Users are welcome to contribute new packages to Bioconductor. Packages
must meet a checklist of standards of functionality,
documentation, and interoperability. See
Contact information to obtain instructions for
submitting new packages.
Authors receive initial feedback in 1 to 3 weeks. Packages will be checked
for adherence to the Bioconductor package guidelines and the checklist below
by a member of Bioconductor team. Package developers should consult the full
Bioconductor Package Guidelines. Submission
implies commitment to package maintenance across multiple release cycles.
Packages must satisfy the following checklist:
R CMD build,
R CMD check, and
R CMD BiocCheck (see the BiocCheck package) on all supported platforms (Windows,
Macintosh, Linux) with no errors or warnings, using a recent R-devel.
The result of
R CMD build must be less than 4MB;
R CMD check must
complete within 5 minutes.
- Contain a DESCRIPTION file with valid contact information, an informative
title and description, correct license specification, appropriate biocViews
terms, valid version number.
- Set Version: 0.99.0 in the DESCRIPTION. Subsequent versions created
during the review process will be numbered 0.99.1, 0.99.2, etc.
When released, your package's version number will be automatically
incremented to 1.0.0.
- Contain a NAMESPACE that imports all symbols used in the package, and
exports just those symbols the package author identifies as appropriate.
Use of a NAMESPACE implies that appropriate packages are mentioned in the
Imports: field of the DESCRIPTION file.
- Contain a Sweave-style vignette that illustrates the major uses of the
package. The vignette must be evaluated during package installation; a
static vignette (e.g., PDF) is not acceptable.
- Contain complete help pages. This includes accurate description of function
parameter and return values, and meaningful examples.
- Make use of appropriate existing packages (e.g., biomaRt, AnnotationDbi,
Biostrings) and classes (e.g., ExpressionSet, AnnotatedDataFrame,
RangedData, Rle, DNAStringSet) to avoid duplication of functionality
available in other Bioconductor packages.
- Contain no extraneous files (e.g., '.DS_Store', '.project', '.svn', etc.),
files with invalid names (e.g., differing only in case), or code that
cannot be distributed under the license specified by the author.
- Packages must not already be available on CRAN.
- Packages should have a descriptive name that is not already in use.
See if it is by running
cannot have a package name that is case-insensitively equal to
an existing package name in CRAN or Bioconductor.
Packages should also conform to the following:
- Use existing S4 classes and generic functions; see the
Package Guidelines for details on
- Include an inst/NEWS file for providing users with information on package

From submission to acceptance
- Package developers submit their first version of a package with the
version number at 0.99.0
- A detailed package review is returned to the developer
- The package developer updates their package, increments the version
number to 0.99.1, builds and checks the package on the local
machine, and re-submitts the package to Bioconductor.
- The process is repeated, with version bumps on each iteration, until
the package is accepted to Bioconductor.
- A package was submitted as 'DemoPackage_0.99.0.tar.gz'
- During package review it was recommended that biocViews terms in the
DESCRIPTION file, a NEWS file and a vignette be added.
- The package developer made all the recommended changes, bumped the
version number to 0.99.1 in the DESCRIPTION file, built and checked
the package on their local machine.
- The developer uploaded the tar ball 'DemoPackage_0.99.1.tar.gz' to
Following acceptance of a package:
- Packages accepted on the tracker are added to the devel branch of
the Bioconductor SVN repository, with the current version number of
the accepted package.
- Packages are then built by the Bioconductor nightly build
process. If the build is successful, the package has its own
'landing page' created, and the package is made available to users
of the 'devel' branch of Bioconductor via
- Developers may continue to make changes to their package, but now do
so to the version in the subversion repository.
- Developers should bump the
z portion of their version number every
time they commit changes to their package, following the
Version numbering guidelines. If
developers don't bump the version, the changes made to their package
do not propagate to the Bioconductor web site and package
- The accepted package tarball is added to the devel branch by the
Bioconductor group members. The package is built on all supported
platforms during the nightly build. If the build is successful, the
package has its own 'landing page' created. Users of the devel
branch can now download the "0.99.1" version of "DemoPackage" using
The package developer wants to add a new function to his
package. The following steps are recommended.
- Check out the package from the svn repository (using the link,
username and password) emailed to the Developer.
- Add the functionality to the package.
- Increment the version number from 0.99.1 to 0.99.2.
- Build and check the package.
- Commit changes to the svn repository.
The following day, after the build report is generated - the users
can now access the "0.99.2" version from the Bioconductor
If the developer had made an error and not bumped the version from
0.99.1 to 0.99.2, then the package would be built by the nightly build
process, but the new version would not propogate to the public
biocLite("DemoPackage") would return the old version
0.99.1 of the package.

We are eager to enhance the quality and interoperability of Bioconductor
software and will provide additional support when requested by package
developers. Example areas of assistance include use of appropriate S4
structures, specific guidance on efficient implementation, guidance on code
structure, and critical assessment of package documentation and structure.
