I use cast() from the reshape package quite frequently. Almost every time, this warning pops up:
Aggregation requires fun.aggregate: length used as default
I’ve tried to set options( warn =-1), to no avail. How does one suppress these warnings?
You could manually specify fun.aggregate to be length.
