RHEL7でR言語を利用できる環境を用意する。
環境
Google Cloud Platform環境のVMインスタンス
$ cat /etc/os-release NAME="Red Hat Enterprise Linux Server" VERSION="7.6 (Maipo)" $ arch x86_64
手順
R言語をインストール
yumコマンドでインストールをおこないます。
まずはyum infoで情報を確認します。
# yum info R
Available Packages
Name : R
Arch : x86_64
Version : 3.5.2
Release : 2.el7
Size : 30 k
Repo : epel/x86_64
Summary : A language for data analysis and graphics
URL : http://www.r-project.org
License : GPLv2+
Description : This is a metapackage that provides both core R userspace and
: all R development components.
:
: R is a language and environment for statistical computing and
: graphics. R is similar to the award-winning S system, which was
: developed at Bell Laboratories by John Chambers et al. It provides
: a wide variety of statistical and graphical techniques (linear and
: nonlinear modelling, statistical tests, time series analysis,
: classification, clustering, ...).
:
: R is designed as a true computer language with control-flow
: constructions for iteration and alternation, and it allows users
: to add additional functionality by defining new functions. For
: computationally intensive tasks, C, C++ and Fortran code can be
: linked and called at run time.リポジトリに存在が確認できたのでインストールを行います。
# yum -y install R Resolving Dependencies --> Running transaction check ... Installed: R.x86_64 0:3.5.2-2.el7 ... Complete!
インストール後はwhichコマンドでRのパスを確認します。
# which R /usr/bin/R
Rの起動確認
# R
で起動
q()
で終了できます。
以下のように起動終了画面が出ます。

必要なパッケージはinstall.packagesで行えます。
初めて実施すると以下のようにミラーサイトを指定します。
今回は日本のミラーサイトを選びました。

HelloWorld
R言語はスクリプト言語なので、Rが起動した状態で以下のようにコマンド押下すればHelloWorldを表示できます。
> print("Helloworld")
[1] "Helloworld"またviなどで以下のようなファイルを.r形式で用意して
# cat hello.r print("Helloworld")
R言語起動後にsource関数で起動
> source("hello.r")
[1] "Helloworld"またはコマンドラインから直接起動も可能です。
# R --vanilla --slave < hello.r [1] "Helloworld"
以上、Linux環境にR言語をインストールした際の備忘録でした。
