quantmod error in getSymbols(): download failed, HTTP error 404

[Adrian]

I am trying to use the quantmod package. I do not understand how to fix this error. I am new to R and i feel like i've just hit a wall for 3 days. Please help Ive put my code below.

df <- data.frame()

install.packages("quantmod")
library(quantmod)


df<- data.frame(getSymbols("APPL",auto.assign = F))

This is the console output:

Warning: APPL download failed; trying again.
Error in getSymbols.yahoo(Symbols = "APPL", env = <environment>, verbose = FALSE,  : 
  Unable to import “APPL”.
APPL download failed after two attempts. Error message:
HTTP error 404.

"APPL" symbol doesn't exist, maybe you are making a typo and you mean "AAPL"

This works

library(quantmod)

df <- data.frame(getSymbols("AAPL", auto.assign = FALSE))

head(df)

Hi, Adrian, and welcome

The ticker symbol for Apple is AAPL, not APPL.

The last line "HTTP error 404" indicates that 1) the API successfully connected to Yahoo, but 2) Yahoo had no page for APPL

In cases like this, where you find yourself repeatedly getting the same error, it's a good idea to test with other arguments to the function, such as "GE" to see whether the error affects all arguments or only the one you are using. Then, check your argument (no matter how confident you might feel!) and you'll usually find an error like the one you ran into.

Good luck!
