The error says: "Field CR_AU is not a column name of input data frame"
When you perform a co-citation analysis of authors, the biblioNetwork function needs to analyze a field "CR_AU" containing the list of authors extracted from references (CR). This column field is not standard so it has to be extracted from Cited References (CR) using the function metaTagExtraction: scientometrics <- metaTagExtraction(scientometrics, Field="CR_AU")
and then you can perform an author co-citation analysis NetMatrix <- biblioNetwork(scientometrics, analysis = "co-citation", network = "authors", sep = ";")
net <- networkPlot(NetMatrix, n = 30, type = "kamada", Title = "Co-Citation",labelsize=0.5)
Hi there, I'm trying to do a bibliometric analysis with your tool and found out a weird error that happens when I try to do a co-citation analysis, from the example provided.
As soon as I use biblioNetwork with network="authors" ` data(scientometrics)
NetMatrix <- biblioNetwork(scientometrics, analysis = "co-citation", network = "references", sep = ";")
net <- networkPlot(NetMatrix, n = 30, type = "kamada", Title = "Co-Citation",labelsize=0.5) ` Says
Error in crossprod(x, y) : requires numeric/complex matrix/vector arguments
And happens with anything but references
