FAQ
Not sure I understand what your condition 'i > j > k' means in the context
of where each of the values is 1:3. The only value that meets that
condition is i =3, j=2 & k=1, but you said exclude any cases where the
values were equal to 1.


Can you clarify with an example what you mean.

If I'm summing over (i,j,k) each from 1 to 3

And I have condition that (i>j>k)

But I want to restrict this condition to only cases where i,j,k>1

Dear R-Expertsx=c(0,0.3, 0.5,0.6)sum(sapply(1:4, function(i)

I want to restrict the condition (i>j>k) to only those cases where
i>1&j>1&k>1In other words'if i=1 then i>=jif j=1 then j>=kother wise
i>j>kcan this be done using coding or notThank you
