Dear All,
 
sorry, got stuck again on the following: let us say we have:
 
a <-c(1:5)
b <-c(6:10)
d <-cbind(a,b)
 
 
from d I would like to remove total number of rows based on the length of f. So 
if:
 
f <-c(1)
 
my result is working great with the following solution:
 
d[-length(f),]
 
so I get:     a  b
[1,] 2  7
[2,] 3  8
[3,] 4  9
[4,] 5 10 but if I do: f <-c(1,2) then I get:      a  b
[1,] 1  6
[2,] 3  8
[3,] 4  9
[4,] 5 10 which tells us ideed, the code works well:-), but it is not what I 
need Instead, I wanted to remove row #1 adn row#2 from the matrix to get: [1,] 
3  8
[2,] 4  9
[3,] 5 10  as the end result. Please provide your insights to solve this 
problem.  Any input would be greatly appreciated, thanks, Andras
