I'd like to show you how to use R to get global stock prices.
it is freaking easy.
just enter following code to get S&P 500 index.
getSymbols('^GSPC', src='yahoo')
plot(GSPC)
It's too easy, isnt it?
If you trying to find out Nvida's stock price, then enter NVDA instead of ^GSPC.
nvda <- auto.assign="FALSE)</p" getsymbols="" src="yahoo">plot(nvda)
Sorted
*Additional information
Free financial data
1) R package quantmod
:yahoo(stock information) / google(stock data)
:FRED(economic indicators)
:Oanda(FX data)
example) Oanda
getSymbols("USD/EUR",src="oanda")
plot(USDEUR)
2) R package Quandl (not all free but some of them are free)
example) Quandl
Let's get oil price and draw a graph
install.packages("Quandl")
library(Quandl)data = Quandl("OPEC/ORB")
library(Quandl)data = Quandl("OPEC/ORB")
3) R package TFX which provides real time tick data
Sample)
install.packages("TFX")
QueryTrueFX()
yen <- span=""> ConnectTrueFX("USD/JPY,EUR/JPY,GBP/JPY,AUD/JPY,CAD/JPY,CHF/JPY",
username="ID", password="PW")
QueryTrueFX(yen)
QueryTrueFX()
yen <- span=""> ConnectTrueFX("USD/JPY,EUR/JPY,GBP/JPY,AUD/JPY,CAD/JPY,CHF/JPY",
username="ID", password="PW")
QueryTrueFX(yen)
4) R package pwt which provides global economic data
Sample)
install.packages("pwt8")
library("pwt8")
data("pwt8.0")
countries <- c="" div="">
variables <- c="" country="" div="" isocode="" nbsp="" pop="" rgdpo="" year="">
pwt <- countries="" in="" isocode="" pwt8.0="" select="variables)</div" subset="">
summary(pwt)
