Fetching collections of prices

Collections are just a bundle of tickers pre-organized in the package. For example, collection SP500 represents the current composition of the SP500 index.

The available collections are:

available_collections <- yfR::yf_get_available_collections(
  print_description = TRUE
  )

## Error in get(paste0(generic, ".", class), envir = get_method_env()) : 
##   object 'type_sum.accel' not found

## 

## ── Description of Available Collections ──

## 

## ℹ SP500: The SP500 index (US MARKET) - Ticker = ^GSPC

## ℹ IBOV: The Ibovespa index (BR MARKET) - Ticker = ^BVSP

## ℹ FTSE: The FTSE index (UK MARKET) - Ticker = ^FTSE

## ℹ DOW: The DOW index (US MARKET) - Ticker = ^DJI

## ℹ testthat-collection: A (small) testing index for testthat() -- dev stuff, dont use it!

available_collections

## [1] "SP500"               "IBOV"                "FTSE"               
## [4] "DOW"                 "testthat-collection"

One can download the composition of the collection with yf_collection_get:

library(yfR)

# be patient, it takes a while
df_yf <- yf_collection_get("SP500")

head(df_yf)
