Load Data from csv File

Downloads Symbols to specified env from local comma seperated file. This method is not to be called directly, instead a call to getSymbols(Symbols,src='csv') will in turn call this method. It is documented for the sole purpose of highlighting the arguments accepted, and to serve as a guide to creating additional getSymbols ‘methods’.

Usage

getSymbols.csv(Symbols,
                 env,
                 dir="",
                 return.class = "xts",
                 extension="csv",
                 col.names=c("Open","High","Low","Close","Volume","Adjusted"),
                  ...)

Arguments

Symbols: a character vector specifying the names of each symbol to be loaded
env: where to create objects. (.GlobalEnv)
dir: directory of csv file
return.class: class of returned object
extension: extension of csv file
col.names: data column names
...: additional parameters

Details

Meant to be called internally by getSymbols (see also).

One of a few currently defined methods for loading data for use with quantmod. Essentially a simple wrapper to the underlying R read.csv.

Value

A call to getSymbols.csv will load into the specified environment one object for each Symbol specified, with class defined by return.class. Presently this may be ts, zoo, xts, or timeSeries.

Note

This has yet to be tested on a windows platform. It should work though file seperators may be an issue.

You may need to set the format argument in the call if the date is not in a standard format in your file. For example format = "%m/%d/%Y". See strptime for format parameters.

Examples

if (FALSE) { # \dontrun{
# All 3 getSymbols calls return the same
# MSFT to the global environment
# The last example is what NOT to do!

## Method #1
getSymbols('MSFT',src='csv')


## Method #2
setDefaults(getSymbols,src='csv')
  # OR
setSymbolLookup(MSFT='csv')

getSymbols('MSFT')

## Method #3
