as.IntervalData {IntervalQuestionStat} | R Documentation |
This function allows to coerce a real number stored as a single
numeric
object to a degenerate interval formed only by this real
number saved as an IntervalData
instance.
## S4 method for signature 'numeric'
as.IntervalData(object)
object |
A single real number stored as a single |
Single real numbers could be seen as particular cases of interval-valued data where each interval's lower and upper bounds are equal or, alternatively, its spread is zero.
This function returns a degenerate interval saved as an object
of class IntervalData
.

## Transform a single real-valued number into an interval
## In particular, degenerate interval {1} is defined.
