mt_sample_pmc R Documentation
A random sample from PubMed Central (PMC)
Description
Identify a random sample of articles. Note that this function retrieves the
list of currently available articles from PMC, so it requires internet
connection to download a file of ~550 MB at the time of writing and,
depending on the connection, it will take about a minute to run. Note
that these samples will change with changes in the data provided by PMC,
for which reason a "Data sampled" column is added as a time-stamp.
Usage
mt_sample_pmc(n = 1000, year_min = 2016, year_max = 2020, seed = NULL)
Arguments
n
The number of articles to sample, as a numeric.
year_min
The minimum year to sample from inclusive, as a numeric.
year_max
The maximum year to sample from inclusive, as a numeric.
seed
Provide a seed for a reproducible sample, as a numeric.
Value
A tibble of randomly sampled articles and their PMCID, PMID, DOI,
Journal Title, ISSN, eISSN, Year, Volume, Issue, Page and Date sampled.
Date sampled is in yyyy-mm-dd.
