Problem plotting results in fportfolio
If you have received a reply to this question? I haven't seen one. If you would still like help from this listserve, I suggest you PLEASE do read the posting guide! "www.R-project.org/posting-guide.html" and follow the suggestions there. In particular, if you provide a small, self-contained example that someone like me can copy from your email into R and get the error message you got. Where can I get the "fportfolio" you mention? You may or may not know that R is case sensitive. Thinking you might be referring to the "fPortfolio" package, I installed that and looked for a function called "markowitzporfpolio". After finding "no documentation" found for "markowitzporfpolio", I tried, 'help(package="fPortfolio")'. This identified "MarkowitzPortfolio" as a key word. The help file for that name contains several examples. However, I am now out of time for this and must attend to other tasks. If you would still like help from this group, please submit another post. However, before you do, please read the posting guide mentioned above and proofread your email before you hit "send". If you do that, it might increase the chances of receiving a useful reply quickly. spencer graves

Hello,
I'm trying to use the package fportfolio and I'm experiencing few problems.
The first was related with the pfolio function, which seems to have a bug
and I solved it using a new funcion posted oved the internet. (the function
sets pfolio to null).ok I worked out this first issue.
When I tried to execute the example of the markowitzporfpolio I was able to
get the weights, however the plots are not working and I got this message:
Error in xy.coords(x, y, xlabel, ylabel, log) :
'x' and 'y' lengths differ
Is there anybody whom got the same problem?
Thanks
Namir
