If you’re using one of the product indicator approaches, you might
want to use some lavaan functions on top of the estimated lavaan-object.
To do so you can extract the lavaan-object using the
`extract_lavaan()`

function.

```
library(lavaan)
#> This is lavaan 0.6-19
#> lavaan is FREE software! Please report any bugs.
m1 <- '
# Outer Model
X =~ x1 + x2 + x3
Y =~ y1 + y2 + y3
Z =~ z1 + z2 + z3
# Inner model
Y ~ X + Z + X:Z
'
est <- modsem(m1, oneInt)
lav_object <- extract_lavaan(est)
bootstrap <- bootstrapLavaan(lav_object, R = 500)
```
