I think the reason is that 1 is compared to xn and 4 is compared to yn seperately. Could anyone tell me how I can get a single result of the comparson between a vector and a row of the matrix? for example£¬ c(1,1) is one row of the matrix but c(1,4) is not. I tried to write a loop but it seems long for this simple problem Thank you very much!!! [[alternative HTML version deleted]]

I appreciate anyones advice on this. I JUST found (after roughly 6 months of studying R) Luke Tierney's note on "Finalization and Weak References in R". From the developers page, this note is listed as...
