splashr has gained some new functionality since the introductory post. First, there’s a whole new Docker image for it that embeds a local web server. Why? The main request for it was to enable rendering of htmlwidgets:

splash_vm <- start_splash(add_tempdir=TRUE)

DiagrammeR("
  graph LR
    A-->B
    A-->C
    C-->E
    B-->D
    C-->D
    D-->F
    E-->F
") %>% 
  saveWidget("/tmp/diag.html")

splash("localhost") %>% 
  render_file("/tmp/diag.html", output="html")
## {xml_document}
## 
## [1] \n\n\n
