A concept set can be represented as either a codelist or a concept set expression. A codelist is a named list, with each item of the list containing specific concept IDs.
condition_codes <- list("diabetes" = c(201820, 4087682, 3655269),
"asthma" = 317009)
condition_codes <- newCodelist(condition_codes)
#> Warning: ! `codelist` contains numeric values, they are casted to integers.
condition_codes
#>
#> - asthma (1 codes)
#> - diabetes (3 codes)
A codelist must be named
condition_codes <- list(c(201820, 4087682, 3655269))
newCodelist(condition_codes)
#> Error in `newCodelist()`:
#> ! `codelist` must be named.
#> `codelist` must be a list with objects of class numeric, integer, and
#> integer64; it can not contain NA; it has to be named; it can not be NULL.
And a codelist cannot have missing values
A concept set expression provides a high-level definition of concepts that, when applied to a specific OMOP CDM vocabulary version (by making use of the concept hierarchies and relationships), will result in a codelist.
condition_cs <- list(
"diabetes" = dplyr::tibble(
"concept_id" = c(201820, 4087682),
"excluded" = c(FALSE, FALSE),
"descendants" = c(TRUE, FALSE),
"mapped" = c(FALSE, FALSE)
),
"asthma" = dplyr::tibble(
"concept_id" = 317009,
"excluded" = FALSE,
"descendants" = FALSE,
"mapped" = FALSE
)
)
condition_cs <- newConceptSetExpression(condition_cs)
condition_cs
#>
#> - asthma (1 concept criteria)
#> - diabetes (2 concept criteria)
As with a codelist, a concept set expression must be a named list and cannot have missing elements.
condition_cs <- list(
dplyr::tibble(
"concept_id" = c(201820, NA),
"excluded" = c(FALSE, FALSE),
"descendants" = c(TRUE, FALSE),
"mapped" = c(FALSE, FALSE)
))
newConceptSetExpression(condition_cs)
#> Error in `newConceptSetExpression()`:
#> ! `x` must be named.
#> `x` must be a list with objects of class tbl; it can not contain NA; it has to
#> be named; it can not be NULL.
condition_cs <- list(
"diabetes" = dplyr::tibble(
"concept_id" = c(201820, NA),
"excluded" = c(FALSE, FALSE),
"descendants" = c(TRUE, FALSE),
"mapped" = c(FALSE, FALSE)
),
"asthma" = dplyr::tibble(
"concept_id" = 317009,
"excluded" = FALSE,
"descendants" = FALSE,
"mapped" = FALSE
)
)
newConceptSetExpression(condition_cs)
#> Error in `newConceptSetExpression()`:
