tq_get() get = "financials" now returns a warning and NA as Google Finance no longer provides data. We are actively looking for alternative data sources.
tq_get() get = "stock.prices.google" now returns a warning and NA as Google Finance no longer provides data. Use get = "stock.prices" instead to use Yahoo Finance, or use the riingo package to download from Tiingo.
Catch duplicate names in col_rename when you are renaming more than 1 column. Duplicate names are not allowed and return an error.
Fix duplicate name collision issue when the original name already includes a .. Duplicate names now get a ..1, ..2, etc. as opposed to .1, .2.

These include various current data such as Ask, Bid, Day’s High, Day’s Low, Last Trade Price, current P/E Ratio, EPS, Current Market Cap, EPS Projected Current Year, EPS Projected Next Year and many more.

The same seven moving averages are compatible with the geom.coord_x_date and coord_x_datetime) were added to enable zooming into chart sections using dates with no out-of-bounds data loss (e.g. out-of-bounds data loss with the scale_x_ functions).tq_get can now accept character vectors and data frames for the x arg, in addition to a single character input. This streamlines the getting of data for multiple inputs (e.g. stock symbols, stock indexes, etc).col_rename arg to tq_mutate and tq_transform, which enables fast and easy renaming during the operation.dplyr::group_by() with tq_mutate() and tq_transform(). The transform and mutate functions now work properly with grouped data frames.tq_get(), get = "key.ratios", where key ratios for stocks from the NYSE returned NA.x_fun, .x, and .y in the respective transform and mutate functions.get = "key.ratios" option for tq_get(), which retrieves 10-years of key performance ratios (89 total) from www.morningstar.com.
