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))

p <- ggplot(df.allfreq, aes(x=ref.date, y = price.adjusted)) + 
  geom_point() + geom_line() + facet_grid(freq ~ ticker)

print(p)
