union.SNOMEDconcept: Set operations for SNOMEDconcept vectors

Description

The default set functions in the base package do not handle integer64 vectors correctly, so this package also provides new generic functions for union, intersect and setdiff, which enable the appropriate object-specific function to be called according to the class of the vector. This means that SNOMEDconcept vectors will remain as SNOMEDconcept vectors when these functions are used.

Usage

# S3 method for SNOMEDconcept
union(x, y)
union(x, y)
# S3 method for default
union(x, y)
# S3 method for SNOMEDconcept
intersect(x, y)
intersect(x, y)
# S3 method for default
intersect(x, y)
# S3 method for SNOMEDconcept
setdiff(x, y)
setdiff(x, y)
# S3 method for default
setdiff(x, y)

Value

an integer64 vector of SNOMEDconcept class

Arguments

x

SNOMEDconcept vector

y

SNOMEDconcept vector, or an object that can be coerced to SNOMEDconcept by as.SNOMEDconcept

  'Acute heart failure'), SNOMED = sampleSNOMED())
acute_left_right <- SNOMEDconcept(c('Acute heart failure',
  'Left heart failure', 'Right heart failure'),
  SNOMED = sampleSNOMED())
union(sys_acute, acute_left_right) 
intersect(sys_acute, acute_left_right)
