A small demo of the things you can do using the quantmod package in R. For almost all the examples I will use the Google stock symbol GOOG

library(quantmod)
## Loading required package: Defaults
## Loading required package: xts
## Loading required package: zoo
## 
## Attaching package: 'zoo'
## 
## The following objects are masked from 'package:base':
## 
##     as.Date, as.Date.numeric
## 
## Loading required package: TTR
## Version 0.4-0 included new data defaults. See ?getSymbols.
sym <- "GOOG" #Change this to generate the same report for another symbol

You can pull company financial statements directly from Google finance using the getFinancials. This will pull the past 4 years of Google financial statements

financials <- getFinancials(sym, auto.assign=F)

For example, the yearly Balance Sheets for the past 4 years from Google

Ok thats cool. What else can you do?

Well… how about pulling stock quotes on a particular symbol?

options("getSymbols.warning4.0"=FALSE)
prc <- getSymbols(sym, auto.assign=F, src="google")

Here are a snippet the daily High, Low, and Open and Close prices for Google for the past 7 years

What else? Maybe you’re interested in trading commodities, in particual, you really, really like trading metals. Well, getting the prices of metals is easy! Let’s say you wanted to look at Gold and Silver prices from the past 100 days

gld <- getMetals("GOLD", from=Sys.Date()-100, to=Sys.Date(), base.currency="CAD", auto.assign=F)
slv <- getMetals("SILVER", from=Sys.Date()-100, to=Sys.Date(), base.currency="CAD", auto.assign=F)
print(cbind(gld, slv))
