complete_cases

Removes symbols that return an NA value due to an error with the get call such as sending an incorrect symbol "XYZ" to get = "stock.prices". This is useful in scaling so user does not need to add an extra step to remove these rows. TRUE by default, and a warning message is generated for any rows removed.

• from: Standardized for time series functions in quantmod, quandl, tiingo, alphavantager packages. A character string representing a start date in YYYY-MM-DD format.

• to: Standardized for time series functions in quantmod, quandl, tiingo, alphavantager packages. A character string representing a end date in YYYY-MM-DD format.

Details

tq_get() is a consolidated function that gets data from various web sources. The function is a wrapper for several quantmod functions, Quandl functions, and also gets data from websources unavailable in other packages. The results are always returned as a tibble. The advantages are (1) only one function is needed for all data sources and (2) the function can be seamlessly used with the tidyverse: purrr, tidyr, and dplyr verbs.

tq_get_options() returns a list of valid get options you can choose from.

tq_get_stock_index_options() Is deprecated and will be removed in the next version. Please use tq_index_options() instead.
