partialInvariance "Error in out[free != 0] <- est[free[free != 0]]: replacement has length zero"

[SarBearSchwartz]

I have been using this package a great deal recently. Today I had to update my software to get my Rmd file to knit to pdf. Once I updated R to version 4.2.0 (64-bit Windows 10), the function "partialInvariance" started returning: "Error in out[free != 0] <- est[free[free != 0]]: replacement has length zero". This error is returned when running the code below (from the function "help" documentation).

library(lavaan)

conf <- "
f1 =~ NA*x1 + x2 + x3
f2 =~ NA*x4 + x5 + x6
f1 ~~ c(1, 1)*f1
f2 ~~ c(1, 1)*f2
"

weak <- "
f1 =~ NA*x1 + x2 + x3
f2 =~ NA*x4 + x5 + x6
f1 ~~ c(1, NA)*f1
f2 ~~ c(1, NA)*f2
"

configural <- cfa(conf, data = HolzingerSwineford1939, std.lv = TRUE, group="school")
weak <- cfa(weak, data = HolzingerSwineford1939, group="school", group.equal="loadings")
models <- list(fit.configural = configural, fit.loadings = weak)
partialInvariance(models, "metric")

I added 3 backticks before and after your code, so that the code appears as desired (i.e., so the Markdown interpreter does not treat text between asterisks as italics).

I have no problem running this syntax in R 4.2.0 using semTools 0.5-6. Have you (re)installed semTools after re-installing R? That could help.

[SarBearSchwartz]

Thank you for responding. I also use the backticks to run in Rmd. Additionally, I copy-pasted the code into the console and received the same error. In the help page for partialInvariance() (viewed inR Studio), clicking the "Run examples" link at the bottom yields the same error, too.

I was using the CRAN version, but I confirmed that development version 0.5-6.904 threw that error on my Mac, too. Couldn't exactly figure out the cause, but I at least narrowed down the origin to a change I had no problem reversing. Development version 0.5-6.905 no longer throws that error.

[SarBearSchwartz]

Thank you! I installed the latest developmental version and no longer receive an error message.
