This vignette shows detailed examples for all functionalities of the interactive_netrc() function.

1 Configuration

In order to connect to ImmuneSpace, you will need a .netrc file in your home directory that will contain a machine name (hostname of ImmuneSpace), and your ImmuneSpace login and password. See here for more information.

A netrc file may look like this:

machine datatools.immunespace.org
login myuser@domain.com
password supersecretpassword

2 Writing your netrc file

There are two options when it comes to writing a netrc:

If you’re familiar with the command-line interface, see the introductory vignette.
For those less comfortable with the command line, there is the interactive_netrc function.

2.1 interactive_netrc()

The interactive_netrc function will:

check if a netrc file already exists
prompt the user for login and password information in the R console
check that the provided login information allows the user to connect to ImmuneSpace
if the connection is valid, then write the information to a netrc file in the user’s home directory

Below is a gif demonstrating how to use this function:

In the case that the user did not provide login information that results in a connection to ImmuneSpace, a netrc file will not be written to the user’s home directory, and the user can try the method again checking for typos.

If the user still cannot connect to ImmuneSpace via the API, they might want to double check that they are registered and that their login information works for ImmuneSpace.

If a netrc file already exists, interactive_netrc will print the existing file to the console and ask the user if they wish to overwrite that file.

Y or y will result in the same process as if there were no netrc and overwrite the existing file.
N or n will simply check if the existing netrc is able to connect to ImmuneSpace. No new netrc file will be created.
