# Install Packages on Spotfire Statistics Services

You can install packages onto the Spotfire Statistics Services server. If you want to use packages from a repository on the internet (such as CRAN), you need a computer with a connection to the internet.

Note: If you use this method in a cluster environment, you must upload the same package on each server in the cluster.

- If you have administrative privileges, then you can log on to the Spotfire Statistics Services server with administrative credentials, and then use the TERR function `install.packages` to upload packages from the repository. See Uploading a Package to Spotfire Statistics Services From a Repository for more information.
- If you have administrative privileges, then you can copy a package from an in-house computer to the Spotfire Statistics Services server. See Uploading a Package to Spotfire Statistics Services from Another Computer for more information.

After installing packages on Spotfire Statistics Services, you can validate the upload.

Note: If you are using TERR with Spotfire Statistics Services, be aware that by default, certain Spotfire Statistics Services capabilities are disabled. If you created or used functions in a previous release, or if you install packages that contain functions that TERR deems to be potentially malicious, you might find that they do not work as expected. Any expression that TERR determines to be potentially malicious is disabled. For more information, see the Spotfire Statistics Services User's Guide and talk to your server administrator.
