R help es - Feb 2025 - Código reproducible Error in while (diff > 1e-08) { : missing value where TRUE/FALSE needed

Estimados

Hace unos minutos envié una consulta, pero el código para reproducir el error
estaba sin los datos, yo los tenía en memoria y no me di cuenta, ahora envío el
el código con los datos, la función y la pregunta, todo reproducible.

Pregunta original : Error in while (diff > 1e-08) { : missing value where
TRUE/FALSE needed

Gracias Javier Marcuzzi

## Given the MME, iteratively solve for the solutions by Jocobi Over Relaxation.

## Arguments
## LHS: left hand side of MME
## RHS: right hand side of MME
## inits: a vecotr of initial values for the solutions
## w: a vector of relaxation factor
## disp: a logical value. If true, show the solutions at each iteration

## Note: When 'w' is all one, usual Jacobi method will be performed.
jor <-
  function(LHS, RHS, inits, w, disp) {
    D <- diag(diag(LHS))
    R <- LHS
    diag(R) <- 0
    w <- diag(w)
    Dinv <- solve(D) %*% w
    x <- matrix(inits)
    I <- diag(1, dim(w)[1])

    diff <- 1
    i <- 0
    while (diff > 10E-9) {
      i <- i + 1
      newx <- (I - w) %*% x + Dinv %*% (RHS - R %*% x)
      if (disp == TRUE) {
        cat("\n")
        cat("iteration ", i, "\n")
        print(x)
      }
      diff <- (sum((newx - x)^2)) / sum(newx^2)
      x <- newx
    }

    cat("\n")
    cat("Final solutions after", i, "th iteration")
    return(x)
