Procedure

1. Use PuTTY to log in to the server as the root user.
2. Download the R language source package.

   cd /path/to/bioconductor-ebcoexpress
   wget https://cran.r-project.org/src/base/R-4/R-4.2.0.tar.gz

3. Decompress the installation package.

   tar xvf R-4.2.0.tar.gz

5. Install the dependencies using the yum command.

   yum install libXt-devel libX11-devel readline-devel

6. Compile and install R.

   ./configure --prefix=/path/to/bioconductor-ebcoexpress/R_install
   make
   make install

7. Load the environment variables.

   export PATH=/path/to/bioconductor-ebcoexpress/R_install/bin:$PATH
   export LD_LIBRARY_PATH=/path/to/bioconductor-ebcoexpress/R_install/lib/R/library:$LD_LIBRARY_PATH

8. (Optional) If the network speed is slow, add a mirror source of the R language.
   1. Open the ~/.Rprofile file.

      vim ~/.Rprofile
