c.phylo: Building Lists of Trees

Description

These functions help to build lists of trees of class "multiPhylo".

Usage

## S3 method for class 'phylo':
c(..., recursive = FALSE)
## S3 method for class 'multiPhylo':
c(..., recursive = FALSE)
.compressTipLabel(x)
.uncompressTipLabel(x)

Arguments

Value

An object of class "multiPhylo".

Details

These c methods do not check all the arguments, so it is the user's responsibility to make sure that only objects of the same class (either "phylo" or "multiPhylo") are used.

.compressTipLabel transforms an object of class "multiPhylo" by checking that all trees have the same tip labels and renumbering the tips in the edge matrix so that the tip numbers are also the same taking the first tree as the reference (duplicated labels are not allowed). The returned object has a unique vector of tip labels (attr(x, "TipLabel")).

.uncompressTipLabel does the reverse operation.

Examples

Run this code
x <- c(rtree(4), rtree(2))
x
y <- c(rtree(4), rtree(4))
z <- c(x, y)
z
print(z, TRUE)
try(.compressTipLabel(x)) # error
a <- .compressTipLabel(y)
.uncompressTipLabel(a) # back to y
## eventually compare str(a) and str(y)
