When I used your code I got > for(i in 1:150) + for(j in 1:150) + (average <-c( + (if(NO[i]==1) + {i*0} + else + {if(HA[i]==HA[j]) + {while(G[j]==1) + {mean(PT[j:(i-1)])}}}))) Error: object 'NO' not found ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ > > Also, if what I'm trying to do makes any sense and someone sees an > easier way of doing it, that would be great. And what really you are trying to do? Use R like C+? No way, forget it. R is R C+ is C+.
