Argument tooltips of method tooltips() expects list of character vectors - fails for numeric values.

[ablaette]

See the following example. I think it is a common scenario that you want to use tooltips to inspect values of word weights. An implicit coercion to of values passed to a character vector would solve the issue.

library(polmineR)

use("RcppCWB")

corpus("REUTERS") %>% 
  subset(id == "127") %>% 
  read() %>% 
  highlight(list(lightgreen = "oil")) %>% 
  tooltips(list(lightgreen = 0.5))

corpus("REUTERS") %>% 
  subset(id == "127") %>% 
  read() %>% 
  highlight(list(lightgreen = "oil")) %>% 
  tooltips(list(lightgreen = "0.5"))
