fast_sca: Simple Correspondence Analysis

Description

A fast procedure for computing simple correspondence analysis.

Usage

fast_sca(dat)

Arguments

dat

Input data: can be a table or a data frame (but the data frame must have only two columns).

Value

• A list with components:
• val
  The eigenvalues or principal inertias, indicating how much each latent axis explains.
• pos1
  The coordinates of the first set of levels (viz. the row levels of a frequency table).
• pos2
  The coordinates of the second set of levels (viz. the column levels of a frequency table).

Examples

SndT_Fra <- read.table(system.file("extdata", "SndT_Fra.txt", package = "svs"),
   header = TRUE, sep = "\t", quote = "\"", encoding = "UTF-8")
sca.SndT_Fra <- fast_sca(SndT_Fra)
sca.SndT_Fra
