[R] Sweave

[R Heberto Ghezzo, Dr]

Thanks to Prof Ripley, I modified Rprofile.site with:

.First <- function() {
 Sys.setenv("JAGS_HOME"=replace.substring.wild(R.home(), "R-*", "JAGS-1.0.3"))
Sys.setenv("LATEX"=replace.substring.wild(R.home(),"R*","PortableUSB/PortableApps/MikeTex/miktex/bin/latex.exe"))
PathNew <- paste(Sys.getenv("PATH"),";",replace.substring.wild(R.home(),"R*","PortableUSB/PortableApps/MikeTex/miktex/bin"),sep="")
 Sys.setenv("PATH"=PathNew)
 }

 Sorry I mispelled MikTex with MikeTex!!, it is MixTex Portable
 but now I get

misspelled it (e.g., `\hobx'), type `I' and the correct

I've deleted a group-closing symbol because it seems to be
spurious, as in `$x}$'. But perhaps the } is legitimate and
you forgot something else, as in `\hbox{$x}'. In such cases
the way to recover is to insert both the forgotten and the
