saveSymbols.days: Save data to disk

In FinancialInstrument: Financial Instrument Modeling Infrastructure

Save data to disk

Description

Save data to disk the way that getSymbols.FI expects it to be saved.

Usage

saveSymbols.days(Symbols, base_dir = "", extension = "rda", env = .GlobalEnv)

saveSymbols.common(Symbols, base_dir = "", extension = "rda", env = .GlobalEnv)

Arguments

Symbols	character vector of names of objects to be saved
base_dir	character. directory in which to store data.
extension	file extension (“rda”)
env	environment that holds the data to be saved (.GlobalEnv by default)

Details

If they do not already exist, subdirectories will be created for each of the Symbols. saveSymbols.common will save a single ‘rda’ file for each of the Symbols in that symbol's subdirectory. saveSymbols.days will split the data up into days and save a separate ‘rda’ file for each day in that symbol's subdirectory.

Value

called for side-effect.

      "SPY",
      base_dir = example_dir,
      env = example_env
