Question

I’m trying to run a script, but the following error is appearing: udunits system database read from C:/Users/André/Documents/R/win-library/4.1/udunits2/share/udunits/udunits2.xml summarise() has grouped output by 'UF'. You can override using the .groups argument. Quitting from Lines 42-129 (program.Rmd) Error: by must be supplied when x and y have no common variables. i use by = Character()` to perform a cross-Join.

Backtrace: x

Does anyone know what it can be?
