Examples

# Drawn from the bundled corpus of real articles, which needs no key. That
# corpus is a complete harvest, so its rows per year are the publications
# per year its query returns.
by_year <- table(example_records$year)
tr <- tibble::tibble(
  query = "TITLE-ABS-KEY(graphene supercapacitor)",
  year = as.integer(names(by_year)),
  n = as.numeric(by_year)
)
class(tr) <- c("scopus_trend", class(tr))
