    ## Convert frequencies to success/failure data:
    ##
    citations.sf <- countsToBinomial(citations)
    names(citations.sf)[1:2] <- c("journal1", "journal2")

    ## Standard Bradley-Terry model fitted to these data
    citeModel <-  BTm(cbind(win1, win2), journal1, journal2,
                      data = citations.sf)
