Download a File Gracefully with Retry Mechanism

Description

Attempts to download a file from a specified URL, retrying a set number of times if the download fails. This function meets CRAN's requirement for gracefully handling the use of internet resources by catching errors and returning a warning message if the download ultimately fails.

Usage

graceful_download(url, destfile, retries = 3)

Arguments

`url`	Character. The URL of the file to download.
`destfile`	Character. The path to the destination file where the downloaded content will be saved.
`retries`	Integer. The maximum number of download attempts (default is 3).

Value

Logical. Returns 'TRUE' if the download succeeds, 'FALSE' otherwise.

Examples

## Not run: 
dataset_url <- "https://example.com/dataset.csv"
tmp <- tempfile(fileext = ".csv")
success <- download_file_gracefully(dataset_url, tmp)
if (!success) {
  message("Continuing gracefully without the dataset.")
}

## End(Not run)
