Setting up a R Development Environment for Windows

[jussij]

NOTE: It is strongly recommended usign the lastest Zeus IDE found here: https://www.zeusedit.com/download.html

That latest version comes with a R Document Type definition, but users of older versions can still manually create that definition.

Setting up a R Development Environment for Windows
The R mome page is found here: https://www.r-project.org/

Download and run the Windows installer is found here: https://cran.r-project.org/bin/windows/base/

NOTE: At the time of writing the R-4.3.1 for Windows (79 megabytes, 64 bit) installer was used for this test.

Setting up the PATH
That 64 bit installer defaults to installing to this folder location:

Code: Select all

C:\Program Files\R\R-4.3.1\bin

Before the software can be used this location needs to be added to PATH environment variable.

For information on how to do this refer to the following link: viewtopic.php?t=6176

Testing the Setup
After making the PATH changes, start the Zeus IDE and use the Tools, DOS Command Line menu to run the following command:

Code: Select all

Rscript.exe --version

Running that command should result in the following output:

Code: Select all

---------------------------------------------------------------------------
      Zeus IDE - Version 3.99am
      Copyright (c) Xidicone P/L 2023  All rights reserved.
---------------------------------------------------------------------------

Rscript (R) version 4.3.1 (2023-06-16)

If that output is not produced check the path settings made earlier to make sure they are correct.

Creating a R Program
With the Zeus IDE installed, select the R Template option as shown below:

The attachment R-template.png is no longer available

Create a new test.r file usign the code shown below:

Code: Select all

hello <- function( name ) {
    sprintf( "Hello, %s", name );
}
hello("world")

With that file as the active document use the Macros, Execute menu to run this script as shown in the image below:

r-run.jpg (111.28 KiB) Viewed 23044 times

The running of that script will result in the following tool output window:

r-execute.jpg (88.81999999999999 KiB) Viewed 23046 times

Creating a R Grapical Program

Consider this test.r file that creates a graph using the plot function:

Code: Select all

# NOTE: The plot function creates a file called Rplots.pdf
x <- seq(-2*pi,2*pi,0.1)
plot(x, sin(x))

Running that R script using the Macros, Execute menu creates a PDF graph file and the macro will display that file in the browser as shown below:

r-plot.jpg (121.56 KiB) Viewed 23040 times

NOTE: For details on how this works refer to the Zeus r_exec.lua found in the zScript folder.
