Hi @variable,
I couldn't get any downloads to work with startDate and endDate included in the arguments.
It worked fine without any date limits - you can easily fix your date selection later in R.
I also noted that some of the src= options don't work either.
library(quantmod)
startDate <- as.Date(2019-04-01)
endDate <- as.Date(2020-04-24)
getSymbols("SPY", from = startDate , to = endDate)
getSymbols("SPY", from = startDate , to = endDate, src = "yahoo")
getSymbols("SPY", from = startDate , to = endDate, src = "google")
getSymbols("SPY", from = startDate , to = endDate, src = "oanda")
getSymbols("SPY", from = startDate , to = endDate, src = "FRED")
getSymbols("SPY", src = "yahoo")
getSymbols("SPY")
dim(SPY)
head(SPY)
tail(SPY)
HTH
