One of the main requests I get for package BatchGetSymbols
is to add the choice of frequency of the financial dataset. Today I finally got some time to work on it. I just posted a new version of BatchGetSymbols in CRAN. The major change is that users can now set the time frequency of the financial data: dailly, weekly, monthly or yearly. Let’s check it out:
library(BatchGetSymbols) ## Loading required package: rvest ## Loading required package: xml2 ## Loading required package: dplyr ## ## Attaching package: 'dplyr' ## The following objects are masked from 'package:stats': ## ## filter, lag ## The following objects are masked from 'package:base': ## ## intersect, setdiff, setequal, union ## library(purrr) ## ## Attaching package: 'purrr' ## The following object is masked from 'package:rvest': ## ## pluck library(ggplot2) my.fct <- function(my.freq) { df <- BatchGetSymbols(tickers = c('GE'), first.date = '2010-01-01', last.date = Sys.Date(), do.cache = FALSE, freq.data = my.freq)$df.tickers df$freq <- my.freq return(df) } my.possible.freq <- c('daily', 'weekly', 'monthly', 'yearly') df.allfreq <- bind_rows(map(.x = my.possible.freq, .f = my.fct)) ## ## Running BatchGetSymbols for: ## tickers = GE ## Downloading data for benchmark ticker ## GE | yahoo (1|1) - Good stuff! ## Running BatchGetSymbols for: ## tickers = GE ## Downloading data for benchmark ticker ## GE | yahoo (1|1) - Good job! ## Running BatchGetSymbols for: ## tickers = GE ## Downloading data for benchmark ticker ## GE | yahoo (1|1) - You got it! ## Running BatchGetSymbols for: ## tickers = GE ## Downloading data for benchmark ticker ## GE | yahoo (1|1) - Feels good! p <- ggplot(df.allfreq, aes(x=ref.date, y = price.adjusted)) + geom_point() + geom_line() + facet_grid(freq ~ ticker) print(p)
