Encountered lav_object_summary Error while running CFA

Question

This is my code:

DATA <- read_excel("FINAL DATA.xlsx")
CFA1 <-'
          F1 =~ Q1 + Q2 + Q3 + Q4
          F2 =~ Q5 + Q6 + Q7 + Q8
          F3 =~ Q9 + Q10 + Q11 + Q12
          F4 =~ Q13 + Q14 + Q15 + Q16
          M =~ 1*F1 + 1*F2 + 1*F3 + 1*F4
          F1 ~~ F2
          F1 ~~ F3
          F1 ~~ F4
          F2 ~~ F3
          F2 ~~ F4
          F3 ~~ F4
          '
f1 <- sem(CFA1, data= PHD_FINAL_DATA, std.lv=TRUE, ordered=c("Q1","Q2","Q3","Q4",
                                                             "Q5","Q6","Q7","Q8",
                                                             "Q9","Q10","Q11","Q12",
                                                             "Q13","Q14","Q15","Q16"))
summary(f1, rsquare= TRUE, fit.measures=TRUE)

However, I'm getting this error code when I run the summary line:

Error in lav_object_summary(object = object, header = header, fit.measures = fit.measures, : unused argument (std.nox = std.nox)

Answer 1

The reprex below works with the latest version of lavaan. Could you try it and see if it works for you? Otherwise, you might just need to update lavaan to the latest version.

library(lavaan)
packageVersion("lavaan")
#> [1] '0.6.18'
HS.model <- ' visual  =~ x1 + x2 + x3
              textual =~ x4 + x5 + x6
              speed   =~ x7 + x8 + x9 '
fit <- sem(HS.model, data = HolzingerSwineford1939)
out <- summary(fit, rsquare= TRUE, fit.measures = TRUE)

To resolve your error, please install the latest version of blavaan. The source of the issue is a bit complicated but you can refer to the GitHub issue opened on about this.
