我试图通过构建一个顶点列表数据框，通过 RISmed 包从 PubMed 获取文章来构建一个 R igraph 图，如下所示：

Name              Count
Cardone L         22
...               ...
Sassone-Corsi P   6
...               ...

和相应的（无向）边列表

V1        V2              NumberOfCoAuthorships
Cardone L Sassone-Corsi P 4

这是我正在获取的数据：

#install.packages("RISmed")
library(RISmed)
limit = 100
query = "Cardone L[AUTH]"
# build the Eutils object
search_query <- EUtilsSummary(query, type="esearch",db = "pubmed",mindate=1980, maxdate=2016, retmax=limit)
# now let's fetch authors
auths<-Author(EUtilsGet(search_query))
# to extract all the names in the LastName Initials format
Authors<-sapply(auths, function(x)paste(x$LastName,x$Initials))

但我真的没有考虑如何从作者字符串列表中为未来的 igraph 图形对象构建边和顶点数据帧

> head(Authors,3)
