Get CalCOFI Database as dm Object with Relationships

Source: R/database.R
cc_get_dm.Rd

Returns a dm object with primary keys and foreign keys applied from the relationships.json sidecar file included in frozen releases. This enables schema visualization via dm::dm_draw() and relationship- aware operations.

Usage

cc_get_dm(version = "latest", con = NULL)

Arguments

version

Version string (e.g., "v2026.02") or "latest" (default)

con

Optional existing DuckDB connection. If NULL (default), calls cc_get_db(version) to create one.

Value

A dm object with PKs and FKs applied

Examples

if (FALSE) { # \dontrun{
dm <- cc_get_dm()
dm::dm_draw(dm, rankdir = "LR", view_type = "all")

# use existing connection
con <- cc_get_db()
dm <- cc_get_dm(con = con)
} # }
