right now I have a vector of about 1000 points. I'd like to iterate through
each of these points and and test if it is greater than a certain value and
if not, throw it out.

x=vector
y=empty vector
j=0

for i (0..length[vector])
     if x[i] > 10
          y[j] = x[i]
          j++

Thats basically some pseudo code of what I want to do.  Any suggestions?

This Is R not C. 

y <-  x[x>10]

I recommend you to have a look into the R intro where you can find some 
quite basic manipulations with objects.
