IntervalMatrix
objectThis function allows to get the number of rows of an interval-valued matrix.

This function returns a single numeric value indicating the number of
rows of an interval-valued matrix. Therefore, this function always
returns an integer
object whose length is one.

The number of rows of an IntervalMatrix
object can be obtained along
with the number of columns through dim()
function. In an
analogous way, for getting the number of columns of an IntervalMatrix
object, ncol()
function can be used.
## Some nrow() examples
data1 <- matrix(c(0, 1, 2, 3, 0, 3, 4, 9), 2, 4)
m1 <- IntervalMatrix(data1)
nrow(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)
nrow(m2)
