aphylo-index: Indexing aphylo objects

Description

Indexing aphylo objects

Usage

# S3 method for aphylo
[(x, i, j, drop = FALSE)
# S3 method for aphylo
[(x, i, j) <- value

Value

• When indexing with i: A data frame with the annotations of the selected genes.

• When only indexing with j (drop = FALSE): An aphylo object with the selected sets of annotations.

• When only indexing with j (drop = TRUE): A data.frame with the selected annotations.

• When indexing on both i and j: A data.frame with the selected genes and annotations.

Arguments

x

An object of class aphylo.

i, j

Integer vector. Indices of genes or functions.

drop

Logical scalar. When TRUE, the function returns a matrix of annotations. Otherwise an object of class aphylo.

value

Integer vector. Replacing values, can be either c(0, 1, 9, NA).

Details

The subsetting method allows selecting one or more annotations from the aphylo object. Whenever i is specified, then aphylo returns the corresponding annotations.

Examples

set.seed(12312)
atree <- raphylo(50, P = 4)
atree[1:10,]
atree[,2:3]
atree[, 2:3, drop = TRUE]
atree[1:10, 2:3]
