I am new to R and have some query.
I am having a dataset with binary output 0's and ones. But along with it it

But whenever there is a NA in an row the sum of the row is returned as NA
so I am not able to sum up the values.

I have tried every fix on my try or tryCatch that I have found on the

Test Case for Package
Hi,
I had a query for writing a test case for a package.
If we are testing a function then do we need to call that function for
testing; library(mypackage)? Is that any circular logic any way.
For eg. if I create a package mypackage, can I have a file mypackagetest in
the tests directory whose line is library(mypackage).
It would be helpful if I could get some input on this.

Naming dimnames in an array using the results of an expression

i'm struggling with naming in an array
diag.data is one of a series of 2x2 diagnostic testing arrays, with

drawn from a larger list object of 'results'
i can hard-code the names of the array using dimnames;
diag.data<-array(c(19,2,125,50),c(2,2)) #example to run - actually comes
