Propagate for FLPar fails without warning if iters are present

[colinpmillar]

Propagate behaviour for FLQuants is that, if is the object has n iters and you ask for n iters you get the object back, which is quite nice :)

flq <- propagate(FLQuant(1), 2)
identical(flq, propagate(flq, 2))
##  [1] TRUE

But for FLPar object we get an error

flp <- propagate(FLPar(1), 2)
propagate(flp, 2)
##  Error in do.call("[<-", c(list(x = x@.Data), dx, list(value = value))) : 
##    number of items to replace is not a multiple of replacement length

Would it be possible to have the same behaviour for FLPar objects?

Sure, now added in commit 2520733
