This package provides a way to programmatically retrieve altmetrics from various publication types (books, newsletters, articles, peer-reviewed papers and more) from altmetric.com. The package is really simple to use and only has two major functions:

  • altmetrics - Pass it a doi, isbn, uri, arxiv id or other to get metrics
  • altmetric_data Pass it the results from the previous call to get a tidy data.frame

Quick Tutorial

Obtaining metrics

There was a 2010 paper by Acuna et al that received a lot of attention on Twitter. What was the impact of that paper?

library(rAltmetric)
acuna <- altmetrics(doi = "10.1038/465860a")
acuna
#> Altmetrics on: "Metrics: Do metrics matter?" with altmetric_id: 385053 published in Nature.
#>                         stats
#> cited_by_fbwalls_count      3
#> cited_by_feeds_count        3
#> cited_by_gplus_count        2
#> cited_by_msm_count          1
#> cited_by_policies_count     1
#> cited_by_posts_count       31
#> cited_by_tweeters_count    20
#> cited_by_accounts_count    30

Data

To obtain the metrics in tabular form for further processing, run any object of class altmetric through altmetric_data() to get a data.frame that can easily be written to disk.

You can save these data into a clean spreadsheet format:

acuna_data <- altmetric_data(acuna)
readr::write_csv(acuna_data, path = 'acuna_altmetrics.csv')

Gathering metrics for many DOIs

For a real world use-case, one might want to get metrics on multiple publications. If so, just read them from a spreadsheet and llply through them like the example below.

library(rAltmetric)
library(magrittr)
library(purrr)
 
 
ids <- list(c(
  "10.1038/nature09210",
  "10.1126/science.1187820",
  "10.1016/j.tree.2011.01.009",
  "10.1086/664183"
))
 
alm <- function(x)  altmetrics(doi = x) %>% altmetric_data()
 
results <- pmap_df(ids, alm)
# This results in a data.frame with one row per identifier.
