R help - Nov 2013 - GLMNET warning msg

Hi I'm getting the following warning msg after ?cv.glmnet and I'm
wondering what it means...
 
dim(x) 10   12000; 
dim(y) 10; #two groups case=1 and control=0
cv.glmnet(x, y)

Warning message:
Option grouped=FALSE enforced in cv.glmnet, since < 3 observations per fold

 
Thanks,

It means that 10/10 = 1 < 3.

It also means that what you're trying to do (fitting 10 cases to 12000
variables) is ridiculous (assuming I understand your message
correctly).


Cheers,
Bert
