$ dcli -g nodes -l oracle ORE CMD INSTALL arules_1. For installing a package on multiple database servers, such as those in an Oracle Real Application Clusters (Oracle RAC) or a multinode Oracle Exadata Database Machine environment, use the ORE script in conjunction with the Exadata Distributed Command Line Interface (DCLI) utility.

If the package depends on any packages that are not in the R distribution in use, download the sources for those packages, also.įor a single Oracle Database instance, replace the R script with ORE to install the packages in the same location as the Oracle R Enterprise packages.īehind the scenes, the ORE script performs the equivalent of setting R_LIBS_USER to the value of $ORACLE_HOME/R/library, and all R packages installed with the ORE script are installed to this location. To install a package on the database server so that it can be used by any R user and for use in embedded R execution, an Oracle DBA would typically download the package source from CRAN using wget. Unlike the default R script, the ORE script installs packages to a location writable by user oracle and accessible by all ORE users - $ORACLE_HOME/R/library.
It can be used to start R, run batch scripts, and build or install R packages. The ORE script is a wrapper for the default R script, a shell wrapper for the R executable. On Linux and UNIX platforms, the Oracle R Enterprise Server installation provides the ORE script, which is executed from the operating system shell to install R packages and to start R. The Oracle R Enterprise installation is performed by user oracle, which typically does not have write permission to the default site-wide library, /usr/lib64/R/library. The database-side R engine just needs to know where to find the R packages. The steps for installing and configuring packages for use with Oracle R Enterprise are the same as for open source R.

Renviron in your home area if it does not already exist, and add the following piece of code to it:Įmbedded R execution with Oracle R Enterprise allows the use of CRAN or other third-party R packages in user-defined R functions executed on the Oracle Database server. To set the library location and avoid having to specify this at every package install, simply create the R startup environment file.

Refer to the install.packages help file in R or execute R CMD INSTALL -help at the shell command line for a full list of command line options. $ R CMD INSTALL arules_1. -library=/home/username/Rpackages R> install.packages("arules", lib="/home/username/Rpackages") For example, to create an R package repository in your home directory: You can accept the personal library path chosen by R, or specify the library location by passing parameters to the install.packages function. If you don't run R as root, you won't have permission to write packages into the default system-wide location and you will be prompted to create a personal library accessible by your userid. If dependencies are not identified and installed prior to the package's installation, you will see an error similar to:ĮRROR: dependency 'xxx' is not available for package 'yyy'Īs a best practice and to save time, always refer to the package's CRAN site to understand the package dependencies prior to attempting an installation. Package dependencies are listed in the Depends section of the package's CRAN site. Then, install the package using the command R CMD INSTALL:Ī major difference between installing R packages using the R package installer at the R command line and shell command line is that package dependencies must be resolved manually at the shell command line. To install packages this way, first locate the package on CRAN and then download the package source to your local machine. This is useful for some packages when an internet connection is not available or for installing packages not uploaded to CRAN. You can also install R from the shell command line. This is a huge benefit that frees users from the task of identifying and resolving those dependencies. If the arules package depends upon other packages that are not already installed locally, the R installer automatically downloads and installs those required packages.
Within R, using the install.packages function always attempts to install the latest version of the requested package available on CRAN: It installs the arules package as root so that packages are installed in the default R system-wide location where all users can access it, /usr/lib64/R/library. The following example installs a package on Oracle Linux using Oracle R Distribution. R package installation basics are outlined in Chapter 6 of the R Installation and Administration Guide. You can install R packages from the R command line or from your system’s command line.
