Getting the Slots from a S4 Object

This helper function extracts requested slots from the S4 class object. It is a simple wrapper of methods::slot() function.

Usage

h_slots(object, names, simplify = FALSE)

Arguments

object

(S4)
an object from a formally defined S4 class.

names

(character)
a vector with names of slots to be fetched. This function assumes that for every element in names, there exists a slot of the same name in the object.

simplify

(flag)
should an output be simplified? This has an effect if and only if a single slot is about to be extracted, i.e. names is just a single string.

Value

list with the slots extracted from object according to names, or single slot if simplification is required and possible.
