These are extraction and replacement operators for lists of trees
stored in the class "multiPhylo"
.

## S3 replacement method for class 'multiPhylo'
x$i <- value
x , value |
an object of class |
i |
index(ices) of the tree(s) to select from a list; this may be a vector of integers, logicals, or names. |
name |
a character string specifying the tree to be extracted. |
The subsetting operator [
keeps the class correctly
("multiPhylo"
).
The replacement operators check the labels of value
if x
has a single vector of tip labels for all trees (see examples).
An object of class "phylo"
([[
, $
) or of class
"multiPhylo"
([
and the replacement operators).
