[R] Loop doesn't work

2009-12-01 Thread Trafim 
Hi everybody,

I have the following problem, the following code seems to run only once for
i and j and for k from one to M.
Doesn't R for increase the argument by itself?

for (i in 1:N){
 for (j in 1:(Tk-1)){
  if((XGrid[i]  Xk[j+1])(Xk[j] = XGrid[i])){
for (k in 1:M){
   if ((RBins[k]=Rk[j+1])(Rk[j+1]RBins[k+1])){
  GR[k] - +1
   }
}
  }
 }
}

Thanks a lot

 Of course it does. Try this, which is something we call a complete
reproducible example:

N=10
for(i in 1:N){
 print(i)
}

How do we know your N isn't 1 and your Tk isn't 2?
