[1] 8 32 ##should be 8 33.5
I believe it has to be done explicitly by finding all the differences
and choosing those n with minimum values, depending on what n you
want.
Note that the problem is incompletely spe
Hi,
Perhaps this works:
a[sapply(b,function(x) which.min(abs(x-a)))]
#[1] 8 32

Dear All,
would you please provide your thoughts on the following:
let us say I have:
a <-c(1,5,8,15,32,69)
b <-c(8.5,33)
and I would like to extract from "a" the two values that are closest to the
values in "b", where the length of this vectors may change but b will allways
be shorter than "a
