TOL+R

From TOL 3.3 onwards, TOL provides a natural communication with R.

Two packages allow us to do than (tolRlink for R) and (TolRInside for TOL).

The title TOL+R represents this set of developments that allows the integration of R in TOL and viceversa.

To take advantage of these functionalities is necessary to perform a proper installation. See below for more details.

Installation

TOL+R requires, besides the both softwares: TOL and R, some additional packages or libraries.

Follow the instrucctions below:

• Install TOL
• Install R
• R packages
• TOL packages

Install TOL

Install TOL (GNU-GCC compiled) version 3.3 onwards (if you have not already done so). See Download.

Environment variables (for Windows)

For the communication with TOL from R is necessary the environment variable TOLGNU_ROOT (TOLGNU_ROOT_64 for TOL 64-bits) containing the TOL 'installation' folder.

• TOL 'installation' folder:
  %PROGRAMFILES%\Tol-Project\tol-gnu-v3.3
  ('program files' folder and version number may be different).

This environment variable is automatically generated during the installation process.

Install R

Install the statistical software R. See ​https://www.r-project.org.

It is recommended R version 3.2 onwards. Specifically R version 3.2.0 has been tried and successfully tested: ​R 3.2.0

If you use TOL 32-bits, you must install (at least) the R 32-bits version.

Environment variables (for Windows)

TOL (for Windows) needs an environment variable named R_HOME containing the R 'installation' folder.

• R 'installation' folder:
  %PROGRAMFILES%\R\R-3.2.0
  (version number may be different)

For example:

SETX R_HOME %PROGRAMFILES%\R\R-3.2.0

Is is also recommended, add R bin folder to the environment variable PATH. This allows some TOL packages (builded before TOL+R) to find R. To do that, you should ensure that the R 'bin' folder is in the environment variable PATH.

• R 'bin' folder:
  %PROGRAMFILES%\R\R-3.2.0\bin
  (version number may be different)

You can edit the environment variable PATH as usual. For example:

SETX PATH %PATH%;%PROGRAMFILES%\R\R-3.2.0

R packages

There are two sets of R-packages used from TOL:

1. The R-packages that TOL uses traditionally from the command line.
   

See: Install some R-packages.

2. The R-packages needed to use TOL from R.
   

See: Rprojects:Installation.

Altogether:

# 1st set
install.packages("quadprog")
install.packages("coda") # imports: lattice
install.packages("mcgibbsit") # depends: coda
install.packages("slam")
install.packages("Rglpk") # depends: slam
# 2nd set
install.packages("lubridate")
install.packages("polynom")
install.packages("base64enc")
# TOL Project developed
install.packages("https://www.tol-project.org/svn/tolp/Rprojects/tolBasis_1.1.zip", repos=NULL, type="binary")
install.packages("https://www.tol-project.org/svn/tolp/Rprojects/tolRlink_1.0.zip", repos=NULL, type="binary")
install.packages("https://www.tol-project.org/svn/tolp/Rprojects/tolKit_1.1.zip", repos=NULL, type="binary")

TOL packages

For the communication from TOL with R there is an only specific package: TolRInside. This can be installed and loaded as usual:

#Require TolRInside;
