To use smapr, users need to provide NASA Earthdata portal credentials. This function allows users to interactively set these credentials via the user's Earthdata username and password.

set_smap_credentials(username, password, save = TRUE,
  overwrite = FALSE)

Arguments

username

A character string of your Earthdata portal username

password

A character string of your Earthdata portal password

save

Logical: whether to save your credentials to your .Renviron file (e.g., ~/.Renviron). Previous Earthdata credentials will not be overwritten unless overwrite = TRUE.

overwrite

Logical: whether to overwrite previous Earthdata credentials in your .Renviron file (only applies when save = TRUE)

Value

A data.frame with the names of the data files, the remote directory, and the date.

Details

If you do not yet have a username and password, register for one here: https://urs.earthdata.nasa.gov/

A warning: do not commit your username and password to a public repository! This function is meant to be used interactively, and not embedded within a script that you would share.

Examples

if (FALSE) { set_smap_credentials('myusername', 'mypassword') }
