I have problems with R package getReturns. I have encountered this error since 17th May:
Warning in file(file, "rt") : cannot open URL 'http://ichart.finance.yahoo.com/table.csv?s=AAPL&a=4&b=28&c=2014&d=4&e=27&f=2017&g=w&ignore=.csv': HTTP status was '404 Not Found'
It looks like that ichart API did not run anymore. Can anyone help me with this issue? Does someone know how to fix it? I have encountered the same issue with the quantmod R package.
You can follow my an earlier post, which might help you.
I tried :
library(quantmod)
# Create an object containing the Pfizer ticker symbol
symbol <- "PFE"
# Use getSymbols to import the data
getSymbols(symbol, src="yahoo", auto.assign=T)
# because src='google' throws error, yahoo was used, and even that is down
When I tried other source, it worked:
# "quantmod::oanda.currencies" contains a list of currencies provided by Oanda.com
currency_pair <- "GBP/CAD"
# Load British Pound to Canadian Dollar exchange rate data
getSymbols(currency_pair, src="oanda")
str(GBPCAD)
It seems there are issues with google and yahoo while we use quantmod pkg.
I will suggest you to use 'Quandl' instead. Plz goto Quandl website, register for free and create API key, and then copy it in below:
# Install Quandl
install.packages("Quandl")
# or from github
install.packages("devtools")
library(devtools)
install_github("quandl/quandl-r")
# Load the Quandl package
library(Quandl)
# use API for full access
Quandl.api_key("xxxxxx")
# Download APPLE stock data
mydata = Quandl::Quandl.datatable("ZACKS/FC", ticker="AAPL")
For HDFC at BSE, you can use:
hdfc = Quandl("BSE/BOM500180")
