Hi,   

 my vector V<- c(1,0.5,0.06,0.056,0.01,0.04,0.4,0.9,0.82,0.1)  

  if( V > 0.5) { V <- 1 - V }  

I get a warning saying only the first element will be used in comparing (if V > 0.5). However, my results tell me vis-versa ,it actually compares every element of the vector V with 0.5 and that is waht i want it to do. Using a for loop is expensive and time consuming since my actual vector is 15000 values.  

Any help to rectify the warning i get is appreciated.  

Thank You.
