title: Cannot install library(xlsx) in R and look for an alternative
body: <p>I use R version 3.0.3. I was not able to install library(xlsx). Error message:</p>
  
  <pre><code>Loading required package: rJava
  Error : .onLoad failed in loadNamespace() for 'rJava', details:
  call: inDL(x, as.logical(local), as.logical(now), ...)
  error: unable to load shared object 'C:/Program Files/R/R-3.0.3/library/rJava/libs/x64/rJava.dll':
  
  LoadLibrary failure:  The specified module could not be found.
  </code></pre>
  
  <p>I then tried to install <code>rjava</code> on its own. Got the error message below:</p>
  
  <blockquote>
    <p>library("rJava", lib.loc="C:/Program Files/R/R-3.0.3/library")
    Error : .onLoad failed in loadNamespace() for 'rJava', details:
      call: inDL(x, as.logical(local), as.logical(now), ...)
      error: unable to load shared object 'C:/Program Files/R/R-3.0.3/library/rJava/libs/x64/rJava.dll':
      LoadLibrary failure:  The specified module could not be found.</p>

  <p>Is there another way to load excel file in R?</p>
  
  <p>Thanks,</p>
