# Validating the Package Upload

After you upload a package, run a quick validation to ensure that your package is on the server.

## Before you begin

You must have administrative privileges to perform this task.

## About this task

Perform this task from the TERR console in your installation of Spotfire Statistics Services

## Procedure

1. From the browser, type the following command.
   `installed.packages()`
   A list of installed packages is printed in the console.
2. Review the list (including the path) to ensure that the package you uploaded is installed.
   Important: Although the package is on Spotfire Statistics Services, it is not loaded into the engine. With each call to Spotfire Statistics Services, the engine is started anew.

   To use the package, you can either load the library as part of your function scripts, or you can include it in the `Packages` field of your data function.
