Topic-correlation network as an igraph graph — topic_corr

Exports the positive-correlation topic network as an igraph object (stm issue #242), with topic prevalence and FREX labels as vertex attributes and the positive correlations as edge weights — ready for igraph/ggraph layouts.

Usage

topic_corr_graph(x, model = NULL, nlabel = 3L)

Arguments

x: A faSTM_topiccorr (from topicCorr()) or a faSTM fit.
model: The fit, if x is a bare correlation object (for vertex prevalence/labels).
nlabel: Top FREX words per topic for the vertex label.

Value

An undirected igraph graph.
