Re: [R] mixing strings and numeric doubles in an array

If you do an 'str' on your boject, you will probably find that TICKER is a factor. This is probably not what you want. So when you create the dataframe 'stock', use the parameter 'stringsAsFactors=FALSE' to prevent the conversion to factors. In the mean time, you can do: stocks$TICKER <- as.cha
