This code use to work, but now errors, any idea why?
library(bayestestR)
library(blavaan)
data("PoliticalDemocracy", package = "lavaan")
model <- "
# latent variable definitions
dem60 =~ y1 + a*y2
dem65 =~ y5 + a*y6
# regressions
dem65 ~ dem60
# residual correlations
y1 ~~ y5
"
model2 <- "
# latent variable definitions
dem60 =~ y1 + a*y2
dem65 =~ y5 + a*y6
# regressions
dem65 ~ 0*dem60
# residual correlations
y1 ~~ 0*y5
"
suppressWarnings(capture.output({
bfit <- blavaan::bsem(model,
data = PoliticalDemocracy,
n.chains = 1, burnin = 50, sample = 100
)
bfit2 <- blavaan::bsem(model2,
data = PoliticalDemocracy,
n.chains = 1, burnin = 50, sample = 100
)
}))
blavaan::blavCompare(bfit, bfit2)
#> Error in apply(diffs, 2, sum) : dim(X) must have a positive length

Thanks for the report! This was recently discussed at the thread below, and it should be fixed on github. A workaround for the current CRAN version is to add meanstructure = TRUE
to bsem()
.
