triad.test: triad.test

In alastair-JL/AnthroTools: Some custom tools for anthropology

triad.test

Description

You get a similarity matrix of triad test data. You'll probably need to convert it to a dissimilarity matrix to plot it. See examples.

Usage

triad.test(data)

Arguments

data

This is triad data. It needs to consist of: (1) an identifying number for each triad (NUM), (2-4) the specific items of the triad (item1, item2, item3), and (5-n) participants' selection of the most distinct item of the triad, the triad.test() function will create an item-by-item similarity matrix (PART1, PART2, ... PARTn).

Value

The output here is the similarity matrix of the triad data.

Note

Pay close attention to the nature of the input data. The function will only work when data are in this particular shape and format. See the example below.

Examples

  data(RVSfaculty)
  d.diff <- triad.test(RVSfaculty) # similarity matrix
  d.sim <- as.dist(1 - d.diff) # dissimilarity matrix
  plot(hclust(d.sim), main = NULL)
