List available partitions under a base directory

Usage

st_list_parts(base, filter = NULL, recursive = TRUE)

Arguments

base

Base dir

filter

Partition filter. Supports three formats:

  • Named list for exact matching: list(country = "USA", year = 2020)

  • Formula with expression: ~ year > 2010 or ~ country == "COL" & year >= 2012

  • NULL for no filtering (default)

recursive

Logical; search subdirs (default TRUE)

Value

A data.frame with columns: path plus one column per partition key

Examples

if (FALSE) { # \dontrun{
# List all partitions
st_list_parts("data/parts")

# Exact match (backward compatible)
st_list_parts("data/parts", filter = list(country = "USA"))

# Expression-based (flexible)
st_list_parts("data/parts", filter = ~ year > 2010)
st_list_parts("data/parts", filter = ~ country == "COL" & year >= 2012)
} # }
