How does java generate R boxplot via RCaller? -

I want to generate R boxplot by using rcaller with java. My code is:

  Try {RCaller caller = new RCaller (); Caller.setRExecutable ("/ usr / bin / r"); Caller.setGraphicsTheme (new default theme) ()); Encoded code = new encoded (); Code.clear (); File file = code.startplate (); Code.addRCode ("boxplot ((1:10), main = \" 1-10 \ ");); Println (code.toString ()); Code.endPlot (); Caller.setRCode (code); Caller.runAndReturnResultOnline ("boxplot (1:10), main = \" 1-10 \ ""); Code.showPlot (file);   
 But this code does not run on the  caller.runAndReturnResultOnline ("boxplot (1:10), main = \" 1-10 \ "");   
 I try to use the code given below, which can plot R Plot. What is the difference between them?  
  try {RCaller caller = new RCaller (); Caller.setRExecutable ("/ usr / bin / r"); Caller.setGraphicsTheme (new default theme) ()); Encoded code = new encoded (); Code.clear (); Double [] number = new double [] {1, 4, 4, 5, 6, 10}; Code.addDoubleArray ("x", number); File file = code.startplate (); Println (file.toString ()); Code.addRCode ("plot.ts (x)"); Println (code.toString ()); Code.endPlot (); Caller.setRCode (code); Caller.runAndReturnResultOnline ("plot.ts (x)"); Code.showPlot (file); Change your line:  
  code.addRCode ("Boxplot ((1:10), main = \" 1-10 \ "););   
 From:  
  code.addRCode ("boxplot (c (1:10), main = '1-10');); Or as another example, you can give your X vector to Java and change this line:  
  caller.runAndReturnResultOnline ("plot.ts (x ) ");   
 by  
  caller.runAndReturnResultOnline ("boxplot (x)");   
  PS: I do not have Java for testing.
