R running with Command Line Error: '\U' used without hex digits in character string starting "'C:\U"
<p>I am using R just to plot graph calculated from another executable jar file(vdjtools-1.0.7) compiled into Java.</p>

<p>For example when I run into the Command Line:</p>

<p><code>C:\Users\Lucy\Desktop\mixcr-1.7.1\R\R-3.2.4revised\bin\java –Xmx3g –jar vdjtools-1.0.7.jar PlotFancySpectratype inputFile.txt outputFile</code></p>

<p>It runs the program vdjtools properly because I have a correct output txt file but it doesn’t give a pdf file generated by R with the plot like it should:</p>

<blockquote>
  <p>...[Fri Apr 01 12:00:58 CEST 2016 PlotFancySpectratype] Writing output and plotting data</p>

  <p>[ERROR] Erreur : '\U' non suivi de chiffres hexadécimaux dans la chaîne de caractères débutant ""C:\U"
  Exécution arrêtée</p>
</blockquote>

<p>I know that R doesn’t like ‘\’ and it should be instead ‘/’ or ‘\’ but when I write the path to directory with ‘/’ or ‘\’ into the command line, it gives the same result..</p>

<p>Hope someone can help me..</p>
