Problems with author's countries?

[yangxg]

Hello Massimo:

I really appreciate this great tool!

Following the example you provided, the AU_CO and AU1_CO produced by pmApi2df(D) function are NA. I inspect the source code and found that you are design it purposely. I don't know if it was not complete yet, but it is country information important for the subsequant bibliometric analysis, in my eyes.

Could you take a look at it? Thanks

Please, upload your full script

Sorry, and please take a look at the script

library(pubmedR)
library(dplyr)

query <- "bibliometric*[Title/Abstract] AND english[LA] AND Journal Article[PT] AND 2019:2020[DP]"

api_key <- NULL

D <- pmApiRequest(query = query, limit = 100, api_key = api_key)

M <- pmApi2df(D)

M[c('AU_CO','AU1_CO')] %>% head

  AU_CO AU1_CO
1    NA     NA
2    NA     NA
3    NA     NA
4    NA     NA
5    NA     NA
6    NA     NA

I hope that the author country information could be acquired, so that I could replicate the attractive examples provided in the bibliometrix manual. Thanks!
