Let x be the vector for the height of fathers 

x <- c(180.3, 177.4, etc)

and y be the height of the corresponding sons 

y <- c(179.5, 178.5, etc)

I now want to create a subset of fathers whose height is within 2.5cm of x=182 with the corresponding sons. How do I do this?

    Did you try anything? Where exactly did you get suck? It's easier to help you if you include a simple [reproducible example](https://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example) with sample input and desired output that can be used to test and verify possible solutions. Including parts like "etc" isn't very useful since that's not reproducible. – MrFlick Jan 24 '20 at 20:17

We can create a logical vector to subset the 'x'

i1 <- x >= (182 - 2.5) & x < (182 + 2.5)
x1 <- x[i1]
y1 <- y[i1]
