+#+title: How to install R from source in GNU linux distributions
+#+date: 2022-05-28
+
+You may follow the manual on the topic "installing R under Unix-alike".
+
+You can download the source from:
+
+https://cran.r-project.org/sources.html
+
+#+begin_example sh
+  wget https://cran.r-project.org/src/base/R-4/R-4.2.0.tar.gz
+#+end_example
+
+Then, use "tar" to extract the source and build it. Suppose that you are installing
+R 4.2:
+
+#+begin_example sh
+  tar -xf R-4.2.0.tar.gz
+#+end_example
+
+Go to a directory where you will install R. The path shouldn't contain spaces.
+
+#+begin_example sh
+  ./configure
+  make
+#+end_example
+
+#+begin_example sh
+  make check
+#+end_example
+
+If you want to install all the R tree (binaries, manuals, libraries...):
+
+#+begin_example sh
+  make install
+#+end_example
+
+To install packages in R, you can use the function "install.packages()" with the
+name of the file ('...tar.gz') to be installed and the argument "repos" set as "NULL"
+
+You can also install the packages from a shell:
+
+#+begin_example R
+  R CMD INSTALL -l /path/to/library packagename
+#+end_example
