title: Using R with Jupyter notebook installation
body: <p>I have installed R from the official site and want to use it from jupyter notebook and jupyterlab. For that i have installed IRkernal in R using:</p>
  <pre class="lang-r prettyprint-override"><code>install.packages('IRkernel')
  </code></pre>
  <p>and then when I type <code>IRkernel::installspec(user = FALSE)</code> to make this installation visible globally,
  I get following error:</p>
  <pre class="lang-r prettyprint-override"><code>Error in IRkernel::installspec(user = FALSE) : 
    jupyter-client has to be installed but “jupyter kernelspec --version” exited with code 127.
  In addition: Warning message:
  In system2(&quot;jupyter&quot;, c(&quot;kernelspec&quot;, &quot;--version&quot;), FALSE, FALSE) :
    '&quot;jupyter&quot;' not found
  </code></pre>
  <p>I have jupyter installation on miniconda and I don't want to use the conda distribution of R. What should I do?</p>
