R: Rank of a Matrix
In matlib: Matrix Functions for Teaching and Learning Linear Algebra and Multivariate Statistics
R R Documentation
Rank of a Matrix
Description
Returns the rank of a matrix X, using the QR decomposition, QR.
Included here as a simple function, because rank does something different
and it is not obvious what to use for matrix rank.
Usage
R(X)
Arguments
X
a matrix
Value
rank of X
See Also
qr
Examples
M <- outer(1:3, 3:1)
M
R(M)
M <- matrix(1:9, 3, 3)
M
R(M)
# why rank=2?
echelon(M)
set.seed(1234)
M <- matrix(sample(1:9), 3, 3)
M
R(M)
