Hello all,
given two vectors X and Y I'd like to receive a vector Z which
contains, for each element of X, the index of the corresponding
element in Y (or NA if that element isn't in Y).
Example:
x - c(4,5,6)
y - c(10,1,5,12,4,13,14)
z - findIndexIn(x, y)
z
[1] 5 3 NA
1st element of z is 5,
Robert,
Try
match(x, y)
HTH,
Jorge.-

Hi guys,
like so often, the answert came to me minutes after posting. pmatch()
does exactly what I need. match() gives the values of the elements,
but not their positions.
Thanks,

Hello,
?match
x - c(4,5,6)
y - c(10,1,5,12,4,13,14)
match(x,y)
[1] 5 3 NA
Hope this helps,
