Nice one - didn't think of the array at all as my brain was fixated on lists...

Hello everybody
Sorry if such a question has already been posted somewhere, but I wasnât able
to find an answer yet.
Iâm trying to generate random numbers for illustration purposes.
The random numbers should satisfy a multiple regression equation, for example:
z = 0.3 + 0.05 * x + 1.5 * y
(1) you need to examine the rnorm function, enter
?rnorm()
(2) when you review the documentation produced by entering the command
above, you will see that the rnorm function needs three parameter, the
number of values to generate, the mean of the numbers to be generated,
and the SD (standard
Thanks william,
I got it now...

It would be nice if you told us what an OC curve is.
If it is a Operations Curve or something like it have a look at the pROC
package. It may do what you want. If that's not it, please actually tell us the
names of the curves not just the initials.

Dear list,
I am using glmnet. I have no idea what this error is telling me.
Here's my code,
bob - matrix(rnorm(100*180), nrow=180)
yyy - rnorm(180)
fit1 - cv.glmnet(bob, yyy, family=mgaussian)
Error in rep((Intercept), nrow(a0)) : invalid 'times' argument
In fact, I peeked inside cv.glmnet()

Antonio-
What exactly do you want as output? You stated you wanted a scatter plot,
but which variable do you want on the X axis and which variable do you want
on the Y axis?

You can use the traceback function to see where the error is:

yyy - rnorm(180)

I thought you want to compare between the rows of two columns even if their
corresponding values fall in the same row.
fun3- function(mat){
indmat-combn(seq_len(ncol(mat)),2)

clever HPC-optimized code would care about: is there a quantum
