Examples

# Get details about all PGS Catalog data releases thus far:
all_releases <- get_releases(date = 'all', progress_bar = FALSE)

#
# Subsetting by position
#
# Releases are, by default, sorted by date in descending order, thus the
# first PGS Catalog release is in the last position of the returned
# `all_releases` object. Here's how you can extract that first release (last
# position in `all_releases`):
all_releases[n(all_releases)]

#
# Subsetting by date (character)
#
date_of_interest <- '2021-06-11'
class(date_of_interest)
all_releases[date_of_interest]

#
# Subsetting by date (Date object)
#
date_of_interest <- as.Date('2021-06-11')
class(date_of_interest)
all_releases[date_of_interest]
