indexSelfConstruction: Self construction profile

In markheckmann/OpenRepGrid: Tools to Analyze Repertory Grid Data

Self construction profile

Description

TBD

Usage

indexSelfConstruction(
  x,
  self,
  ideal,
  others = c(-self, -ideal),
  method = "euclidean",
  p = 2,
  normalize = TRUE,
  round = FALSE
)

Arguments

x	A repgrid object.
self	Numeric. Index of self element.
ideal	Numeric. Index of ideal element.
others	Numeric. Index(es) of self related "other" elements (e.g. father, friend).
method	The distance or correlation measure: Distances: euclidean, manhattan, maximum, canberra, binary, minkowski Correlations: pearson, kendall, spearman
p	The power of the Minkowski distance, in case minkowski is used as argument for method, otherwise it is ignored.
normalize	Normalize values?
round	Round average rating scores for 'others' to closest integer?

Value

List object of class indexSelfConstruction, containing the results from the calculations:

• grid: Reduced grid with self, ideal and others

• method_type: method type (correlation or distance)

• method: correlation or distance method used

• self_element: name of the self element

• ideal_element: name of the ideal element

• other_elements: name(s) of other elements

• self_ideal: measure between self and ideal

• self_others: measure between self and others

• ideal_others: measure betwen ideal and others

Examples

# using distance measures
indexSelfConstruction(boeker, 1, 2, c(3:11), method = "euclidean")
indexSelfConstruction(boeker, 1, 2, c(3:11), method = "manhattan")
indexSelfConstruction(boeker, 1, 2, c(3:11), method = "minkowski", p = 3)

# using correlation measures
indexSelfConstruction(boeker, 1, 2, c(3:11), method = "pearson")
indexSelfConstruction(boeker, 1, 2, c(3:11), method = "spearman")

# using not-normalized distances
indexSelfConstruction(boeker, 1, 2, c(3:11), method = "euclidean", normalize = FALSE)

# printing the results (biplot only works with)
cp <- indexSelfConstruction(boeker, 1, 2, c(3:11))
cp$grid  # grid with self, ideal and others
biplot2d(cp$grid, center = 4)  # midopoint centering
