Comparing Vectors Values: 1 element with all other

Question

I\'m wondering how I can compare 1 element of a vector with all elements in the other vector. As an example: suppose

x <- c(1:10)  
y <- c(10,11,12,13,         


        

Answer 1

If you want to compare each element of x to y, usually one of the 'apply' functions will help.

As follows:

x <- c(1:10)

y <- c(10,11,12,13,14,1,7)

sapply(x,function(z){z==y})

Column i in the output is result from x[i]==y.

Is this what you're looking for?
