Retrieve citations of a journal paper using R
问题 Using R, I want to obtain the list of articles referencing to a scientific journal paper. The only information I have is the title of the article, e.g. "Protein measurement with the folin phenol reagent". Is anyone able to help me by producing a replicable example that I can use? Here is what I tried so far. The R package fulltext seems to be useful, because it allows to retrieve a list of IDs linked to an article. For instance, I can get the article's DOI: library(fulltext) res1 <- ft_search
