xmu_twin_get_var_names: Not for user: pull variable names from a twin model

In tbates/umx: Structural Equation Modeling and Twin Modeling in R

Not for user: pull variable names from a twin model

Description

Barely useful, but justified perhaps by centralizing trimming the "_T1" off, and returning just twin 1.

Usage

xmu_twin_get_var_names(
  model,
  source = c("expCovMZ", "observed"),
  trim = TRUE,
  twinOneOnly = TRUE
)

Arguments

model	A model to get the variables from
source	Whether to access the dimnames of the "expCovMZ" or the names of the "observed" data (will include covariates)
trim	Whether to trim the suffix (TRUE)
twinOneOnly	Whether to return on the names for twin 1 (i.e., unique names)

Value

• variable names from twin model
