[R] Error in dimnames in R

[PIKAL Petr]

Hi

Without knowing much about the functions you use I would suggest few hints.

Do not use HTML format, your message could be scrambled.
Does frontier conform to data expected by function tailoredFrontierPlot?
Your best option could be to contact directly the maintainer. You could get his address by

maintainer("fPortfolio")

Instead of your whole code you should post the minimum reproducible example, with data preferably copied from

dput(frontier)

directly to your mail.

Cheers
Petr
