Parallel Workers Running MS Windows via Wine

Introduction

This vignette shows how to set up parallel workers running R for MS Windows via Wine (https://www.winehq.org/) on Linux and macOS. This can be useful when we need to run R code or call R packages that work only on MS Windows.

The below instructions assume that you already have Wine installed.

Install R for MS Windows 11

To install R for MS Windows in Wine, first configure Wine to use Windows 11;

$ winecfg /v win11
$ winecfg /v
win11

Then, install R for Windows in Wine, by:

$ wget https://cran.r-project.org/bin/windows/base/R-4.5.2-win.exe
$ wine R-4.5.2-win.exe /SILENT

Finally, verify that R is available in Wine;

$ wine "C:/Program Files/R/R-4.5.2/bin/x64/Rscript.exe" --version
...
Rscript (R) version 4.5.2 (2025-10-31)

Examples

Example: Parallel workers running MS Windows via Wine

This example shows how to launch one worker running in Wine for Linux on the local machine.

cl <- makeClusterPSOCK(
  1L,
  rscript = c(
    ## Silence Wine warnings
    "WINEDEBUG=fixme-all",
    "LC_ALL=en_US.UTF-8",
    ## 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-4.5.2/bin/x64/Rscript.exe"
  )
)
print(cl)
#> Socket cluster with 1 node on host 'localhost'
#> (R version 4.5.2 (2025-10-31 ucrt), platform x86_64-w64-mingw32)

Appendix

Wine and R warnings

It might be that Wine produces warnings like:

0128:fixme:font:find_matching_face Untranslated charset 255

and R for Windows produces a warning on:

During startup - Warning message:
Using locale code page other than 65001 ("UTF-8") may cause problems.

These are typically harmless. Environment variable setting WINEDEBUG=fixme-all should take care of the first one, and LC_ALL=en_US.UTF-8 the second one.

Windows-only CRAN packages

A small number of the CRAN packages install only on MS Windows. Here is how to see which are:

db <- read.dcf(url("https://cran.r-project.org/src/contrib/PACKAGES"))
db <- as.data.frame(db)
win_only <- subset(db, OS_type == "windows")
print(win_only$Package)

As of 2026-01-21, this outputs:

 [1] "BiplotGUI"         "blatr"             "excel.link"
 [4] "KeyboardSimulator" "MDSGUI"            "MediaNews"
 [7] "R2PPT"             "R2wd"              "rFUSION"
[10] "RWinEdt"           "spectrino"         "taskscheduleR"
