title: Error: package or namespace load failed for XLConnect
body: <p>I'm installing XLConnect library in R studio but, unable to do so.</p>
  <p>I know that this package has java dependency and my R software and java both are 64 bit.
  Also, both have configured correctly.
  I have also installed rJava package before installing XLConnect.
  This package was working properly but, now I'm getting this error.</p>
  <pre><code>library(XLConnect)
