Question

Using quantmod and collecting data from Yahoo.
I am trying to get the dates that are in rownames.
However I am just getting NULL.

library("quantmod")
sp500 <- new.env()

getSymbols("^GSPC", env = sp500, src = "yahoo",
           from = as.Date("2008-01-04"),  to = Sys.Date())
GSPC <- get("GSPC", envir = sp500)
date1 <- rownames(GSPC)

date1
> NULL

I would be grateful for your help into getting the rowname dates into a vector.

You need to use the index function. The xts object isn’t the same as a normal data.frame, and has its own way of handling dimension names.

# Return all dates
index(GSPC)
