altmetric.com
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

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")
#> doi
acuna
#> Altmetrics on: "Metrics: Do metrics matter?" with altmetric_id: 385053 published in Nature.
#> stats

#> cited_by_feeds_count 3
#> cited_by_gplus_count 2

#> cited_by_policies_count 1
#> cited_by_posts_count 31
#> cited_by_tweeters_count 20
#> cited_by_accounts_count 30Data
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.

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)
#>
#> Attaching package: 'purrr'
#> The following object is masked from 'package:magrittr':
#>
#> set_names
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)
#> doi
#> doi
#> doi
#> doi
# This results in a data.frame with one row per identifier.Further reading
