title: Julia in R (JuliaCall and XRJulia not working with Julia 0.7 or newer)
body: <p>I am trying hard to make julia work through R but i am not being successful. I followed the instructions from <a href="https://stackoverflow.com/questions/9965747/linking-r-and-julia">here</a>, <a href="https://stackoverflow.com/questions/47213269/xrjulia-and-findjulia">here</a> and <a href="https://stackoverflow.com/questions/46827110/finding-julia-in-r">here</a> with no success. I added <code>Julia</code> to the path and installed and tested in <code>Julia</code> both <code>RCall</code> and <code>JSON</code> packages. I don't know what else to do T_T!</p>
  
  <p>With <code>JuliaCall</code> i get the following error:</p>
  
  <pre><code>&gt; julia &lt;- julia_setup()
  Julia version 0.7.0 at location C:\Users\ModellT\AppData\Local\JULIA_~1\bin will be used.
  Error in inDL(x, as.logical(local), as.logical(now), ...) : 
    character argument expected
  </code></pre>
  
  <p>With <code>XRJulia</code>: </p>
  
  <pre><code>&gt; findJulia()
  [1] "C:\\Users\\ModellT\\AppData\\Local\\Julia_0_7\\bin\\julia.exe"
  &gt; findJulia(test = T)
  [1] FALSE
  </code></pre>
