A C++ purpose is analogous to an R function: you move a list of inputs to the perform, some code is operate, one object is returned. On the other hand there are many key discrepancies.
If a method with the right title and arguments will not be observed at compile time, an mistake is thrown. The main difference with "standard" Groovy is illustrated in the following example:
Braces are essential about Each and every block’s overall body. attempt 'moo'.toLong() // this will create an exception assert false // asserting this place should really under no circumstances be reached catch ( e ) assert e in NumberFormatException
