Creating and submitting a package to the Comprehensive R Archive Network (CRAN) is a great way to share your code with the broader R community. However, the process can be challenging and time-consuming. Here is an overview of the steps involved and the requirements to meet:
Step 1: Develop the Package
The first step in creating a package is to write the code and documentation. The code should be written in R and should be well-documented, following the standards set by the roxygen2 package. The documentation should include the function and package descriptions, examples, and references.
Step 2: Prepare the Package for Submission
Once the package is developed, it needs to be prepared for submission to CRAN. This involves several steps, including:
Creating a tarball of the package
Checking the package for errors using the R CMD check command
Creating a README file that includes instructions for installing and using the package
Creating a NEWS file that includes a description of the changes made in each version of the package
Creating a LICENSE file that specifies the terms under which the package can be used
Step 3: Submit the Package to CRAN
After the package is prepared, it can be submitted to CRAN. The submission process involves several steps:
Create an account on the CRAN submission site
Upload the tarball of the package
Fill out the submission form, which includes information such as the package name, description, and author information
Wait for the CRAN team to review the package
Step 4: Address Feedback from the CRAN Team
After the package is submitted, the CRAN team will review it and provide feedback. The feedback may include requests to fix errors, improve the documentation, or make other changes to the package. The package developer will need to address the feedback and resubmit the package for review.
Step 5: Package is Accepted
Once the package meets all the requirements and the CRAN team approves it, it will be included in the CRAN repository, and users can install it using the install.packages command.
In conclusion, creating and submitting a package to CRAN is a rigorous process, but it can be a rewarding way to share your code with the broader R community. By following the standards and guidelines, you can create a high-quality package that is easy to use and maintain.
