downloadCMBPS(link = 1, destfile, save = TRUE)
link |
The link code (an integer from 1 to 6) for the URL to download the file. See code details in this help file. |
destfile |
A character string with the file name for the downloaded file to be saved. Tilde-expansion is performed. |
save |
A boolean indicating whether to save or not (since the downloaded data is returned anyway). |
