jython.exec

Executes python code via the Jython interpreter

  jython.exec( rJython, python.code )

`rJython`	rJython interpreter as instantiated by function `rJython`
`python.code`	a character vector containing python code, typically containing a single line with indentation and EOL characters as required by Python syntax

This function runs Python code. It needs to be provided by the caller in a character vector.

The vector may consists of a single string with EOL and indentation characters embedded.

Alternatively, it can be a character vector, each entry containing one or more lines of python code.

None. If the code produces some output, it is up to the caller to go and fetch if from Jython.


rJython <- rJython()

a <- 1:4
b <- 5:8
jython.exec( rJython, c( "def concat(a,b):", "\treturn a+b" ) )
jython.call( rJython, "concat", a, b)
