<h1>Introduction</h1>
<p>This vignette shows how to set up parallel workers running on MS
Windows via Wine (<a href="https://www.winehq.org/">https://www.winehq.org/</a>) on Linux and macOS.</p>
<h2>Install R for MS Windows 10</h2>
<p>To install R for MS Windows in Wine, first configure Wine to use
Windows 10;</p>
<pre><code class="language-sh">$ winecfg
</code></pre>
<p>In the GUI, set ‘Windows version’ to ‘Windows 10’. Then, install R for
Windows in Wine, by:</p>
<pre><code class="language-sh">$ wget https://cran.r-project.org/bin/windows/base/R-4.4.2-win.exe
$ wine R-4.4.2-win.exe /SILENT
</code></pre>
<p>Finally, verify that R is available in Wine;</p>
<pre><code class="language-sh">$ wine "C:/Program Files/R/R-4.4.2/bin/x64/Rscript.exe" --version
...
Rscript (R) version 4.4.2 (2024-10-31)
</code></pre>
<h1>Examples</h1>
<h2>Example: Parallel workers running MS Windows via Wine</h2>
<p>This example shows how to launch one worker running in Wine for Linux
on the local machine.</p>
<pre><code class="language-r">cl <- makeClusterPSOCK(
1L,
rscript = c(
## Silence Wine warnings
"WINEDEBUG=fixme-all",
## Don't pass LC_* and R_LIBS* environments from host to Wine
sprintf("%s=", grep("^(LC_|R_LIBS)", names(Sys.getenv()), value = TRUE)),
"wine",
"C:/Program Files/R/R-4.4.2/bin/x64/Rscript.exe"
)
)
print(cl)
#> Socket cluster with 1 nodes where 1 node is on host 'localhost'
#> (R version 4.4.2 (2024-10-31 ucrt), platform x86_64-w64-mingw32)
</code></pre>
