title: Installation error with RDCOMClient in RSTUDIO
body: <p>I´m trying to install the RDCOMClient package in rstudio in order to use the R2PPT package to create power point presentations.</p>
  
  <p>I search and the instruction to install RDCOMClient package is:</p>
  
  <p><em>install.packages("RDCOMClient", repos = "<a href="http://www.omegahat.org/R" rel="noreferrer">http://www.omegahat.org/R</a>")</em></p>
  
  <p>The problem is that the reposotory webpage is not available anymore.</p>
  
  <p>does anyone know how to install the RDCOMClient or use R2PPT without RDCOMClient package?</p>
