I want to use RiTa.js in R language, but my code does not load the right library. How can I fix it?
Script
library(V8)
ct <- v8()
ct$source("https://cdnjs.cloudflare.com/ajax/libs/rita/1.1.51/rita-full.js")
ct$eval("var s = 'it was a dark and stormy night.';")
ct$eval("var r = new RiString(s);")
Result
Error in context_eval(join(src), private$context) : ReferenceError: RiString is not defined
I think you will just need to make a slight adjustment to get this up and running. The RiTa JavaScript expects to be in the browser with window
available. The default in R V8
is global
. Fortunately we can easily change with global="window"
argument.
library(V8)
ctx <- v8(global="window")
ctx$source("https://cdnjs.cloudflare.com/ajax/libs/rita/1.1.51/rita-full.js")
ctx$get("Object.keys(window)")
You should now see all the RiTa.js available for use.
