Could this work with Rselenium?

[vnijs]

listviewer is really cool! I thought this would be great fit for Rselenium because it creates some difficult to navigate lists. I tried it out but get a bunch of warnings (see below) but no listviewer. Any ideas?

library(RSelenium)
pJS <- phantom()
remDr <- remoteDriver(browserName = 'phantomjs')
remDr$open(silent = TRUE)
remDr$navigate("http://vnijs.rady.ucsd.edu:3838/marketing")
webElems <- remDr$findElements("css selector", "label")
jsonedit(webElems)
remDr$close()
pJS$stop() 

Warning messages:
1: In FUN(X[[28L]], ...) :
converting an R function to JSON as null. To change this, define a method for toJSON() for a 'function' object.

It definitely can work, but RSelenium is loading RJSONIO and the not 28 pull request htmlwidgets does also, so I'm thinking that we'll need to explicitly call jsonlite::toJSON. jsonlite supports conversion of functions. Could you try this? Note, it might affect your shiny, but you can easily revert back.

devtools::install_github(c('jeroenooms/jsonlite', 'rstudio/shiny', 'yihui/htmlwidgets@jsonlite'))

I took another look at the list created by RSelenium. Link to a webElems list in an rda file linked below. This is much more complicated than I hoped. It is a list but each element is an S4 object with functions all over the place.

In case he is interested ... @johndharrison ... any thoughts on using listviewer with output lists from Rselenium? Figuring out what Rselenium scraped, where the result is, and how to retrieve it is not always clear to me so I thought a list viewer might be useful.

@abresler might also be interested in this

Yup!!

Other thing we need to do is wrap a tor option into rselenium I have hacks but it'd similar how we do elastic search but wanna try to avoid having to use terminal

Hi Guys,

Sounds interesting. When I began RSelenium only RJSONIO was available. For some private projects I have worked on I have used jsonlite and prefer it. I would think it could be a drop in replacement in the RSelenium code. I havent used listviewer but from the demo it looks neat.

@abresler if you can file an issue on RSelenium I can look into tor.
