Hi,

I have been trying to plot the efficient frontier using frontierMarkowitz in
fPortfolio:

front <- frontierMarkowitz(returns, targetReturn=mean(returns),Rf=0.00403
,doplot=T,length=300,r.range=NULL,s.range=NULL,which="all")

Using summary(front) I get the numerical values of the efficient frontier,
but I also get the error message
Error in plot.fPFOLIO(object, ...) : could not find function
"interactivePlot"
I cannot get the plots.

It seems that somethins small but important must be missing. Any ideas?

Thanks in advance,
Hannu
