Error: missing value where TRUE/FALSE needed

[nimarah]

Hi everyone

During run a special package, I encounter this error

Error in if (func.lambda(lower, X2, df, b = bb) * func.lambda(l.upper,  :
  missing value where TRUE/FALSE needed

main Code is

RMSEAfun <- function (X2, df, N, CI)
{
  bb <- (1 - CI)/2
  lower <- 0
  l.upper <- X2
  u.upper <- max(N, X2 * 5)
  if (func.lambda(lower, X2, df, b = bb) * func.lambda(l.upper,
                                                       X2, df, b = bb) > 0) {
    l.lambda <- 0
  }
  else {
    l.lambda <- uniroot(f = func.lambda, lower = lower, upper = l.upper,
                        X2 = X2, b = bb, df = df)$root
  }
  if (func.lambda(lower, X2, df, b = CI + bb) * func.lambda(u.upper,
                                                            X2, df, b = CI + bb) > 0) {
    u.lambda <- 0
  }
  else {
    u.lambda <- uniroot(f = func.lambda, lower = lower, upper = u.upper,
                        X2 = X2, b = CI + bb, df = df)$root
  }
  return(c(sqrt(l.lambda/(N * df)), sqrt(u.lambda/(N * df))))
}

How can i save my life?

It's impossible to answer without knowing func.lambda and all the arguments. You need to provide a reprex:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

I use GDINA package and when I Run GDINA(data, q) i have no problem, but when I run modelfit function I encounter this problem. You can see my data in the below link

This seems like a different question to the one above. To echo AlexisW, we don't have enough information to help you more than the info given in the error message.

The Gold-Standard method to present your problem problem in a way others can reproduce and start diagnosing it is with a reproducible example. I'd encourage mocking one up in a reply.

The error message missing value where TRUE/FALSE needed is telling you that a function is expecting a logical vector (ie one that have only TRUE or FALSE values), but the function was supplied with something else, I think an NA or NULL. Again, a reproducible example would be handy to diagnose the issue and as a starting point to start suggesting solutions.
