There are at least two things I don't understand in your proposal:

1. How x and y variate? I mean, there is not x= or y= commands prior to 
enter for().
2. Whatever I set or not x and y, the code claims:

Error in x[i, ] : incorrect number of dimensions

Please, why to you use plot(x[i,],y[i,]) instead of plot(x,y)?

Thanks for your help,
