You have mixed slashes in this sentence. Therefore I wonder if your quarto installation is correct.
Do you get any errors when enter the following statement in the terminal panel:

$ quarto.cmd check

?

Did you have any luck with other quarto files or is it just an empty r chunk that fails?

Dear Han

Thank you for your reply.

The problem has been solved by quarto version 1.2 https://quarto.org/docs/download/prerelease.html\

quarto.cmd check

results in everything "OK".

But quarto 1.2 works now for me.

Many Thanks.
