Load Example EDC Data

Loads bundled clinical trial example data for use in examples and vignettes. The data simulates a Phase II study (STUDY-001) with 48 subjects enrolled over 6 months across four SDTM-flavored domains.

Usage

datom_example_data(domain = c("dm", "ex", "lb", "ae"), cutoff_date = NULL)

Arguments

domain

One of "dm" (demographics, 48 rows), "ex" (exposure, 48 rows), "lb" (labs, ~720 rows: 3 visits x 5 tests per subject), or "ae" (adverse events, ~80 rows).

cutoff_date

Optional date string ("YYYY-MM-DD") to filter rows whose primary date column is on or before this date, simulating a point-in-time EDC extract. The date column used per domain: RFSTDTC (dm), EXSTDTC (ex), LBDTC (lb), AESTDTC (ae).

Value

A data frame.

Examples

# Full demographics
dm <- datom_example_data("dm")

# Month-3 snapshot (subjects enrolled by 2026-03-28)
dm_m3 <- datom_example_data("dm", cutoff_date = "2026-03-28")

# Labs collected through Month 3
lb_m3 <- datom_example_data("lb", cutoff_date = "2026-03-28")
