)

Arguments

con	BibEntry object to extract connections from.
entry	numeric index or character key of entry in bib to open.
open.field	character vector of fields to use in bib to open the BibEntry. Possible fields are any combination of “file”, “url”, “eprint”, or “doi”. “eprint” is implemented for eprinttype= “JSTOR”, “PubMed”, or “arXiv”. When multiple fields are specified, they are tried in the order they appear in the vector.
viewer	character string giving the name of the program to be used as hypertext browser. It should be in the PATH, or a full path specified. Alternatively, an R function to be called to invoke the browser. Defaults to getOptions("pdfviewer") if open.field = "file" and getOptions("browser"), otherwise.
