Dear friends,
Hope you are doing great. I need to perform a k-fold cross validation
analysis on the famous iris dataset, with k = 5.
Now, the model I am using is a multinomial logit, because the dependent
variable is species and it has three classes (setosa, versicolor and
virginica).
The packag
Thankyou very much. It worked.

Hi all,
We are conducting network metaanalysis of 3 treatments compared to placebo
using netmeta analysis. We have mean sd values for an outcome. How do we
calculate z scores using netmeta package? Thank you

... and here is another version of Jeff's solution using the built in
row() and col() functions instead of explicitly creating the indices
(but his version generalizes to arbitrary arrays; this does not):
qq <- matrix(12:7, nrow =3) ## start with a non-sorted matrix
> qq
[,1] [,2]
[1,] 12

Combine order() to get the sorting per

I have this following simple dataset

structure(1:6, .Dim = 3:2, .Dimnames = list(c("1", "2", "3"),
c("1", "2")))
I want to extract row and column index of the sorted values of this matrix
For example,
sort(qq) command will execute the sorted values of this matrix as
7 matches
