Description

Hello! We recently updated several RStudio cheat sheets, and unfortunately now the translations are no longer up to date. The translations listed below are only one or two versions behind, and so only need small updates instead of translating an entire document from scratch. These would make good first projects and should be relatively quick to update.

You can find editable keynote and powerpoint files for the new cheat sheets in the keynotes/ and powerpoints/ folders. Current translations can be found in the translations/ folder. Once you have finished your updated translation, save the file as the same name as the current translation, and submit a pull request per the contributing guidelines.

In your pull request description please include "Addresses #204" to link to this issue.
