SCImago Journal #68

Open DominiqueMakowski opened 6 years ago

DominiqueMakowski commented 6 years ago

Just discovered this nice package for extracting the SJR index of journals' prestige. It could potentially be a nice addition to the impact_factor related functions.

Specifically, as it includes the SJR index for different years, it would provide a unique opportunity to compute this index for each author's publication at their time of publication. Could be interesting for developing new authors' impact metrics.

Associating publications with journal impact factors is a nice feature to have, but a more immediate issue I think is to uniquely identify the journals, which Google Scholar does not do.

The sjr data available in the package seems outdated. Updated data is available here: https://www.scimagojr.com/journalrank.php?out=xls

Below is a modified version of get_journalrank() to download an updated version. (Please note that I'm using readr::read_csv2 due to problems with decimal separators in the scimago table and that readr has some parsing errors, that are due to missing quotes in the scimago data table). 

get_journalrank <- function (journals, max.distance = 0.05) {
  readr::read_csv2("https://www.scimagojr.com/journalrank.php?out=xls")-> myjournalrankings
  scholar:::get_journal_stats(journals, max.distance, myjournalrankings, col= "Title")
}
