Dennis, Thanks for that. The problem now is that I am trying to use it in a for loop. Based on the example before, 2 entries are required after H[3] as specified by O. The problem is that when inserting values the length of the array changes so I don't know how to tell the loop that. This is what I have:
for (i in 1:length(H)) { if (o[i]>0) {append(H, -1, after = i-1)} } Any ideas how to create a loop that allows the inclusion of more than 1 value?
