title: R and Julia Kernels not available in Jupyter notebook
body: <p>I recently installed the Anaconda3 distribution and I want to have the R and Julia Kernels available besides Python. I use windows 10.</p>
  
  <p>To install IJulia I installed the Julia language and follewed the steps indicated in the <a href="https://github.com/JuliaLang/IJulia.jl" rel="noreferrer">IJulia page</a>; everything went fine. </p>
  
  <p>To install the R kernel I used the command <code>conda install -c r r-essentials</code> in the anaconda command prompt, again, no problems. I also installed R. </p>
  
  <p>When I launch the notebook <strong>the only available kernel is Python</strong>, the R and Julia kernels doesn't appear in the list, I have no clue why this since I got no errors in the installation of IJulia and IRKernel. Anyone could help?</p>
