When I try to save any plot as png, I get this error:
<simpleError in grDevices::png(..., res = dpi, units = "in"): impossible de d�marrer le p�riph�rique png()>
I have this error message when I try to update data in MariaDB / mySQL:
The meta-type of the column 'age inside the Anatella Graph (i.e.float) is incompatible with the meta-type of the column 'age' inside the database (i.e. non-number).
