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

Where all data are missing for a twin, add default values for definition variables, allowing the row to be kept

Description

Replaces NAs in definition slots with the mean for that variable ONLY where all data are missing for that twin.

Usage

xmu_PadAndPruneForDefVars(
  df,
  varNames,
  defNames,
  suffixes,
  highDefValue = 99,
  rm = c("drop_missing_def", "pad_with_mean")
)

Arguments

df	The dataframe to process
varNames	list of names of the variables being analysed
defNames	list of covariates
suffixes	that map names on columns in df (i.e., c("T1", "T2"))
highDefValue	What to replace missing definition variables (covariates) with. Default = 99
rm	= how to handle missing values in the varNames. Default is "drop_missing_def", "pad_with_mean")

Value

• dataframe
