Hi Dr Sklyar, This is interesting to know - I have just noticed that it also happens every 100 points, there is another disjoint between 200 and 201. I have attached a file showing this.
The file was created using the following code:
> png("disjoint2.png")
> plot(1:210, type="l")
> dev.off()
Regards,
Richard
