Community,
I have a question regarding the STM package for R and hope that you can help me find an answer.
In figure 7 of the vignette the authors present a graph, where the topic prevalence (for topic 7) over time can be seen. Is it possible to plot the same graph by adding two further lines: one for liberal and one for conservative?
Liberal and conservative are attributes of the variable "rating"
The plot in figure 7 shows you the topic proportion of one topic (in this case topic 7) over a time span of January 2008 to December 2008. Basically, this graph shows you how your topic is distributed over a specific time frame. You can plot other topics in this graph, so yes, you can add more lines, but you cannot add a variable, like liberal/conservative, to plot in this graph.
Also, you might want to have a look at this -- it would be useful to add a reproducible example for clarity
