bibliometrix problem with the Thematic evolution map
Hi everyone,
I have run biblioshiny and uploaded a bibliometric database (merging Scopus and WoS databases). Still, when I chose the thematic evolution map, It jumped a mistake: duplicate 'row. names' are not allowed.
It does not generate the thematic evolution map using the author's keywords by periods.
Thank you for any help you can provide.
Note: I've attached the .xls document of the merged database.
The error indicates that there are duplicate rows in your excel collection. Bibliometrix uses the column with the tag "SR" as document ID and when this column contains duplicates then it returns an error.
Checking your file, there are two documents with an SR value of "ADAMS J, 1991, NATURE" (rows 2854 and 3235). If the two rows refer to the same document then one should be deleted otherwise you need to assign two different SR values to the two rows.
Thank you so much; I have reviewed the SR value and deleted the duplicates, but bibliometrix maintains the same problem.
