Type of the state abstract domain the semantics are defined for
Optional ReadonlyaccessThe abstract semantics of access calls, such as x[1] or x$id
Optional ReadonlyconditionThe abstract semantics of conditions, refining the abstract state in the branches guarded by a call of the respective function
Optional ReadonlyconstantsThe abstract semantics of the different types of R constants
Optional ReadonlyfunctionThe abstract semantics of normal function calls, such as data.frame(id = 1:5)
Optional ReadonlyreplacementThe abstract semantics of replacement calls, such as names(x) <- "id"
A declarative definition of the abstract semantics of an abstract domain, mapping R constants and concrete R functions to the semantics to apply for them (see ValueSemantics).
