c.phylo {ape} | R Documentation

## 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

`...` | one or several objects of class `"phylo"` or `"multiPhylo"`.
`recursive` | for compatibily with the generic (do not change).
`x` | an object of class `"phylo"` or `"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.

### Value

An object of class `"multiPhylo"`.

### Examples

    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)
