推荐答案

您可以直接从GitHub的库安装：

You can install directly from a GitHub repository:

if (!require('devtools')) install.packages('devtools')
devtools::install_github('apache/spark@v1.4.0', subdir='R/pkg')

您应该选择标记（ V1.4.0 以上）与您使用Spark版本。您可以使用在项目页面或直接与R标记的GitHub API ：

You should choose tag (v1.4.0 above) corresponding to the version of Spark you use. You can find a full list of tags on the project page or directly from R using GitHub API:

jsonlite::fromJSON("https://api.github.com/repos/apache/spark/tags")$name

如果您已经从一个下载页面ř库是在研究/ lib目录/ SparkR 子目录。它可用于直接安装SparkR。例如：

If you've downloaded binary package from a downloads page R library is in a R/lib/SparkR subdirectory. It can be used to install SparkR directly. For example:

$ export SPARK_HOME=/path/to/spark/directory
$ cd $SPARK_HOME/R/lib/SparkR/
$ R -e "devtools::install('.')"

您也可以加上R的lib到 .libPaths （从的这里）：

You can also add R lib to .libPaths (taken from here):

Sys.setenv(SPARK_HOME='/path/to/spark/directory')
.libPaths(c(file.path(Sys.getenv('SPARK_HOME'), 'R', 'lib'), .libPaths()))

无需任何额外的步骤

最后，你可以使用 sparkR 外壳：

Finally, you can use sparkR shell without any additional steps:

$ /path/to/spark/directory/bin/sparkR
