Based on this discussion #504 (comment) , I verified that the tooltip in the case below works if trigger='item' but not if trigger='axis' .

library(echarts4r)
library(dplyr)

mtcars |>
  mutate(label = paste("Tooltip label:", hp + disp)) |>
  e_charts_(x = 'wt') |>
  e_line_(serie = 'qsec') |>
  e_add_nested('extra', label) |>
  e_tooltip(
    trigger = "axis",
    formatter = htmlwidgets::JS(
      'function(params){
        return params.data.extra.label;
      }'
    )
  )
