Correct one equality comparison by wrapping in all() to
ensure a length-one logical expression is created
The version comparison was corrected and the package no longer (formally) depends on R (>= 4.0.0)
Very minor README.md edits
The package now (formally) depends on R (>= 4.0.0) as it uses a recently added R function for the default config file.
A few URLs were updated in the README.md file
The time_series is now vectorised and can return a list
of return objects when given a vector of symbols
The use of tools::R_user_dir() is now conditional on
having R 4.0.0 or later, older versions can use env.var for api key
New helper function store_key to save api key.
New simple accessors get_quote and get_price
Initial version and CRAN upload
