portfolio.spec() function doesn't appear

[Prodromos23]

Error in portfoliospec() : could not find function "portfoliospec"

I install the package I call it from the library but the specific function doesn't appear at all inside the package.
Does anybody has an idea?

Are you sure you are looking at the right package? I use your function, but it's inside fPortfolio, by Rmetrics: fPortfolio::portfolioSpec(). Is this what you are looking for?
many thanks, thomas

the portfolio.spec function is part of PortfolioAnalytics.

fPortfolio is no longer actively maintained after the tragic death of Diethelm Wurtz,, so I wouldn't recommend fPortfolio or any of the RMetrics packages at this time.

exactly! and still cannot find it inside the package..

?PortfolioAnalytics::portfolio.spec

library(PortfolioAnalytics)

View(portfolio.spec)

thank you. There was a misspell. Do you want to delete the thread? I am kind of new in the github so I am not really sure if I can delete it.

True - absolutely terrible. A car accident in Hungary if I remember, together with his wife too, i think, in the summer, if i am not mistaken. This said - the package was very well written imho (some parts a little obscure though, but I managed to get it to "work", e.g. using custom inputs) - so it's not like its content really needs update if you're just after more or less vanilla mean-variance. What was built works fine - I checked it thoroughly.
If you have recommendations to switch though - i'd be all ears.
many thanks thomas
