Hi, I like org-mode and org-babel mode very much, but recently I am  having problems outputting R graphics to LaTeX report with Org-Babel mode.  Attached is my test file, where I am generating 4 simple plots of different sizes and format (.png or .pdf).  The HTML export is satisfactory, however, the LaTeX export (C-c C-e l) presents two problems:     1.  All 4 plots have the same size (10em) which is different from the     header specification and is too small. \includegraphics[width=10em]{a1.png} ... \includegraphics[width=10em]{a2.png} ... \includegraphics[width=10em]{a3.pdf} ... \includegraphics[width=10em]{a4.pdf} ...     2. While exporting to PDF file, the R code is mysteriously lost in     the R execution for the PDF output of the plots and the compilation failed correspondingly: > pdf(file="a3.pdf",width=5,height=5) > > dev.off() > pdf(file="a4.pdf",width=10,height=10) > > dev.off() Hopefully you can replicate my errors and help me on this.  Thanks a lot!
