cbind {IntervalQuestionStat}

Combine IntervalList and IntervalMatrix objects by columns

Description

This function allows to combine a sequence of lists and matrices of intervals, that is, IntervalList and IntervalMatrix objects, by columns, and store the result as an IntervalMatrix instance.

Usage

## S4 method for signature 'IntervalListOrIntervalMatrix'
cbind(..., deparse.level = 1)

Arguments

...

A sequence of lists or matrices of nonempty compact real intervals stored as IntervalList or IntervalMatrix objects, respectively.

deparse.level

Currently not used (put here to match the signature of the base implementation).

Value

This function returns a matrix of interval-valued data stored as an IntervalMatrix object.

Examples

## Some cbind() examples
list1 <- IntervalList(c(0, 3), c(4, 5))
list2 <- IntervalList(c(3, 0), c(7, 4))
cbind(list1, list2)

matrix1 <- IntervalMatrix(matrix(c(0, 1, 2, 3, 0, 3, 4, 9), 2, 4))
matrix2 <- IntervalMatrix(matrix(c(1, 5, 2, 6, 0, 1, 2, 3), 2, 4))
cbind(matrix1, matrix2)

cbind(list1, matrix1)
