如何让linux识别R的位置

Question

我确信这是一个微不足道的问题，但我试图在Linux中安装多个R版本。我不是使用R工作室服务器pro，而是使用免费的R工作室服务器。我跟踪这个文档来安装R，但是当我试图定位它时却发现了错误。但是，当我运行一个命令来查看安装了哪个版本的R时，没有出现错误。

R安装好了！

(base) noah@noah-VirtualBox:/opt/R/4.1.3$  /opt/R/4.1.3/bin/R --version
R version 4.1.3 (2022-03-10) -- "One Push-Up"

尝试

(base) noah@noah-VirtualBox:/opt/R/4.1.3$ R

Command 'R' not found, but can be installed with:

sudo apt install r-base-core

(base) noah@noah-VirtualBox:/opt/R/4.1.3$ which R
(base) noah@noah-VirtualBox:/opt/R/4.1.3$ 

复制步骤

export R_VERSION=4.1.3

curl -O https://cran.rstudio.com/src/base/R-4/R-${R_VERSION}.tar.gz
tar -xzvf R-${R_VERSION}.tar.gz
cd R-${R_VERSION}

# Build and install R
./configure \
    --prefix=/opt/R/${R_VERSION} \
    --enable-memory-profiling \
    --enable-R-shlib \
    --with-blas \
    --with-lapack

make
sudo make install

# Verify R installation
/opt/R/${R_VERSION}/bin/R --version

# Create a symlink to R
sudo ln -s /opt/R/${R_VERSION}/bin/R /usr/local/bin/R
sudo ln -s /opt/R/${R_VERSION}/bin/Rscript /usr/local/bin/Rscript

# Export path so Rstudio can find it
export RSTUDIO_WHICH_R='/opt/R/4.1.3/bin'

你搞得太复杂了。只需安装，比如说，

/opt/R/4.2.0/
/opt/R/4.1.2/
/opt/R/4.0.5/

然后将$PATH设置为您想要的版本中的bin/目录，或者直接调用R。这正是我们很多人对R的两个版本(即R-release和R-devel)所做的：

$ R --version | head -1
R version 4.2.0 (2022-04-22) -- "Vigorous Calisthenics"
$ 
$ /usr/lib/R/bin/R --version | head -1
R version 4.2.0 (2022-04-22) -- "Vigorous Calisthenics"
$ 
$ /usr/local/lib/R-devel/bin/R --version | head -1
R Under development (unstable) (2022-05-24 r82398) -- "Unsuffered Consequences"
$ 

前两个是相同的，因为这是我的‘默认’版本。第三位是我的另一位。这就是它的全部。
