process_twin_data: Process twin data into MxData objects

In IvanVoronin/TwinAnalysis: This is a package to simplify structural equation modeling - and particularly, twin analysis - in R.

Process twin data into MxData objects

Description

Process twin data into MxData objects to add to MxModel. The function accepts raw data and covariance matrices.

Usage

process_twin_data(data, selvars, data_type = "raw", zyg = character(0))

Arguments

data	data.frame or list
data_type	'raw', 'cov' or 'cor', as required by type parameter of mxData
zyg	factor used to split the data frame when data_type = 'raw'

Details

When data_type = 'raw' (default), the data must be a data frame or matrix with raw data that will be split upon factor zyg and passed to mxData. When data_type = 'cov' or 'cor', the data must be a (named) list of arguments passed to mxData, including observed - covariation or correlation matrix, numObs - number of observations, means - vector of means. The type argument is not required as it is added from data_type. Refer to ?mxData for details on mxData arguments.

Value

A list of MxData objects
