Reinforcing measurement scale for ordinal data

Description

Reinforcing measurement scale for ordinal data (ordinal to metric scale)

Usage

ordinalToMetric(data,scaleType="o",patternCoordinates)

Arguments

data	matrix or dataset
scaleType	"o" - variables measured on ordinal scale, "m" - variables measured on metric scale, "o/m" - vector with mixed variables - e.g. c("o","m","m","o","o","m")
patternCoordinates	vector containing pattern coordinates c(...) given by the reaseracher for data (for metric variables - NA, for ordinal variables - one of the categories for each ordinal variable (e.g. maximum category))

Details

See file ../doc/ordinalToMetric_details.pdf for further details

Value

pdata	raw (primary) data matrix
tdata	data matrix after transformation of ordinal variables into metric variables
cpattern	vector containing pattern coordinates
