Subject: Re: GTR ETFs, etc?
Excellent suggestion! I use quantmod functions for other analysis - dont know why this slipped my mind.

I use Yahoo! sparingly - but its currently the ONLY free source for Russell ( the actual index - if you have historical data stored you can use IWM as a proxy)

Here's the code :

#install.packages("tidyquant") I commented it out - you will need to install if you dont have it already

library(tidyquant)
symbol="^RUT"
df <- tq_get(symbol, get = "stock.prices", from = "1980-01-01")
