# (software) How can I use the latest version of R or RStudio??

The current installation on the HBS compute grid for RStudio is v0.99.99 and its companion R version is v3.1.2, the latest that this version of RStudio can fully support. We are aware that these are not recent versions: this is an unfortunate result due to limitations of the operating system (OS) and how software installations are managed on the compute grid. We are currently working with HBS IT find a solution to overcome this limation, which we hope to have remedied by late summer 2017.

In the meantime, if you require a more current version of R within this version of Read more about (software) How can I use the latest version of R or RStudio??

# (access) NoMachine NX is reporting "connection" or "access error" messages

Sorry to say, our NoMachine NX GUI login can be very particular at times. You may receive connection errors, access denied errors, or the like. A few simple steps may remedy the problem:

# (compute) Why are my jobs pending?

You may be reaching your user limits. Please see our page on use cases and user limits for details.

# (software) What if I need to use a new version of Python?

The Conda package manager makes it easy to install the latest and greatest Python and R packages in your home directory. For instructions, please see our Python, R, Packages, and the Grid page

# (storage) I need to restore a file in my home folder/project space from backup. How do I do this?

If you accidentally deleted a file, wrote over code, or have to restore a file, please email RCS with the following information:

• Full path of the file’s location
• File name
• Date file was deleted (if you do not know the exact date, a best guess is helpful)

# (storage) I think I've run out of space in my home/project directory. What can I do?

We urge individuals to review files and folders to remove old, unused, or temporary work. As a part of this process, you can compress and archive groups of files. See our HOWTO document for this. If space is still needed, contact RCS to request more space.

# (storage) Why do file permissions change when files are copied to research storage home folders and/or project spaces?

File transfer programs, including the Mac Finder and Windows Explorer, try to do  the best job possible matching permission when files are copies over. But since the operating systems typically are different between the source (your computer) and the destination (the storage on the compute grid), the programs attempt to match as best as possible. Of course, they often don't get it right. Please see our HOWTO document on Changing File Permissions.

# (storage) I'm getting 'permission denied' when trying to view files. What does this mean?

Unix systems rely on three set of permission for viewing and writing files. If these are not set correctly, you will see the dreaded 'permission denied' error. Please see our HOWTO document on Changing File Permissions.

# (compute) How can I tell whether my batch job is still running?

You can check for running jobs by using the bjobs command (details here) or by viewing the listing in the ‘Jobs’ window in PAC.

Open a terminal session and type bjobs on the command line (details here). Read more about (compute) I launched an application in NoMachine or the terminal. Why isn't it running?
