The function providing access to KTH Publications API data can provide some overview stats, list the active public users, active users with publications and more. Some usage examples:

kth_publications("stats")
#> <KTH API call for stats>
#> $activeUsers
#> [1] 3397
#> 
#> $publicUsers
#> [1] 1147

# top 5 active public users with publication counts

  setNames(., nm = c("count", "kthid", "username")) %>%
  arrange(desc(count)) %>%
  select(-kthid) %>%
  slice(1:5) %>%
  knitr::kable()
