Hi List,

I was not able to make this work. I know it is a simple one, sorry to bother. Give me some hints pls. Thanks!

if(length(real.d)>=30 && length(real.b)>=30 && beta1*beta2*theta1*theta2>0 )

{ r <- 1;  corr <- 1;  }


real.d and real.b are two vectors, beta1,beta2,theta1,and theta2 are constants. The error occurred like this:


Error in if (length(real.d) >= 30 && length(real.b) >= 30 && beta1 * beta2 *  : 
        missing value where TRUE/FALSE needed
