How to interpret the name of an object literally?
..."fund" is a matrix of open, high, low, close, and volume prices
returns <- function(fund)
{
p_12ago = as.vector(fund[nrow(fund)-252,6])
perc_diff_12mo = ((p_last - p_12ago) / p_last)*100
#This is the line that's giving me problems:
funds=c(as.character(fund))
mo12=c(perc_diff_12mo)
final_results=data.frame(funds,mo12)
return(final_results)
}
I can't figure out how to insert the original argument from the function (in
this case the name of the fund).
Ultimately I want to be able to do returns("GOOG"), and have the output in
this for...
