fmp_api_key: Install a Financial Modeling Prep API Key in Your '.Renviron'...
In jpiburn/fmpapi: Access to the Financial Modeling Prep Financial Data API

This function will add your FMP API key to your .Renviron file so it can be called securely without being stored in your code. After you have installed your key, it can be called any time by typing Sys.getenv('FMP_API_KEY').

1	fmp_api_key(key, install = TRUE, overwrite = FALSE, fmpcloud_access = FALSE)

`key`	`character`. The API key acquired from 'https://financialmodelingprep.com/developer/docs/pricing/'
`install`	`logical`. If `TRUE`, will install the key in your `.Renviron` file for use in future sessions. If `FALSE`, key is only loaded for the current R session and will not persist when a new session is loaded. This is potentially useful if you wish to access the API from a non-personal computer. Default is `TRUE`.
`overwrite`	`logical`. If `TRUE`, overwrite any existing FMP_API_KEY that you already have in your `.Renviron` file.
`fmpcloud_access`	logical. Is this key additionally activated on the 'fmpcloud.io' server? default is `FALSE`
