R help - Jan 2005 - evir package as.double problem

Dear Sirs,

I am working with a time series of financial data compiled in a csv file.

When i tried to apply the findthresh funtion of the evir package to that data I
got the following error messages (the second after transforming the list in a
vector):

"Error in as.double.default(x) : (list) object cannot be coerced to
double"

"Error in as.double.default(as.vector(port)) :
        (list) object cannot be coerced to double"


I hope ypu can help me with this problem.

Thanks,

Paulo Barbosa
