Dear all,

When I try to build a Windows binary in RStudio using R-devel, 
everything goes well until the packages is tested whether it can be 
loaded. I then get the error:

** testing if installed package can be loaded *** arch - i386 Error: 
'\U' used without hex digits in character string starting "'C:\U" 
Execution halted *** arch - x64 Error: '\U' used without hex digits in 
character string starting "'C:\U" Execution halted ERROR: loading failed 
for 'i386', 'x64' * removing 
'C:\Users\rampa\AppData\Local\Temp\Rtmp0o1Fm1\temp_libpath1cd445c31688/SADISA' 
Error: Command failed (1) Execution halted Exited with status 1.


I have updated RStudio, Rtools and Rdevel,and the problem persists. Does 
anyone have a clue how to solve this?

Before I updated to the newest Rdevel, everything worked fine.

Kind regards, Rampal Etienne

That looks like a bug.  It's in R, not RStudio.  To reproduce, start 
cmd.exe, and switch to a directory containing a source tarball or a 
source directory, and run

R CMD INSTALL --build <tarball>

For instance, when I do that with the tables package, I get

D:\svn\MyR>R CMD INSTALL --build tables
* installing to library 'f:\cygwin\home\murdoch\R\win-library\3.4'
* installing *source* package 'tables' ...

** preparing package for lazy loading
** help

** building package indices
** installing vignettes
** testing if installed package can be loaded
Error: '\c' is an unrecognized escape in character string starting "'f:\c"
Execution halted
ERROR: loading failed
* removing 'f:\cygwin\home\murdoch\R\win-library\3.4/tables'
* restoring previous 'f:\cygwin\home\murdoch\R\win-library\3.4/tables'

It appears that the script is building paths including unescaped 
backslashes when it constructs the library path.  You can probably work 
around it by specifying the library path explicitly.  Since you were 
installing into a temporary library, that's a little tricky, but for 
most people it should be easy.

I'll see if I can track it down and fix it.

Indeed, it is also fairly new, as I typically do manual stuff that way 
and it hit me 5 minuites ago. Sorry for not having tested it as I did 
not believe there was a newly introduced bug.
