cross_trait_cors: Compute the cross-twin cross-trait correlations

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

Compute the cross-twin cross-trait correlations

Description

Compute the phenotypic correlations across twins and across traits, for MZ and DZ twins. Can be used for any data on groups.

Usage

get_cross_trait_cors(dat, zyg, vars, compact = FALSE)

Arguments

dat	the data.frame with the variables zyg and paste(vars, rep(1:2, each = nv))
zyg	the name of the zygosity variable (character string)
vars	the names of the variables to compute the descriptives for. If vars = c('X', 'Y', 'Z'), the function looks for c('X1', 'Y1', 'Z1', 'X2', 'Y2', 'Z2')
compact	return the MZ and DZ correlations in one table, MZ correlations on the upper triangle and DZ correlations on the lower triangle. Works only when the zygosity variable has exactly two levels
