A random sample from PubMed

Description

Identify a random sample of articles from PubMed. Note that this function retrieves the currently available articles from PubMed, so it requires internet connection to search PubMed and download the results. Depending on the connection and selected years, this can take at least a few minutes to run. Note that these samples will change with changes in the data provided by PubMed, for which reason a "Data sampled" column is added as a time-stamp. Please also consider using a seed to improve reproducibility and do not run this function repeatedly.

Usage

mt_sample_pubmed(n = 1000, year_min = 2020, year_max = 2020, seed = NULL)
