Get the number of rows and columns of an IntervalMatrix object

Description

This function allows to get the number of rows and columns of an interval-valued matrix.

Usage

## S4 method for signature 'IntervalMatrix'
dim(x)

Arguments

x	A matrix of interval-valued data stored as an IntervalMatrix object.

Value

This function returns a bidimensional vector with the number of rows and columns, respectively, of an interval-valued matrix. Therefore, it always returns an integer object whose length is two.

The IntervalQuestionStat package also allows to obtain the number of rows and columns of an IntervalMatrix object separately through nrow() and ncol() functions, respectively.

Examples

## Some dim() examples

data1 <- matrix(c(0, 1, 2, 3, 0, 3, 4, 9), 2, 4)
m1 <- IntervalMatrix(data1)
dim(m1)

data2 <- matrix(c(1, 5, 3, 2, 6, 4, 0, 1, 3,
                  2, 3, 9, 4, 3, 7, 5, 6, 8), 3, 6)
m2 <- IntervalMatrix(data2)
dim(m2)
