Re: [R-pkg-devel] [r-package-devel] Win.Metafile and package check - "Found the platform-specific device:"

[Wayne.W.Jones]

Update:

I noticed in the ggplot2 codebase they also have a call to win.metafile - see 
https://github.com/tidyverse/ggplot2/blob/main/R/save.R#L280-L281

When I use grDevices::win.metafile instead of win.metafile it passes the local 
checks fine.

Hi Vladimir,

Thanks for the suggestions. I've considered both but I can't see a way of doing 
what I'm trying to achieve without explicitly adding a call to win.metafile in 
my code.

To explain a little more...

GWSDAT is a Shiny App so we don't use the traditional R graphics device - so 
your suggestion #1 is not an option . Instead, the user is offered a range of 
different plot options in a shiny list box as illustrated here in this windows 
based example:
https://user-images.githubusercontent.com/61183826/280452267-c4287f8d-73cc-42a3-881a-4643bdb31689.png

The list of options presented to the users in the list box is modified 
according to the platform - see code here:  
https://github.com/WayneGitShell/GWSDAT/blob/master/R/server.R#L117-L118

So anyone using a non-windows platform will never be offered the choice of 
"wmf"  to begin with. For example, see the online LINUX  version, 
https://stats-glasgow.shinyapps.io/GWSDATV3-2/.  You will see that this option 
doesn't exist in the list of choices - see 
https://user-images.githubusercontent.com/61183826/280453275-6da9b235-0387-47fd-b3a8-b0a949f0ec3e.png

Any suggestions on how I can modify this approach to make it automatically pass 
the CRAN checks?

Thanks,

Wayne

Two suggestions:

   * let users specify the graphics device they want

   * reading manpage for dev.new() it accepts a bunch of options - there is 
probably a way to request the metafile device you want. But I could not find 
that in documentation.

[R-pkg-devel] [r-package-devel] Win.Metafile and package check - "Found the platform-specific device:"

[Wayne.W.Jones]

Dear R-Package-Devel,

As part of GWSDAT package (https://github.com/waynegitshell/GWSDAT) we support 
the option to output plots to a WMF 
(https://r-graphics.org/recipe-output-vector-wmf) format if, and only if,  the 
user is on Windows. However, when I run the package checks on here it complains 
about using a platform specific function with the following message:

  Found the platform-specific device:
'win.metafile'
  dev.new() is the preferred way to open a new device, in the unlikely
  event one is needed.

In my opinion this is a false positive - and a similar issue has previously 
been reported here: 
https://stackoverflow.com/questions/70585796/unable-to-understand-1-note-in-devtoolscheck-caused-by-a-platform-specific-d

Any ideas on how I modify the code and package submission to automatically pass 
the checks?

Thanks,

Wayne

[Rd] Windows R-3.0.0 and Tcl/tkrplot issue

[Wayne.W.Jones]

Greetings R Developers,

I've been testing the alpha release of R-3.0.0 and I noticed that the plotting 
functionality in package tkrplot was not working correctly.
Further diagnosis found the issue to be related to the command '.Tcl(image 
create Rplot plotname)' from package tkrplot.

The following example is  taken from here:  
http://tkrplot.sourcearchive.com/documentation/0.0.14/tcltkimg_8c_source.html

 library(tkrplot)
 library(tcltk)
 my.tkdev - function() win.metafile(width=4,height=4)
 my.tkdev()
 plot(1:20)
 .Tcl(image create Rplot fred)
Error in structure(.External(.C_dotTcl, ...), class = tclObj) :
  [tcl] can't get device image.

This example works fine in R-2.15.3.  I've emailed the package maintainer Luke 
Tierney but unfortunately he doesn't have the ability to build and test 
packages on windows.
Can anyone elucidate what tcltk changes have been made in moving to R-3.0.0?

Details of installation are as follows:

 version
platform   i386-w64-mingw32
arch   i386
os mingw32
system i386, mingw32
status alpha
major  3
minor  0.0
year   2013
month  03
day16
svn rev62282
language   R
version.string R version 3.0.0 alpha (2013-03-16 r62282)
nickname   Unsuffered Consequences


Thanks,

Wayne
