This function maps Unified Medical Language System (UMLS) codes to OncoTree codes.
Usage
umls_to_oncotree(
umls_code = NULL,
oncotree_version = "oncotree_latest_stable",
expand = FALSE
)Arguments
- umls_code
UMLS codes.
- oncotree_version
OncoTree database release version.
- expand
Whether to expand one-to-many mappings. If
TRUE, one-to-many mappings are expanded into several rows in the output.
Value
A tibble of two variables: umls_code and oncotree_code.
Examples
if (FALSE) {
# Leave `umls_code` empty to return mappings for all UMLS codes
umls_to_oncotree()
# Map a few selected OncoTree codes
umls_to_oncotree(umls_code = c('C0206642', 'C0600113', 'C0279654', 'C1707436'))
# Use `expand` to make sure the column `oncotree_code` is a character vector and
# not a list-column. One-to-many mappings will result in more than row with
# `oncotree_code` values repeated.
umls_to_oncotree(umls_code = c('C0206642', 'C0600113', 'C0279654', 'C1707436'), expand = TRUE)
