Hi R Helpers, I recently tried to take advantage of the ability to download all the tickers in the S&P 500 using the functionality of tidyquant, but it threw an error. For summary, the set of commands that I ran was library(tidyquant) tq_index_options() tq_index("SP500") sessionInfo() R feedback including error message and sessionInfo are provided below. Guidance would be appreciated. --John J. Sparks, Ph.D. > library(...

I was able to reproduce the problem with this self-contained example. Maybe it could be reproduced with an even smaller one ... library(tidyquant) # Loads tidyverse, tidyquant, financial pkgs, xts/zoo library(xts) dtV <- as.Date("2017-01-01") + 1:100 locL <- list( foo=xts(rnorm(100), order.by=dtV), bar=xts(rnorm(100), order.by=dtV) ) fullXts <- do.call(merge,locL) smallXts <- fullXts["2017-02-01::"] rolling...

...panel showing the time series of historical prices of some stock, and the bottom panel showing the volume traded per day immediately below it. The common x-axis is the dates of the time period covered. I would like to create such a standard plot using ggplot2. How does one do it? The goals of the tidyquant package would seem to include the easy creation of such a chart, but I could not find this in tidyquant. Suppose it were possible to easily create such a chart in ggplot2 (or tidyquant which uses ggplot2.) Then with such data for numerous stocks (or other financial instruments) one could see a gri...

Could you provide some information on your data structure (e.g., are the two time series in separate columns in the data)? The solution is fairly straightforward once you have the data in the right structure. And I do not think tidyquant is necessary for what you want.

Buenas Os queria preguntar que ventaja le veis a las tibbles frente a los data.table, ya que para mi, quitando el uso de librerias como tidyr o purrr, en el resto prefiero usar data.table. Me parece igual de potente y mucho más rápido, y no le veo las supuestas ventajas, pero quiero conocer vuestra opinion. Gracias Jesús [[alternative HTML version deleted]]

....table es un tanto compleja frente a la sencillez que ofrece el trabajar con pipelines y para conjuntos medianos, no hay tanta diferencia en rendimiento. Por otro lado, son cada vez más los paquetes que se quieren hacer compatibles con este esquema "tidyverse" ("tidytext", "tidyquant", hasta el mismo "sparklyr").
