Extracts phenotypic fields from the UKB Research Analysis Platform dataset
and returns a data.table. All instances and arrays are returned for
each requested field. Column names are kept as-is (e.g.
participant.p53_i0); use the clean_ series for renaming.
Usage
extract_pheno(field_id, dataset = NULL, timeout = 300)
Arguments
- field_id
(integer) Vector of UKB Field IDs to extract, e.g.
c(31, 53, 22189). eid is always included automatically.
- dataset
(character) Dataset file name. Default: NULL
(auto-detect from project root).
- timeout
(integer) Extraction timeout in seconds. Default: 300.
Value
A data.table with one row per participant. Column names
follow the participant.p<id>_i<n>_a<m> convention.
Fields not found are skipped with a warning.
Examples
if (FALSE) { # \dontrun{
df <- extract_pheno(c(31, 53, 21022))
df <- extract_pheno(c(31, 53, 20002), dataset = "app12345_20260101.dataset")
} # }
