serVis: View and/or share LDAvis in a browser

In cpsievert/LDAvis: Interactive Visualization of Topic Models

Description

View and/or share LDAvis in a browser.

Usage

serVis(json, out.dir = tempfile(), open.browser = interactive(),
  as.gist = FALSE, language = "english", encoding = getOption("encoding"),
  ...)

Arguments

json	character string output from createJSON.
out.dir	directory to store html/js/json files.
open.browser	Should R open a browser? If yes, this function will attempt to create a local file server via the servr package. This is necessary since the javascript needs to access local files and most browsers will not allow this.
as.gist	should the vis be uploaded as a gist? Will prompt for an interactive login if the GITHUB_PAT environment variable is not set. For more details, see https://github.com/ropensci/gistr#authentication.
language	Which language to use in visualization? So far: english or polish.
encoding	Sets the encoding to be used when writing the JSON file.
...	arguments passed onto gistr::gist_create

Details

This function will place the necessary html/js/css files (located in system.file("htmljs", package = "LDAvis")) in a directory specified by out.dir, start a local file server in that directory (if necessary), and (optionally) open the default browser in this directory. If as.gist=TRUE, it will attempt to upload these files as a gist (in this case, please make sure you have the gistr package installed as well as your 'github.username' and 'github.password' set in options.)

Value

An invisible object.
