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

Re: [R] condition in triple summation

2015-10-19 Thread jim holtman 
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.

Re: [R] condition in triple summation

2015-10-19 Thread Sherouk Moawad via R-help 

| If for example I have a double sammation on (xj+xi)The first summation from 1 
to 3 And second summation is from 1 to 2If I put the condition of (i>j ) then 
the term (x1+x1) will not be included I need to cut the condition into tow 
parts If i>1 then i>jWhile if i=1 then i>=jSo that the term (x1+x1) is 
includedCan this be done or it's an imaginary casePlease help |
