rbind error names do not match previous names

Question

As part of a larger problem  adding a  makeUniqueIDs argument to rbind SpatialPolygonsDataFrame for situations when the polygon IDs are identical   I m running into this weird message from rbind    gt  do call  rbind  xd small  Error in match names clabs  names xi        names do not match previous names    xd small dput output   The only other info I could find on this was this question  which leads me to believe that rbind was at the root of the problem there also   I can just write my own rbind-like function of course  but presumably this match names check occurs for a reason  and I m curious what it is

The names of the first dataframe do not match the names of the second one  Just as the error message says    gt  identical names xd small  1     names xd small  2       1  FALSE   If you do not care about the names of the 3rd or 4th columns of the second df  you can coerce them to be the same    gt  names xd small  1     lt - names xd small  2      gt  identical names xd small  1     names xd small  2       1  TRUE   Then things should proceed happily

check all the variables names in both of the combined files  Name of variables of both files to be combines should be exact same or else it will produce the above mentioned errors  I was facing the same problem as well  and after making all names same in both the file  rbind works accurately   Thanks

rbind   needs the two object names to be the same  For example  the first object names  ID Age  the next object names  ID  Gender if you want to use rbind    it will print out      names do not match previous names
