Examples

# add interactive maps to a ggplot -------
crimes <- data.frame(state = tolower(rownames(USArrests)), USArrests)

# create tooltips and onclick events
states_ <- sprintf("<p>%s</p>",
                   as.character(crimes$state) )
table_ <- paste0(
  "<table><tr><td>UrbanPop</td>",
  sprintf("<td>%.0f</td>", crimes$UrbanPop),
  "</tr><tr>",
  "<td>Assault</td>",
  sprintf("<td>%.0f</td>", crimes$Assault),
  "</tr></table>"
)

onclick <- sprintf(
  "window.open(\"%s%s\")",
  "http://en.wikipedia.org/wiki/",
  as.character(crimes$state)
)
