Mechanism to check for duplicate citations while adding citations in the preview releases

[drsharma]

Rsudio Version 1.4.869 preview: IN Visual markdown mode I notice when we add citations using a search engine say for PMID or DOI and let the program add the entry to the BibTeX database there is no mechanism to prevent duplicate citations being added. I wonder if there are any plans to add a mechanism to prevent this from happening?
I love the direction the IDE is going though.

Best regards

Thanks for the suggestion - you're right in the case of PMID or DOI we could be deduplicating these and re-using the citekey and entry that already exist in the bibliography. I'm going to take a closer look at this - thanks again!

Another suggestion: I notice if you use visual markdown and add references and then go back to add another reference in the same place it is buggy: The reference is not "added" as a cluster but as an additional reference. You can try to correct that with removing the around the new reference added but then the references are not recognized at all! Switching the visual markdown off shows the new added reference in plain markdown has “@....” once the “\” is removed from before @ and the additional deleted the reference cluster is recognized correctly.

I can send screenshots if needed.

Very good direction the ide is taking

This is what it looks like after adding a citation

Here is a cluster of citations[@Vrillon2020[@Robson2020; @Zhuang2020; @Farfour2020]]

see the double square bracket

and the output in word you see the three new citations are not picked up in the text although they appear in the references

Here is a cluster of citations^1

Thanks for reporting this! I've logged an issue to track this here

Insert Citations in Existing Citations Fails

I will look into it, but in the meantime, as you probably figured out, your best bet is to delete and re-insert citations into a cluster rather than trying to add an entry to an existing citation.
