R run sweave (Rnw) file from an R script

I would like to run sweave from an R script. The Rnw file is in an Rnw directory just below my project directory. I tried this

system("Rnw/compilePDF.Rnw")

And got this response.

sh: Rnw/compilePDF.Rnw: Permission denied

The permissions on the .Rnw file are -rw-r--r-- but I suspect that is not the issue.

The solution is to include the following bits of code. The encoding is needed because Sweave default is ASCII and returns an error to this effect.

Sweave("Rnw/compilePDF.Rnw", encoding = "UTF-8")

The output of the command is 

Writing to file compilePDF.tex
Processing code chunks with options ...

You can now run (pdf)latex on ‘compilePDF.tex’

To convert this to pdf use 

tools::texi2pdf("Rnw/compilePDF.tex")
