Examples

## Not run: 
my_url <- make_search_url(query = "well test",
                          dc_type = "conference-paper",
                          from_year = 2017,
                          to_year   = 2018,
                          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)
