Merged data problem #586
Description
Dear @massimoaria
I am currently writing a bibliometric analysis on a topic with very limited literature, so I have to use five different databases. I noticed that when importing each database separately, Scopus, OpenAlex, and Dimensions can successfully generate the countries’ collaboration world map. However, when I import data from Lens.org (63 records), it shows ‘[object Object]’, and with PubMed (4 records), it shows ‘replacement has 1 row, data has 0’. Finally, when I merge all five databases and try to run the analysis, I also receive the error ‘replacement has 1 row, data has 0’. Please help me with this issue.
Thank you.
