Compare two vectors without a loop

[yiwu ye <yiwu21111958@yahoo.com>]

Dear list members,

 

suppose I have:

x y

1 3

2 4

3 5

4 6

5 6

I want to make a comparison between x and y, and to produce a new vector like

z

T

T

T

F

F

so, I can know the first three elements of y, 3,4,5,can find the same value in x.

Could someone told how I can do it without a loop, please? Many thanks.

 

Yiwu
