Examples

m <- sf_model(
  "cb1", "Quality drives intention", type = "cb_sem",
  constructs = list(
    sf_construct("sq", "Service Quality", items = c("sq_1", "sq_2", "sq_3")),
    sf_construct("sat", "Satisfaction", items = c("sat_1", "sat_2")),
    sf_construct("bi", "Behavioural Intention", items = c("bi_1", "bi_2"))
  ),
  paths = list(sf_path("sq", "sat"), sf_path("sat", "bi")),
  indirect = list(sf_indirect("sq", through = "sat", to = "bi"))
)
m$type
#> [1] "cb_sem"
m$engine
#> [1] "lavaan"
