Error .. missing value where TRUE/FALSE needed

Question

I have been trying to run this code (below here) and I have gotten that message \"Error in if (temp[ii] == 0) { : missing value where TRUE/FALSE needed\"...

temp         


        

Answer 1

Your problem is that temp[ii] is returning NA because ii goes out of bounds:

ii = i + 1:tm     #Your declaration for ii
ii = 1:tm + 1:tm  #Evaluates to

So ii will definitely be larger than tm (and therefore length(temp) at some point.

In order to better understand/debug for loops, consider printing just the indices:

for(i in 1:tm)
{
    print(i)
    for(ii in i + 1:tm)
        print(ii)
}
