title: Write two R output data in a same excel spreadsheet
body: <p>I am a beginner in R and I would like to write output data composed of two matrices with column and row names from each one in a same excel spreadsheet. 
  I tried to concatenate the two matrices that have the same dimension but I failed. </p>

    <p><strong>Edit:</strong> I can't install XLConnect. Actually I'm not allowed to install any
    package in the computer in which I am working. Does anyone know an
    alternative method to the one proposed by @nrussell producing the same output ?</p>
