[R] if statement error

[mike waters]

Jenny,
are there any missing values in your vectors? If so, what effect do you
think this will have on an expression like that required by the if statement
that must resolve fully to either true or false?

Regards,

Mike

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!

Jen





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
