Create DIGRAM Object

Description

Create a digram.object.

Usage

digram.object(project=NULL,data=data.frame(),variables=colnames(data),filter.conditions=data.frame(variable.number=numeric(0),min=numeric(0),max=numeric(0)),recursive.structure=c(),comments="")

Arguments

project	The name of the DIGRAM project
data	The data.frame or matrix with the data
variables	A vector of column names or numbers from the dataset to include in the recoded dataset (the order matters in the recoded data) or a list of variables each element in the form list(variable.name="",variable.label="",ncat=0,category.names=c(),variable.type=c("nominal","ordinal"),minimum=0,maximum=1,cutpoints=c())
filter.conditions	A data.frame with three columns: variable.number, max, and min. Only cases, for which all values of filter variables belong to the intervals defined by the corresponding minimum and maximum values (both included), will be used in the analysis.
recursive.structure	A vector of cutpoints to define the recursive blocks
comments	A string

Value

Returns a digram.object
