Examples

## A multiple regression model
model <- "y ~ x1 + x2
          x1 ~~ 1*x1
          x2 ~~ 1*x2
          x1 ~~ x2"

## RAM specification
RAM <- lavaan2RAM(model, obs.variables=c("y", "x1", "x2"))

## Create a moderator matrix on A with "meanAge as the moderator.
A1 <-  create.modMatrix(RAM=RAM, output="A", mod="meanAge")
A1

## Create a moderator matrix on S with "meanAge as the moderator.
S1 <-  create.modMatrix(RAM=RAM, output="S", mod="meanAge")
S1
