custom.subsets {dispRity}R Documentation

Separating data into custom subsets.

Description

Splits the data into a customized subsets list.

Usage

custom.subsets(data, group, tree = NULL)

Arguments

data

A matrix or a list of matrices.

group

Either a list of row numbers or names to be used as different groups, a data.frame with the same k elements as in data as rownames or a factor vector. If group is a phylo object matching data, groups are automatically generated as clades (and the tree is attached to the resulting dispRity object).

tree

NULL (default) or an optional phylo or multiPhylo object to be attached to the data.

Details

Note that every element from the input data can be assigned to multiple groups!

Examples

## Generating a dummy ordinated matrix
ordinated_matrix <- matrix(data = rnorm(90), nrow = 10)

## Splitting the ordinated matrix into two groups using row numbers
custom.subsets(ordinated_matrix, list(c(1:4), c(5:10)))

## Splitting the ordinated matrix into three groups using row names
ordinated_matrix <- matrix(data = rnorm(90), nrow = 10,
     dimnames = list(letters[1:10]))
custom.subsets(ordinated_matrix,
     list("A" = c("a", "b", "c", "d"), "B" = c("e", "f", "g", "h", "i", "j"),
          "C" = c("a", "c", "d", "f", "h")))

## Splitting the ordinated matrix into four groups using a dataframe
groups <- as.data.frame(matrix(data = c(rep(1,5), rep(2,5), rep(c(1,2), 5)),
     nrow = 10, ncol = 2, dimnames = list(letters[1:10], c("g1", "g2"))))
custom.subsets(ordinated_matrix, groups)

## Splitting a matrix by clade
data(BeckLee_mat50)
data(BeckLee_tree)
custom.subsets(BeckLee_mat50, group = BeckLee_tree)
