[R-SIG-Mac] package.skeleton

        I have developed a R script that works perfectly. Since it is long and 
complicated, I want to create a R package and share it with my team members. 
With one exception of the function TrafficData, all functions of the package 
version of my script works fine.


> datasets = TrafficData()
Error in as.numeric(q) : 
  cannot coerce type 'builtin' to vector of type  double'

I have checked all functions of my script where `q` is called in TrafficData.' 
They all work fine. For example, TrafficData calls the functions K, phi.X. 
and qk. K is only one that requires q.

> K
function (q, x) 
{
    kjam = as.numeric(kjam)
    kstar = as.numeric(kstar)
    qstar = as.numeric(qstar)
    x = as.numeric(x)
    q = as.numeric(q)
    m = qstar/(kjam - kstar)
    kf = (kstar/qstar) * q
    kc = (m * kjam - q)/m
    if (x == 1) 
        k = kc
    else k = kf
    return(k)
}
<environment: namespace:traffic>
> K(3.2,1)
[1] 0.4207143

        As I was developing the script, I found that I needed as.numeric' 
command. I use it throughout the script. Removing q = as.numeric(q) from K 
gives the same Error message. 

        I am a novice with package.skeleton. I am unsure how to find the bug. 
Any suggestions will be greatly appreciated.

Thanks,
Paul

        To be thorough, I provide the following Warnings. I dont believe they 
are connected to the above Error. Suggestions for eliminating these warnings 
are also welcome. Incidentally, I did not provide an Example.
