This is a solution for continuous integration for R projects on Windows, using AppVeyor -- a CI testing service similar to Travis-CI. Under the hood, r-travis is used to perform the testing; this works even on Windows thanks to MinGW and MSYS.
- Sign up to AppVeyor.
- Enable testing for your project.
devtools::use_appveyor()in your project.
- (Optional) Adapt
appveyor.ymlto your needs according to the documentation.
- (Optional) Add a badge as described by the output of
- Be sure to supply a
.gitattributesfile that takes care of fixing CRLF conversion settings that are relevant on Windows. The one in this repo can be used for starters.
- Push to your repo to start building.
Build and test commands
environment: VARIABLE: value
R_VERSION: The version of R to be used for testing. Specify
oldrel, or a version number.
R_ARCH: The architecture to be used for testing, one of
RTOOLS_VERSION: The version of Rtools to be used for testing, defaults to the most recent Rtools. Specify e.g.
33for Rtools 3.3.
USE_RTOOLS: trueif Rtools needs to be installed, e.g. if you use install_github or if there are packages in Remotes: in your DESCRIPTION file. Defaults to
GCC_PATH: The path to GCC in the Rtools installation, currently one of
WARNINGS_ARE_ERRORS: Set to 1 to treat all warnings as errors, otherwise leave empty.
CRAN: The CRAN mirror to use, defaults to RStudio's CDN via HTTPS. Change to HTTP for R 3.1.3 or earlier.
R_BUILD_ARGS: Arguments passed to
R CMD build, defaults to
R_CHECK_ARGS: Arguments passed to
R CMD check, defaults to
PKGTYPE: Passed as
NOT_CRAN: Set this to
Currently, all vignettes (and the
VignetteBuilder entry in
DESCRIPTION) are removed prior to building (due to the absence of pandoc and LaTeX which are likely to be needed).
In contrast to Travis-CI, AppVeyor offers facilities for hosting artifacts. This can be configured by adding a section to the
appveyor.yml. The sample file is configured to deploy logs, and source and binary versions of the built package. Check the "ARTIFACTS" section for your project at AppVeyor.
Using a 64-bit R installation
Some R packages, notably
rJava, require a 64-bit installation of
Windows and R. If you try to install these packages on a 32-bit
system you'll see a message similar to:
Error: .onLoad failed in loadNamespace() for 'rJava', details: call: inDL(x, as.logical(local), as.logical(now), ...) error: unable to load shared object 'C:/Users/appveyor/AppData/Local/Temp/1/RtmpWa3KNC/RLIBS_bdc2913935/rJava/libs/i386/rJava.dll': LoadLibrary failure: %1 is not a valid Win32 application.
To solve this problem, add to your
platform: x64 environment: R_ARCH: x64
This will cause Appveyor to run your build on a 64-bit version of Windows Server, using the 64-bit R binary.
This wouldn't have been as easy without r-travis and the experience gained there. Thanks!
The win-builder project has been around much longer and provides more comprehensive testing; you still might want to use this service before submitting to CRAN.
