Difficuult, really difficult. We do not have data, your OS, R version,
error message (if there is any). It reminds me like if your car stopped
and you asked by phone somebody a question #It doesn't work?!?!?! What

BTW it works as expected

[1] TRUE

And I have carichi.annui.lav file in my working directory.
Therefore you have to check yourself or at least provide some clues.
