title: Why does installed "igraph" package return "libicui18n.so.58: cannot open shared object file"after loading?
body: <p>I was trying to install the package igraph in R using the command install.packages(&quot;igraph&quot;). After the installation, during testing phase it showed the following error:</p>
  <blockquote>
  <p>testing if installed package can be loaded Error: package or namespace
  load failed for ‘igraph’ in dyn.load(file, DLLpath = DLLpath, ...):<br />
  unable to load shared object
  '/home/midhun/R/x86_64-redhat-linux-gnu-library/3.5/igraph/libs/igraph.so':
  libicui18n.so.58: cannot open shared object file: No such file or
  directory   Error: loading failed   Execution halted   ERROR: loading
  failed</p>
  <ul>
  <li>removing ‘/home/midhun/R/x86_64-redhat-linux-gnu-library/3.5/igraph’</li>
  </ul>
  <p>The downloaded source packages are in<br />
  ‘/tmp/RtmpLVDism/downloaded_packages’   Warning message:   In
  install.packages(&quot;igraph&quot;) :     installation of package ‘igraph’ had
  non-zero exit status</p>
  </blockquote>
  <p>Why this is happening? What could be a solution?</p>
