you already do the same analysis in dplR, a comparison of the two is especially welcome.

Write Code

We welcome contributions in R and Python. Fork the repository, make the change on a branch and open a pull request. For anything larger than a small fix, open an issue first so we can talk about the approach before you spend the time.

Read how we work before you start. In short: choices belong in arguments with documented defaults, functions fail loudly, and matching a legacy program's output is not a goal.
