-Working with R
+==== Working with R in the VRW ====
+The VRW has no Internet connection, so a VRW user is not able to install R packages from the regular repositories. There are two possibilities to install R packages in the VRW:
+  - There is a trusted mirror of the CRAN that get's updated daily and is available on the VRW. The path to the mirror must be set by the user: http://rep001.research.usor.nl/
+  - Data managers of Researcher+ can upload data to the VRW. If you upload the package to the group drive (G:\) all members of the study can install that R package.
-R heeft een gekoppelde mirror voor packages. The path to the mirror must be set by the user: http://rep001.research.usor.nl/
+If you work often with the same packages or share the use of these packages, we advise you to put all the packages you need in a project folder on the Group drive.
-Researchers that need R are preferably assigned the role of Researcher+ Then they can upload the Weirdest R packages that are not on the CRAn mirror.
-Atlas.Ti
+=== Using GIT in R studio ===
-Since half of june 2024 VRW users for Atlas.Ti need an OEP- / p-account to use the application.
-External members of VRW’s need to be added to a special group to use UG specific licensed application like Stata of SPSS. Met externe leden van een RUG-studie voegen we de studie toe ipv te rommelen met een groep vol met alleen externen
+If you would like to use GIT in the VRW for version control, you can add GIT to the options of R studio.
-Wijzigingen in het aanvraagformulier: 1) in Iris via Topdesk, FA <topdesk@rug.nl> en ook via Formdesk (toegang via Antje de jong)
+Open R Studio and choose Tools | Global Options | GIT/SVN. The local path to Git is "C:/Program Files/Git2251/cmd/git.exe"
-De rol van Researcher Plus en Datamanager interfereren. Als iemand download rechten behoeft dan deze Datamanager maken.
-Ralf Pelster can assign applications to VRW users
+==== Atlas.Ti in the VRW ====
-The request to limit folders in the Group drive to certain users is not very welcome. That does not promote the ease of management. It is better to assign Controller rights to the PI so he can write data to I:\. You can request this from Storage en AD
+VRW users for Atlas.Ti need to log in to Atlas.Ti. Researchers from the UG can use their personnel number (p-account), and external researchers can log in with their institutional account if the institution has a license for Atlas.Ti.
-Folders in the Group drive of the VRW can have limited rights for some users. This can be asked for in a Topdesk call to Storage and AD (active Directory)
+During the VRW intake consultation we will discuss the applications needed for the study. If Atlas.Ti is deemed necessary, the VRW consultant can arrange for an OEP account for external researchers. An OEP account is an account for external personnel of the UG.
-Access could not be granted:  New user accounts need to wait some 4 hours for the script for a home drive to run. After that period they should have a workstation.
-A mobile number is necessary only an E-mail address is not enough. The error will be that “This account does not exist”
+==== Problems with the Citrix client or starting up the VRW ====
+We have seen that the VRW could not start properly and gave an error "file has been moved". This is after authentication. We solved the error by de-installing the Citrix Client and installing the client anew. But - and this is essential - install it from the dfh.usor.nl portal. The Citrix client from this portal is pre-configured with VRW settings
