Hi, I think the problem came from the explicit argument "--args" when running Rscript; it should not be there. You can remove it and try again.
Tools-->Preferences-->Converters; find Sweave to LaTeX (whatever); then modify the converter (remove "--args"). The presence of "--args" will make ls.args[4] to be ISO-8859-15, which is obviously not a directory name.
