Parallel package is not available in R 3.3.1 (Ubuntu 14.04)
<p>I'm doing some heavy work with my computer. I'd like R used the 4 processors . But, used one at a time. I think the parallel package can be useful, but is not available. What I can do?</p>

<p>When I try to install the following appears</p>

<pre><code>&gt; install.packages("parallel")
Installing package into ‘/home/hector/R/x86_64-pc-linux-gnu-library/3.3’
Warning in install.packages :
  package ‘parallel’ is not available (for R version 3.3.1)
Warning in install.packages :
  package ‘parallel’ is a base package, and should not be updated
