Error in eval(expr, envir, enclos) : object 'topic.proportion' not found

Hi Mike,

For now you need to have a few objects in your global R environment (including 'topic.proportion') in order for runVis() to work.

From the help file for runVis():

Example using Newsgroup documents from http://qwone.com/~jason/20Newsgroups/

data("Newsgroupdata", package = "LDAvis")

Run the check inputs function:

z <- check.inputs(K=50, W=22524, phi=Newsgroupdata$phi, token.frequency=Newsgroupdata$token.frequency, vocab=Newsgroupdata$vocab, topic.proportion=Newsgroupdata$topic.proportion) for (i in 1:length(z)) assign(names(z)[i], z[[i]])

Set a seed to ensure k-means produces the same clusters every time you runVis()

set.seed(333) runVis()
