BootCA-class: Partial bootstrap CA

Description

An S4 class to store partial bootstrap correspondance analysis results.

Usage

# S4 method for BootCA
[[(x, i)

# S4 method for BootCA [(x, i, j)

Arguments

x

A BootCA object from which to extract element(s).

i, j

Indices specifying elements to extract. i is a character string matching to the name of a slot. j can be missing or NULL, a numeric or character vector. Numeric values are coerced to integer as by as.integer (and hence truncated towards zero). Character vectors will be matched to the names of the object.

Methods (by generic)

  • [[: Extracts informations from a slot selected by subscript i.

  • [: Allows to select a slot thru j.

Slots

rows

A three columns data.frame giving the vertices coordinates of the samples convex hull and a identifier to link each row to a sample.

columns

A three columns data.frame giving the vertices coordinates of the variables convex hull and a identifier to link each row to a variable.

lengths

A two columns data.frame giving the convex hull maximum dimension length of each sample and a identifier to link each row to a sample.

cutoff

A length-one numeric vector giving the cutoff value for sample selection.

keep

A named numeric vector giving the subscript of the samples to be kept.
