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

And drop the second ";". Also, don't forget that "return x" is wrong [it took me a long time to figure out that R != C, and it's just return(x)] Alberto Monteiro

This works for me below, but it give the message you mentioned if you uncomment second line. Dieter ------------- beta1 = beta2 = theta1 = theta2 = 1.0 #beta1 = NULL real.d = runif(35) real.b = runif(35) r=corr=0 if( length(real.d)>=30 && length(real.b)>=30 && beta1*beta2*theta1*theta2>0 ) { r <- 1; corr <- 1; }
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,

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

Jenny This following example works:> real.d <- rep(NA,30) > real.b <- rep(NA,30) > b1=runif(1); b2=runif(1); t1=runif(1); t2=runif(1) > if (length(real.d)>=30 && length(real.b)>=30 &&b1*b2*t1*t2>0){bool=TRUE}> bool[1] TRUE But this one doesn't:> real.d <- rep(NA,30) > real.b <- rep(NA,30) > b1=runif(1); b2=runif(1); t1=runif(1); t2=NA > if (length(real.d)>=30 && length(real.b)>=30 &&b1*b2*t1*t2>0){bool=TRUE} Error in if (length(real.d) >= 30 && length(real.b) >= 30 && b1 * b2 * : missing value where TRUE/FALSE needed>NA's in the vector make no difference. && is correct. So, it appears at least one of your scalars is missing JFL -----Original Message----- From: r-help-bounces at stat.math.ethz.ch [mailto:r-help-bounces at stat.math.ethz.ch] On Behalf Of Jenny Stadt Sent: Tuesday, October 17, 2006 12:19 PM To: r-help at stat.math.ethz.ch Subject: [R] if statement error Hi List, I was not able to make this work.
