plot_relationships(df, ..., min.freq = 25, threshold = 0.1)

Arguments

df

a dataframe with paper results

...

                          how = "all")
df <- read_multidoc(my_url)   # create a dataframe of papers
(tf <- term_frequency(df))    # create a term frequency table
min_freq <- min(head(tf, 20)$freq)
plot_relationships(df, min.freq = min_freq, threshold = 0.075)
