HI Andras,
Sorry, I misunderstood your question:

Try this:
?sapply(sapply(b,function(x) d[x<d]),`[`,1)
#[1] 12 36 36

Arun,

thank you. Looking at it I am wondering if there is a way to get 36 in the result instead of
the 24. The 2nd value in b is 24.6, therefore the 1st value greater then that in d is 36.

appreciate the help,

Andras

May be this helps:

d[cumsum(sapply(d,function(x) any(x>b)))>=1]
#[1] 12 24 36

Dear All,

would you please help with the following:
let us say I have:

a <-c(0,1,12,13,24,25,36,37)
b <-c(6,24.6,27)
#then I extract every 2nd element from "a"
d <-a[seq(1, length(a), 2)]

and what I need help with is to extract the 1st value from d
that is greater than the values in b, so as a result I
should have "f" as:

f <-c(12,36,36)

appreciate the insights,

thank you,

Andras
