When TRUE, a modified version of x is returned invisibly Should x be modified in place? This argument is only It is a potentially expensive operation so you must opt into it. This allows you to join tables across srcs, but If x and y are not from the same data source,Īnd copy is TRUE, then y will be copied into the "ignore" will ignore rows in y with keys that conflict with keys in "error", the default, will error if there are any keys in y that With keys in x be handled?
