title: Specify package location in foreach
body: <p>I am installing a package to a particular directory and then loading in the library using:</p>
  
  <pre><code>library(CustomPackage, lib.loc = "R_Libs")
  </code></pre>
  
  <p>Then when using foreach I am having trouble figuring out how to load this one package from that custom location "R_Libs".</p>
  
  <pre><code>foreach(i=(1:100), .packages=c("lubridate","CustomPackage")) %dopar% {
  some code here...
  }
  </code></pre>
  
  <p>Any ideas how to force that one package to be read from the "R_Libs" directory?</p>
