Once you find the data you'd like to load into R on Quandl, copy the Quandl code from the description box and past it into the function.
> data <- Quandl("NSE/OIL")
To extend your access to the Quandl API, use your authentication token. To do this sign into your account (or create one) and go to your account info page. Then copy your authentication token and type (with quotes):
This will then extend your usage.
Create a graph of the Nasdaq, with a monthly frequency
There are a few things you need to do before you can proceed with uploading data. * Make an account and set your authentication token within the package with the Quandl.auth() function. * Get your data into a data frame with the dates in the first column. * Pick a code for your dataset - only capital letters, numbers and underscores are acceptable.
Then call this function
Quandl.push(code="TEST", name="This is a test dataset", description="This description can include extra information about the time series including units",data=yourdataset)`
The function returns a link to your newly created dataset. When creating a dataset the fields code, name, and data are mandatory. When updating a dataset only the code is mandatory.
If you would like to update your dataset - change the name, add new data - pass update=TRUE to the function otherwise it will ask if you are sure.
Downloading a partial dataset and uploading it with code TEST.
Quandl.auth("enteryourauthenticationtoken") mydata = Quandl("NSE/OIL", rows=5) Quandl.push("TEST",name="This is a test dataset",description="This is a description",data=mydata)
Will return a link to your newly uploaded dataset
Searching Quandl from within the R console is now supported. An authorization token is not required, but for extended use specify your token using
Quandl.auth(). The search function is:
Quandl.search(query = "Search Term", page = n, source = "Specific source to search", silent = TRUE|FALSE)
Which returns a list containing the following information for every item returned by the search:
A search for Oil, searching only the National Stock Exchange of India (NSE).
Quandl.search("Oil", source = "NSE")
Oil India Limited Code: NSE/OIL Desc: Historical prices for Oil India Limited (OIL), (ISIN: INE274J01014), National Stock Exchange of India. Freq: daily Cols: Date|Open|High|Low|Last|Close|Total Trade Quantity|Turnover (Lacs) Crude Oil (petroleum) Price Code: IMF/POILAPSP_INDEX Desc: Crude Oil (petroleum), Price index, 2005 = 100, simple average of three spot prices; Dated Brent, West Texas Intermediate, and the Dubai Fateh Freq: monthly Cols: Date|Price China Crude Oil Consumption Code: INDEXMUNDI/ENERGY_CHINA_CRUDEOIL Desc: Energy production of Crude Oil in China.
