+# SparkR CRAN Release
+
+To release SparkR as a package to CRAN, we would use the `devtools` package. Please work with the
+`[email protected]` community and R package maintainer on this.
+
+### Release
+
+First, check that the `Version:` field in the `pkg/DESCRIPTION` file is updated. Also, check for stale files not under source control.
+
+Note that while `check-cran.sh` is running `R CMD check`, it is doing so with `--no-manual --no-vignettes`, which skips a few vignettes or PDF checks - therefore it will be preferred to run `R CMD check` on the source package built manually before uploading a release.
+
+To upload a release, we would need to update the `cran-comments.md`. This should generally contain the results from running the `check-cran.sh` script along with comments on status of all `WARNING` (should not be any) or `NOTE`. As a part of `check-cran.sh` and the release process, the vignettes is build - make sure `SPARK_HOME` is set and Spark jars are accessible.
+
+Once everything is in place, run in R under the `SPARK_HOME/R` directory:
+
+```R
+paths <- .libPaths(); .libPaths(c("lib", paths)); Sys.setenv(SPARK_HOME=tools::file_path_as_absolute("..")); devtools::release(); .libPaths(paths)
+```
+
+For more information please refer to http://r-pkgs.had.co.nz/release.html#release-check
+
+### Testing: build package manually
+
+To build package manually such as to inspect the resulting `.tar.gz` file content, we would also use the `devtools` package.
+
+Source package is what get released to CRAN. CRAN would then build platform-specific binary packages from the source package.
+
+#### Build source package
+
+To build source package locally without releasing to CRAN, run in R under the `SPARK_HOME/R` directory:
+
+```R
+paths <- .libPaths(); .libPaths(c("lib", paths)); Sys.setenv(SPARK_HOME=tools::file_path_as_absolute("..")); devtools::build("pkg"); .libPaths(paths)
+```
+
+(http://r-pkgs.had.co.nz/vignettes.html#vignette-workflow-2)
+
+Similarly, the source package is also created by `check-cran.sh` with `R CMD build pkg`.
+
+For example, this should be the content of the source package:
+
+```sh
+DESCRIPTION	R		inst		tests
+NAMESPACE	build		man		vignettes
+
+inst/doc/
+sparkr-vignettes.html
+sparkr-vignettes.Rmd
+sparkr-vignettes.Rman
+
+build/
+vignette.rds
+
+man/
+ *.Rd files...
+
+vignettes/
+sparkr-vignettes.Rmd
+```
+
+#### Test source package
+
+To install, run this:
+
+```sh
+R CMD INSTALL SparkR_2.1.0.tar.gz
+```
+
+With "2.1.0" replaced with the version of SparkR.
+
+This command installs SparkR to the default libPaths. Once that is done, you should be able to start R and run:
+
+```R
+library(SparkR)
+vignette("sparkr-vignettes", package="SparkR")
+```
+
+#### Build binary package
+
+To build binary package locally, run in R under the `SPARK_HOME/R` directory:
+
+```R
+paths <- .libPaths(); .libPaths(c("lib", paths)); Sys.setenv(SPARK_HOME=tools::file_path_as_absolute("..")); devtools::build("pkg", binary = TRUE); .libPaths(paths)
+```
+
+For example, this should be the content of the binary package:
+
+```sh
+DESCRIPTION	Meta		R		html		tests
+INDEX		NAMESPACE	help		profile		worker
+```

 Libraries of sparkR need to be created in `$SPARK_HOME/R/lib`. This can be done by running the script `$SPARK_HOME/R/install-dev.sh`.
 By default the above script uses the system wide installation of R. However, this can be changed to any user installed location of R by setting the environment variable `R_HOME` the full path of the base directory where R is installed, before running install-dev.sh script.

+The [instructions](http://spark.apache.org/contributing.html) for making contributions to Spark also apply to SparkR.
 If you only make R file changes (i.e. no Scala changes) then you can just re-install the R package using `R/install-dev.sh` and test your changes.
 Once you have made your changes, please include unit tests for them and run existing unit tests using the `R/run-tests.sh` script as described below.

 #### Generating documentation
 
 The SparkR documentation (Rd files and HTML files) are not a part of the source repository. To generate them you can run the script `R/create-docs.sh`. This script uses `devtools` and `knitr` to generate the docs and these packages need to be installed on the machine before using the script. Also, you may need to install these [prerequisites](https://github.com/apache/spark/tree/master/docs#prerequisites). See also, `R/DOCUMENTATION.md`
