Consider the following code. It seems like the errors that occur when y only has a key column is a bug. Yes?
DT<-data.table(a=rep(1:2,each=3),b=1:6,key="a") y<-J(a=c(0,1),bb=c(10,11),key="a") # y, with key column and one more column merge(y,DT) # fine merge(y,DT,all=TRUE) # fine y<-J(a=c(0,1),key="a") # y with only a key column merge(y,DT) # fine merge(y,DT,all=TRUE) # error merge(DT,y,all=TRUE) # a different error
