If you are using the code from the previous tutorial, be careful as you need to consider the portfolio prices and not the returns. I was using portfolio returns which gave me the error of "ROI". Using portfolio prices fixed it.
what should I do? It doesn't work either. Error in optimize.portfolio(portfolioReturns, portf, optimize_method = "ROI", : ROI only solves mean, var/StdDev, HHI, or sample ETL/ES/CVaR type business objectives, choose a different optimize_method. Having this result, even if I had those ROI packages.
great tutorials, thank you. Part 2 worked well. but I have the same issue with "portfolio.spec" as others with Part 3. and i thought "R" was the answer for CAPM solutions. There are "R" online references to "portfolio.spec" (undated) but seems it may have been superseded and/or deleted with no reference to any replacement. that's a shame.
Getting this Error ---------Error in gmv_opt(R = R, constraints = constraints, moments = moments, : "package:ROI" %in% search() || requireNamespace("ROI", quietly = TRUE) is not TRUE-----------------I have installed ROI package as well...But it didn't work... can someone help.

ROI is a type solver that is available as an external package. With some downloads, it's already bundled in. Install the following packages using the install.packages("") command: ROI ROI.plugin.quadprog ROI.plugin.glpk Then load them like this: library(ROI) library(ROI.plugin.quadprog) library(ROI.plugin.glpk) You should be good after that...by the way if you want to do your own quadratic programming to get to your desired optimization then you should install.packages("quadprog"). There are other solvers available as well that you can use in the optimization. Here's a list from the PortfolioAnalytics doc: c("DEoptim", "random", "ROI", "ROI_old", "pso", "GenSA") You'll probably have to install the external libraries for some of these also. Hope this helps!

How do you do this when rf is not 0? I can change it on the efficient fronter plot, but I would like to do it on the optimize.portfolio function too
when rf is not 0, the the capital market line(tangential line) is not tangential. portfolio returns are lower than the risk free return
