For some reason, a code I usually run in Rstudios is no longer working. I'm hoping that someone has had a similar experience and understands what's going on.
getReturns(c('C','BAC'), start='2004-01-01', end='2008-12-31')
This results in:
Error in unclass(e1) + unclass(e2) :
non-numeric argument to binary operator
I can't find anything online nor on stackoverflow that addresses this issue. Also, I saw that the most recent documentation, from July 2014 doesn't mention anything either:
http://cran.r-project.org/web/packages/stockPortfolio/stockPortfolio.pdf
Does anyone have any idea what's going on here?
It's probably a function name clash issue. Running
timeSeries::getReturns(c('C','BAC'), start='2004-01-01', end='2008-12-31')
gives me the error, but running
stockPortfolio::getReturns(c('C','BAC'), start='2004-01-01', end='2008-12-31')
works fine.
How did this happen?
You must have loaded the stockPortfolio package, and then loaded either timeSeries or another package that depends upon timeSeries. Have a look through your console for a message that looks like
The following object is masked from ‘package:stockPortfolio’:
getReturns
Use the double colon operator (as shown above) to explicitly tell R which package to look in.
