Thanks,
Is there a way to transform this data in numeric data with r?

The issue has nothing to do with fPortfolio. You are not parsing your input file correctly, run:
indices
head(indices)
sapply(indices, class)
Notice that your variable types are not numeric, such that it is impossible to take an average of them. Additionally, it looks like you have some extraneous columns. Once you fix the input data (either in R or in whatever program you used to come up with the csv) try again.

Mr. Harlow,
Very sorry. And thanks for your attention, isn´t my intention be rude.> library(xts)> library(fPortfolio)> indices> Spec = portfolioSpec()> setTargetReturn(Spec) = mean(colMeans(indices))Error in base::colMeans(x, na.rm = na.rm, dims = dims, ...) :'x' must be numeric

Assunto: [R-SIG-Finance] OptimizationWalmir,In order for anyone to help you, please follow the posting guide (see link below). You need to put a reproducable example in your question and attaching .csv files is generally not necessary, so try to avoid it if possible. What did you try? Which specific function "didn't work"? Be specific.Bob
