[R] Passing tex parameter via texi2dvi

[Dieter Menne]

I am trying to pass a additional argument to texi2dvi, for example to use
the aux-directory. Looks like this is not possible via options:

options(texi2dvi='texi2dvi --tex-option="-aux-directory=auxdir"')
texi2dvi(file = "GBPL3.tex", pdf = TRUE)

#Error in system(paste(shQuote(texi2dvi), "--version"), intern = TRUE) : 
#  '"texi2dvi --tex-option=\"-aux-directory=auxdir\""' not found

Because --version come in the way, and extra is there, but not really used.
	
     extra <- ""
#### ??? --version does not like tex-options
        ver <- system(paste(shQuote(texi2dvi), "--version"), 
            intern = TRUE)
        if (length(grep("MiKTeX", ver[1L]))) {
            texinputs <- c(texinputs0, Rtexinputs, Rbstinputs)
            texinputs <- gsub("\\", "/", texinputs, fixed = TRUE)
            paths <- paste("-I", shQuote(texinputs))

            extra <- paste(extra, paste(paths, collapse = " "))
        }
   
Is there any other workaround beside copy/change/rename/paste of texi2dvi?
