Problem with PortfolioAnalytics

Sam H
Hi,

I have come across an issue in PortfolioAnalytics. It might be that my data
(downloaded from Yahoo Finance) simply has issues but I guess this should
not lead Portfolioanalytics to fail.

Error in max_sr_opt(R = R, constraints = constraints, moments = moments,  :
  Objective function failed with message
 Error in optimize(f = sharpe_obj_fun, R = R, constraints = constraints,  :
  'xmin' not less than 'xmax'

Is this the issue of POrtfolioAnalytics or ROI or is this the issue in my
data? What is the issue and how to solve it or create a workaround?

Below is reproducible code that shows the problem:
library(PortfolioAnalytics)
