Hello David,
Simply:
class(y) <- "multiPhylo"
Best,

Subject: [R-sig-phylo] Converting a List of Trees into a multiPhylo Object
Hello all,
I have a lapply() function which is outputting phylo objects (the input is a
list of complicated tables, each of which corresponds to a resulting tree,
long story).
The following is NOT what I'm doing, but gives you an idea of what the
result from lapply() looks like.
require(ape)
x<-list(5,10)
y<-lapply(x,rtree)
Unfortunately, this makes a list of trees (as can be shown with class(y) ),
not a multiPhylo object. Hrm.
One possibility, of course, is to use rmtree to make a placeholder and than
fill it with the original trees:
z<-rmtree(length(y),2)
for(i in 1:length(y)){z[[i]]<-y[[i]]}
...but that's kind of inelegant. I feel like there must be a simpler
solution.Is there any simple way to convert a list of trees into a
multiPhylo object?
-Dave
