+  By default, \file{Sweave.sty} sets the width of all included graphics to:
+
+  \code{\\setkeys{Gin}{width=0.8\\textwidth}}
+
+  You can adjust this by including the above in your .Rnw file after the
+  \code{\\begin{document}} directive and adjust the \code{width}
+  parameter above accordingly. Note that this parameter determines the actual
+  graphic dimensions in your final document and therefore overrides the
+  \code{height} and \code{width} options that you may use in each
+  figure chunk or have set globally. The \code{height} and \code{width}
+  options will determine the dimensions of the runtime generated
+  PDF and EPS files created in this setting.
+
+  If you wish to override this default behavior, you can use
+  \code{\\usepackage[nogin]{Sweave}} in your preamble. In this case, the
+  \code{height} and \code{width} options will determine the runtime
+  generated graphic file sizes and the size of the graphics in your
+  final document.
+
+  \file{Sweave.sty} also supports the \code{[noae]} option, which
+  suppresses the use of the \code{ae} package, the use of which may
+  interfere with certain encoding and typeface selections. If you have
+  problems in the rendering of certain character sets, try this option.
