>Dear Prof. Wuertz:
>
>I have been reading "Statistics and Finance: An Introduction" by Dr.
>David Ruppert. The R code for this book was developed by a team at
>Texas A&M University and they rely on your Rmetrics
>libraries. Their website for the R code
>is: http://www.stat.tamu.edu/~ljin/Finance/stat689-R.htm
>
>I am writing because I ran into a problem in running their R
>code. When I try to use the function "armaFit" I get an
>error. Here is the specific code and error:
>
> > fit_ar <- armaFit(formula = LogReturn ~ arima(1,0,0)) #AR (1)
>Error in eval(expr, envir, enclos) : object "package" not found
>
>I also noticed that the function was moved into a different library
>(fArma) instead of the library that the Texas A&M team used
>(fSeries). While I do not expect any reply to this message, I
>thought that you might refer this message to whoever is supporting
>this library for further investigation.
>
>Let me also thank you very sincerely for your Rmetrics package. I
>am enjoying learning and using it very much.

>Sincerely,
