<div dir="ltr">I'm resurrecting a thread from back in October (month 10--two digits--this is of consequence).  My challenge was this:<br><br>I am using R and Sweave and MikTeX on Windows 7.  I use this workflow<br>
to generate a recurring report quarterly. Same report, just new data.<br>

including <span class="gmail-il">the</span> <span class="gmail-il">system date</span>., like this:<br><br><timeseriesplot, results=hide, echo=FALSE>>=<br>
