[Rd] Checking package vignettes: WARNING

[Arne Henningsen]

Hi,

I want to have a "vignette" in one of my R packages. Hence, I added an Sweave 
file into the /inst/doc subdirectory of this package. Unfortunately, 'R CMD 
check' gives a warning:

==========================================
[...]
* checking tests ... OK
* checking package vignettes in 'inst/doc' ... WARNING
--- führe texi2dvi auf Vignetten aus
* creating sampleSelection-manual.tex ... OK
* checking sampleSelection-manual.tex using pdflatex ... OK

WARNING: There was 1 warning, see
  /home/suapm095/Documents/Econometrics/R/micEcon/micEcon/sampleSelection.Rcheck/00check.log
for details
==========================================

Since the line below "WARNING" is in German, I ran 'LC_ALL="C" R CMD check' 
to get an English message (which I could use in a Google search). However, the 
warning does NOT occur if I run 'R CMD check' in the 'C' locale. I tried a 
lot of different things and I figured out that 'führe texi2dvi auf Vignetten 
aus' is the translation of 'running texi2dvi on vignettes', but I did not 
find the reason for the warning message that occurs if 'R CMD check' is run 
in the German locale. If I run Sweave and texi2dvi by hand with both locales, 
the only possibly relevant difference I noticed is that Sweave uses straight 
single quotation marks in the 'C' locale but (italicized) primes in the 
German locale:

'C' locale:
   Signif. codes:  0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1 

German locale:
   Signif. codes:  0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1 

System Information:
R 2.7.1
i486-pc-linux-gnu
Kubuntu 8.04 

Any hints are welcome!
Thanks,
Arne
