How to set an attribute to a vector in rpy2
Question: How to add attributes to vectors in python with rpy2. As an example how can I
reproduce this R code:

    
    
    library(evir)
    pot<-c(2.0,3.2,4,5,6,7)
    ts<-c(1,6,7,19,20,30)
    attr(pot,"times")<-ts
    output<-decluster(pot,run=2)
    

I can't find any help after searching several hours on the net. I guess
Laurent has the answer ;-)


Answer: Use the attribute `slots`. What is described about it in the doc for S4
objects applies to attributes
(<http://rpy2.readthedocs.org/en/version_2.7.x/notebooks/s4class.html>).

Here it should work with:

    
    
    from rpy2.robjects.vectors import FloatVector, IntVector
    pot = FloatVector((2.0, 3.2, 4, 5, 6, 7))
    ts = IntVector((1,6,7,19,20,30))
    pot.slots['times'] = ts
    

For rpy2 < 2.7, you should use do_slot_assign :

    
    
    pot.do_slot_assign("times",ts)
