x=c(5, 8, 28, 29, 30) y=c(5, 8, 28, 29, 31) How can we compare these two vectors, whether each element is exactly matched with the elements in the other vector ? How can we get the non matched elements from both the vectors? Can anyone help? ________________________________ Notice: The information contained in this electronic mail message is intended only for the use of the designated recipient.

Hi krishna, 1.How can we compare these two vectors,whether each element is exactly matched with the elements in the other vector? x=c(5, 8, 28, 29, 30) y=c(5, 8, 28, 29, 31) z<-(x %in% y)> z[1] TRUE TRUE TRUE TRUE FALSE (OR) z<-identical(x,y)> z[1] FALSE (OR) to get values that are matching z<-x[x %in% y]> z[1] 5 8 28 29 2.How can we get the non matched elements from both the vectors? z<-setdiff(x,y)> z[1] 30 i hope this will help Regards Ramakanth Reddy Guntuka --------------------------------------------------------------------------------------- Life Sc.
