Hi, I have a list of 40 data.frames.
I would like to identify duplicated entries in the whole list, not only in one specific data.frame, but in all 40. Here is my list: > myList [[1]] X NAME MEM.SHIP 1 FBgn0000008 FBgn0000008 0.9304502 2 FBgn0000014 FBgn0000014 1.0000000 3 FBgn0000028 FBgn0000028 1.0000000 4 FBgn0000109 FBgn0000109 1.0000000 5 FBgn0000114 FBgn0000114 0.4839886 6 FBgn0000120 FBgn0000120 1.0000000 [[2]] X NAME MEM.SHIP 1 FBgn0000251 FBgn0000251 0.3138650 2 FBgn0001168 FBgn0001168 0.8995011 3 FBgn0001941 FBgn0001941 0.7485548 4 FBgn0003053 FBgn0000028 0.4426997 5 FBgn0003159 FBgn0003159 0.4843226 6 FBgn0000120 FBgn0003162 0.6556290 I would like to know whether there are duplicated entries in the first and/or second column of all. In this list I have two duplications one is FBgn0000120 in both lines Nr. 6 and the second is FBgn0000028 in line 3 and line 4 in df1 and df2 respectively. Is there a way to do it. With unique I don't get any results. and I cannot convert the list into a data.frame, as the number of items in each df is different.
