Single indicators

[HanZhang-psych]

Hello!

I wonder if there is a way to selectively show a single indicator in the structural part of the model while hiding the measurement part. Here is an example:

library(lavaan)
library(semPlot)
model <- "
  lv1 =~ mpg + cyl + wt
  lv2 =~ am + vs + gear
  drat ~ lv1
  lv2 ~ drat

"
fit <- sem(model, data = mtcars)
semPaths(fit)

I'd like to hide the manifest variables but keep drat in the plot. Using structural=T would remove drat from the plot.

Thank you! Han

Hi Han,

This is not possible at the moment, but you could represent DRT with a latent variable in the lavaan model for an equivalent setup.

Best, Sacha
