Error in ind[i] <- ind[i - 1] : replacement has length zero #110

Closed IsidroJ closed 4 years ago

IsidroJ commented 4 years ago

When I am running the code (bibliometrix 3.0.0), an error occurred:

DatosSCOPUS <- "C:/Users/IJGH/Desktop/BD_SCOPUS_50.bib"

S <- convert2df(file = DatosSCOPUS, dbsource = "scopus", format = "bibtex")

Error in ind[i] <- ind[i - 1] : replacement has length zero

Can you help me please.

The error occurs because I'm your file some mandatory metadata are missing.

Try to update bibliometrix from GitHub.

I added an user warning but the function should complete the conversion process.

Dear Dr. Massimo,

After updating bibliometrix from GitHub the problem could be solved. Thank you very much for your help. I have finished writing my paper and am in the process of submitting it to a journal.

I am now searching for information to learn how to get the maximum likelihood estimators with RStudio.

Best regards,
