Problems with new Lavaan version 06.18

[Marcel Elipe Miravet]

I was carrying out a growth model; this was the syntax (in fact, the syntax is not important):

growth(shinozaki, data = Kanfer, estimator = "MLR", mimic='mplus',
                    auto.fix.first = F, meanstructure = TRUE, int.ov.free = FALSE,
                    int.lv.free = TRUE,auto.fix.first = TRUE, auto.fix.single = TRUE,
                    auto.var = TRUE, auto.cov.lv.x = TRUE, auto.efa = TRUE,
                    auto.th = TRUE, auto.delta = TRUE,  auto.cov.y = TRUE, start = "Mplus")

However, with the new version (06.18), there is a message error:

"Error: lavaan->lav_options_set(): start option must be 'default', 'simple', 'est' or a parametertable"

I think the problem is the "start = "Mplus", because in the version 06.17 it didn't appear.

Does anyone else have this problem?

Short answer: remove the start = "Mplus" argument, or replace it by
start = "default" (which is very similar, but not identical to what
Mplus does).

Longer answer: this is a documentation issue. The start= argument has
evolved over the years (and a variant of 'Mplus' became the default).
But the documentation was not updated. Will do that soon.
