Results are confusing. Docs say in setDefaults(name...), name = name of function, quoted or unquoted. Here is what happens with AV.
setDefaults(getQuote.av, api.key='xxx')
# Error in setDefaults(getQuote.av, api.key = "xxx") : object 'getQuote.av' not found
setDefaults('quantmod:::getQuote.av', api.key='xxx')
# Error in get(fun, mode = "function", envir = envir) : object 'quantmod:::getQuote.av' of mode 'function' was not found
setDefaults('getQuote.av', api.key='xxx')
# works, huh
@helgasoft Can you help me understand how this relates to the initial report. It looks like a separate issue.
Maybe I entered the wrong room. Was searching for issues with getQuote and defaults ... Sorry, I don't really understand what 'import defaults' means.
Oh, that makes sense. I don't think this is related to the issue you uncovered, so I'd appreciate it if you create a new issue.
For some examples of what Ethan is referring to by "import defaults", you can search for "importDefaults" in getSymbols.R.
A bit more background: setDefaults()
and importDefaults()
basically let you set global options that are injected into the function call. It allows you to change the default value of an argument for all subsequent calls.
For example, you can set the default "from" date to 1 year ago. Then all your calls to getSymbols()
will use that date by default.
setDefaults("getSymbols.yahoo", from = Sys.Date() - 365)
getSymbols("SPY")
head(SPY)
