runShiny error #20

Closed equihuam closed 10 years ago

equihuam commented 10 years ago

I am trying to run the examples but get this error:

Listening on http://127.0.0.1:7258 Joining by: Term Joining by: Error in eval(substitute(expr), envir, enclos) : object 'Freq2' not found Error: object 'Freq2' not found

The issued commands were: z <- with(APdata, check.inputs(K = 40, W = 10473, phi, term.frequency, vocab, topic.proportion)) with(z, runShiny(phi, term.frequency, vocab, topic.proportion))

Try starting a new session and run the following:

devtools::install_github("cpsievert/LDAvis")
data("APdata", package = "LDAvis")
z <- with(APdata, check.inputs(K = 40, W = 10473, phi, term.frequency, vocab, topic.proportion))
with(z, runShiny(phi, term.frequency, vocab, topic.proportion))

That being said, we're very close to introducing a new version that will deprecate the runShiny in favor of createJSON, so I encourage you to have a look at createJSON. This doesn't mean you won't be able to take advantage of shiny since it will be fairly easy to embed the viz in a shiny app.

By the way you can try out the development version with:

devtools::install_github("cpsievert/LDAvis", ref = "new")

In that version, createJSON has changed to newJSON, but it should change back to createJSON before we formally introduce these changes.

Your first suggestion worked fine!!!!! well I did also upgraded R to 3.1.2. Will look into the createJSON now. Thank you very much.
