Constructor Detail

Rengine

public Rengine(java.lang.String[] args,
               boolean runMainLoop,
               RMainLoopCallbacks initialCallbacks)

Method Detail

getVersion

public static long getVersion()

version of the Rengine itself; see also rniGetVersion() for binary version. It's a good idea for the calling program to check the versions of both and abort if they don't match

versionCheck

public static boolean versionCheck()

getMainEngine

public static Rengine getMainEngine()

rniSetupR

public int rniSetupR(java.lang.String[] args)

rniParse

public long rniParse(java.lang.String s,
                     int parts)

rniEval

public long rniEval(long exp,
                    long rho)

rniGetString

public java.lang.String rniGetString(long exp)

rniGetStringArray

public java.lang.String[] rniGetStringArray(long exp)

rniGetIntArray

public int[] rniGetIntArray(long exp)

rniGetDoubleArray

public double[] rniGetDoubleArray(long exp)

rniGetVector

public long[] rniGetVector(long exp)

rniPutString

public long rniPutString(java.lang.String s)

rniPutStringArray

public long rniPutStringArray(java.lang.String[] a)

rniPutIntArray

public long rniPutIntArray(int[] a)

rniPutDoubleArray

public long rniPutDoubleArray(double[] a)

rniPutVector

public long rniPutVector(long[] exps)

rniGetAttr

public long rniGetAttr(long exp,
                       java.lang.String name)

rniSetAttr

public void rniSetAttr(long exp,
                       java.lang.String name,
                       long attr)

rniCons

public long rniCons(long head,
                    long tail)

rniCAR

public long rniCAR(long exp)

rniCDR

public long rniCDR(long exp)

rniPutList

public long rniPutList(long[] cont)

rniGetList

public long[] rniGetList(long exp)

rniGetVersion

public static long rniGetVersion()

rniStop

public int rniStop(int flag)

rniAssign

public void rniAssign(java.lang.String name,
                      long exp,
                      long rho)

rniExpType

public int rniExpType(long exp)

rniRunMainLoop

public void rniRunMainLoop()

rniIdle

public void rniIdle()

addMainLoopCallbacks

public void addMainLoopCallbacks(RMainLoopCallbacks c)

startMainLoop

public void startMainLoop()

if Rengine was initialized with runMainLoop=false then this method can be used to start the main loop at a later point. It has no effect if the loop is running already. This method returns immediately but the loop will be started once the engine is ready.

jriWriteConsole

public void jriWriteConsole(java.lang.String text)

jriBusy

public void jriBusy(int which)

jriReadConsole

public java.lang.String jriReadConsole(java.lang.String prompt,
                                       int addToHistory)

jriShowMessage

public void jriShowMessage(java.lang.String message)

jriLoadHistory

public void jriLoadHistory(java.lang.String filename)

jriSaveHistory

public void jriSaveHistory(java.lang.String filename)

jriChooseFile

public java.lang.String jriChooseFile(int newFile)

jriFlushConsole

public void jriFlushConsole()

eval

public REXP eval(java.lang.String s)

idleEval

public REXP idleEval(java.lang.String s)

This method is very much like eval(String), except that it is non-blocking and return null if the engine is busy.

Parameters:

s - string to evaluate

Returns:

result of the evaluation or null if the engine is busy

waitForR

public boolean waitForR()

end

public void end()

run

public void run()

Specified by:

run in interface java.lang.Runnable

Overrides:

run in class java.lang.Thread
