Rank of a matrix?
Hello everyone,
this is a very simple question but I could not find the answer. :-(
Is there any function in R for calculating the rank of a matrix?
(In the sense of the dimension of the vectorial space that spans)
Thank you in advance!
Manuel

Reference Classes copy(shallow=FALSE) unexpected behavior.
...ile I
was expecting the shallow=FALSE to perform a deep copy and create copies of
those objects as well.
As I''m new with reference classes this causes me a lot of confussion. Is
this a bug, is this a feature?
Any insights about the matter are welcome
Thanks in advance

train nnet
Hi R-helpers,
Can some one tell me how to train 'mynn' of this type?:
mynn <- nnet(y ~ x1 + ..+ x8, data = lgist, size = 2, rang = 0.1,
decay = 5e-4, maxit = 200)
I assume that this nn is untrained, and to train I have to split the
original data into train:test data set,
do leave-one-out refitting to refine the weights (please straighten
this up if I was wrong).
I just don't know
