 ### Home directory
-When you log in either via https or ssh this is usually the first place where you end up. Your home directory can be abbreviated by "~/". There is not a lot of space here, so do not place any larger data here. RStudio has the ugly not configurable habit to write quite some temporary data here (e.g. cached plots and suspended sessions), so please make sure that you clean up occasionally. It is a good place for your scripts.

-RStudio stores several files like suspended sessions, graph history etc. in `~/.rstudio`. This folder is purged every 90 days to remove "forgotten" suspended sessions and reduce wasted space. R itself stores workspace objects in `.RData` of your current working directory if you end your session or call `save.image()` without further arguments. Please ensure that you do not save large `.RData` files in your home directory.

 ### /data
-You can create your own directories here and place data inside. By default others can read the directories you created here, but not write in them. If you need any special permission let us know via it-support@idiv.de. To directly jump to another directory select the *Files* pane and click on the three dots (…) located on the right hand side of the current file path. Now enter the path you want to browse, e.g. `/data/`. Additionally there should be a symbolic link in your home directory called data, which points to the /data directory.

If you have any longer running jobs you might want to consider either moving stuff from the ~/winhome to /data or open a [tmux](tmux.md) session from which you detach (Ctrl+b, d) before you disconnect.

 ## R and data
 ### compression
 
-Please note that R is able to work with compressed files. This is especially useful if you are the typical csv/txt file user. Those files usually contain highly redundant data. Therefore compression can be very effective, e.g. the file which triggered me to write this was a txt file of 4 GB the gz compressed file had 98 MB. Many tools to read or write (e.g. save, save.image, read.table, fread from data.table) allow transparent use of compressed files, i.e. you just specify the compressed file instead of the uncompressed file.

 ## Data transfer
 You can use either use the web IDE to upload and export files.
 
 ### Web IDE
-In the *Files* pane click the *Upload* button to upload files to the current directory. For multiple files check the displayed *TIP* in the upload window. For big files please see below.

 ### Tools
-Other file transfer tools are often more reliable and faster than the web IDE. Short instructions are available for several tools like [scp](scp.md), [rsync](rsync.md), [filezilla](filezilla.md).

 ## Code organisation
 
-It is strongly recommended to use the version control system [git](https://git-scm.com) to track changes in your code. It also helps you to distribute your code, be it for yourself  (local machine, rstudio server, HPC cluster, …) or with others (e.g. via [github](https://github.com) or the [iDiv gitlab](https://git.idiv.de)). Ensure that you only track your code and not your data or results!

-If you want your code to run in differenct environments (e.g. local machine, rstudio server or HPC cluster) be sure to separate environment specific code from your buisness logic. Recommendations and templates can be found in the [EVE HPC Cluster wiki](https://wiki.ufz.de/eve/index.php/R_Advanced_-_Tips_%26_Tricks#Interactive_and_Command_Line).

 ## Packages
-Many R packages are installed already via the system's package management and many more are available via the same track. This is the preferred way to install R packages, as it avoids duplicate installations per user, removes the need for manual package updates and helps that underlying libraries and packages are compatible with each other. Currently there are >3500 packages installed—check with `installed.packages()` for more details.
-
-Of course you can still install packages via R's own functions (install.packages, devtools, …) if there is the need for it. Long term please drop a note to it-suppot@idiv.de so that we can install the package via the system.

 ## Other servers with R
-There are some other servers which have R and RStudio (desktop version) installed, but support for R on those is limited. This means you might frequently encounter outdated versions of R and associated packages.
