This function is responsible for compiling a version of the R language.
rcompiler(x = NULL, with_blas = NULL, complementary_flags = NULL)Version of R you want to compile. By default (x = NULL) will be compiled the latest stable version of the R
language. For example, x = "3.6.2" will compile and link R-3.6.2 version as the major version on your system.
String, --with-blas = NULL by default, with flags for --with-blas used in the R compilation process.
Details on the use of this flag can be found here.
String, complementary_flags = NULL by default, for adding complementary flags in the R language
compilation process.
Returns a warning message informing you if the procedure occurred correctly. You will also be able to receive information about missing dependencies.
This function is responsible for compiling a version of the R language. The x argument is the version of R that you want to compile.
For example, x = "4.0.0" will compile and link R-4.0.0 version as the major version on your system. By default (x = NULL) will be compiled the latest stable version of the R.
For example, to compile the latest stable version of the R language, do:
rcompiler()Regardless of your GNU/Linux distribution and what version of R is in your repositories, you can have the latest stable version of the R language compiled into your computer architecture.
You can use the rcompiler() function to compile different versions of R. For example, running rcompiler(x = "3.6.3") and rcompiler() will install versions 3.6.3 and 4.0.0 on its GNU/Linux distribution,
respectively. If you are in version 4.0.0 of R and run the code rcompiler(x = "3.6.3") again, the function will identify the existence of version 3.6.3 in the system and give you the option to use the binaries
that were built in a previous compilation. This avoids unnecessarys compilations.
In addition to the x argument, the rcompiler() function has two other arguments that will allow you to change and pass new compilation flags. Are they:
with_blas: This argument sets the --with-blas flag in the R language compilation process and must be passed as a string. Details on the use of this flag
can be found here. If with_blas = NULL (default), then it will be considered:
./configure --prefix=/opt/R/version_r --enable-memory-profiling --enable-R-shlib
--enable-threads=posix --with-blas="-L/opt/OpenBLAS/lib -I/opt/OpenBLAS/include
-lpthread -lm"Most likely, you will have little reason to change this aprgument. Unless you know what you're doing, consider with_blas = NULL. Do not change the installation directory,
that is, always consider --prefix = /opt/R/version_r, where version_r is a valid version of R. For a list of valid versions of
R, run the last_version_r(). Installing R in the /opt/R/version_r directory is important because some
functions in the package require this. Both the R language and the OpenBLAS library will be installed in the /opt directory.
If this directory does not exist in your GNU/Linux distribution, it will be created;
complementary_flags: String (complementary_flags = NULL by default) for adding complementary flags in the R language compilation process.
Passing a string to complementary_flags will compile it in the form:
./configure --with-blas="..." complementary_flags# rcompiler()
