Set code type context — with

with_type() temporarily sets the active code type so that query functions inside code use it without needing an explicit type = argument.

Convenience wrappers (icd10(), sct(), etc.) call with_type() for each supported code type.

Usage

with_type(type, code)

icd10(code)

icd9(code)

read3(code)

read2(code)

sct(code)

opcs4(code)

phecode(code)

read2_drugs(code)

bnf(code)

dmd(code)

data_coding_3(code)

data_coding_4(code)

data_coding_5(code)

data_coding_6(code)

Arguments

type: A string naming the code type (e.g. "icd10", "sct"). This corresponds to the type argument accepted by query functions such as CODES(), CHILDREN(), and MAP().
code: The expression to evaluate within the code type context.

Value

The result of evaluating code.

Examples

if (FALSE) { # \dontrun{
with_type("icd10", DESCRIPTION("diabetes"))
icd10(DESCRIPTION("diabetes"))
bnf(CODES("0204 << Beta-Adrenoceptor Blocking Drugs >>"))
sct(
  CHILDREN(
    "770765001 << Proliferative retinopathy of right eye due to diabetes mellitus (disorder) >>"
  )
)
} # }
