Lavaan error message

[Andries Noeth]

Hi Support group,

I'm using Jasp to build a SEM and found the following error message. 

"Some latent variable names collide with observed variable names: SAT_Dr SAT_Nu, SAT_ovall.

This is the syntax code is used:

  # latent variables

SAT_Dr =~ DR_1 + DR_2 + DR_3 + DR_4

SAT_Nu =~ Nu_1 + Nu_2 + Nu_3 + Nu_4

SAT_Ovall =~ Env_1 + Env_2 + Env_3 + Env_4 + Med_1 + Med_2 + Med_3 + Med_4 + Dis_1 + Dis_2

# regressions

REC ~ SAT_Dr + SAT_Nu + SAT_Ovall

Choose ~ SAT_Dr + SAT_Nu + SAT_Ovall

Any advice will be greatly appreciated

Maybe it is because the dataset already have columns named SAT_Dr, SAT_Nu, and SAT_Ovall?

I can produce a similar error by creating the columns with names equal to the factors:

``` r
library(lavaan)
#> This is lavaan 0.6-17
#> lavaan is FREE software! Please report any bugs.
dat <- HolzingerSwineford1939
dat$visual <- rowSums(dat[, c("x1", "x2", "x3")])
dat$textual <- rowSums(dat[, c("x4", "x5", "x6")])
HS.model <- ' visual  =~ x1 + x2 + x3
              textual =~ x4 + x5 + x6
              speed   =~ x7 + x8 + x9 '
fit <- cfa(HS.model, data = dat)
#> Error in lavaan::lavaan(model = HS.model, data = dat, int.ov.free = TRUE, : lavaan ERROR: some latent variable names collide with observed
#>      variable names: visual textual
```

Hi Shu Fai,

Thanks for the quick response, really appreciate it! The data file indeed has columns with those variable names. Excuse my ignorance, I'm a new Jasp user. What is the solution?

How about using names that do not exist in the dataset for the latent factors? E.g., SATDr, SATNu, and SATOvall?

P.S.: I rarely use JASP. My suggestion is based on my knowledge about lavaan, which I guess is used by JASP to do SEM.
