[ACCEPTED]-How to get R to recognize your working directory as its working directory?-working-directory

You should copy shortcut to R (R.lnk file) to 14 desire folder. Then in "Properties" (right 13 mouse button -> last option) delete anything 12 in field "Start in..." in second 11 tab ("Shortcut"?). If you start 10 R with this shortcut working directory will 9 be that one where the shortcut is.

I don't 8 have english version of Windows so I'm not 7 sure about field names, but they should 6 be easy to find.

Similar questions were in 5 R-windows-faq:

2.5 How do I run it?

2.10 How can I keep workspaces for different projects in different directories?

2.14 What are HOME and working directories?

In 2.14 is mentioned that 4

The working directory is the directory from 3 which Rgui or Rterm was launched, unless 2 a shortcut was used when it is given by 1 the `Start in' field of the shortcut's properties.

You could use an environmental variable. This 4 can work with Sys.getenv() and Sys.setenv(). For instance:

> Sys.setenv(R_TEST="testit")
> Sys.getenv("R_TEST")
  R_TEST 
"testit" 

If you 3 sent the variable in your script, you should 2 be able to access it from within, and then 1 call setwd() on that output.

Save your workspace to the desired directory 2 and thereafter you just open the workspace 1 from Windows explorer.

I put the following line in front of my 10 scripts and it allows me to work across 9 my computers.

setwd(path.expand("~/path/to/working/directory/") )

where ~ is = to your home 8 directory.

Sys.setenv(HOME = "path") or Sys.setenv(R_USER = "path") can both set the home directory.

In 7 my case, I work on several windows boxes, each 6 have fairly different directory structures, but 5 by setting the home directory properly I 4 can sync code between computers and have 3 them run properly on each one since where 2 I run my R projects have similar directory 1 structures.

If you're using Emacs/ESS, this isn't a 8 problem. I navigate to the directory where 7 my R script is located, open it, then start 6 an R ESS process. An R console pops up 5 with the current directory as R's working 4 directory.

If you haven't converted to Emacs/ESS, I 3 recommend it. (Though to prevent a flame 2 war, I also note there are similar options 1 for Vi users.)

Hope that helps.

Just a detail: instead of reversing the 4 slashes as you say, just add another backslash. Two 3 of these \\ works the same way as one of 2 these /. That makes it at least a little 1 easier.

For Ubuntu:
Insert the following command 8 into your .Rprofile file (usually in your home directory):

setwd(Sys.getenv("PWD"))

Now 7 your default working directory will be whatever 6 directory you launched R from. Keep in 5 mind you can also set up default workspaces 4 in different directories by saving your 3 workspace image as .RData wherever you plan to 2 launch R (startup sources .Rprofile before searching 1 for .Rdata in the cwd).

To set the R work directory like the current 4 directory of the R script that I'm working, I 3 always use a combination of the commands 2 getwd() and setwd(), like this:

path <- getwd() setwd(path)

or

setwd(getwd())

To set working directory in R Studio: Refer detailed slide deck with screen-shots 8 here.

1. Using setwd(): windows users would need to replace backward slashes '' with forward slashes '/' or double backward slashes '\' You can do the former using find & replace (Short-cut: Ctrl+F)
2. Another option: Go to Session --> set working directory --> choose working directory & browse the folder which you want to set as the working directory, click on open
3. Quickest method (my favorite) use the shortcut 'Ctr+Shift+H' (on windows system), browse the folder which you want to set as the working directory, click on open

To set a permanent working directory (when not in a project) in R Studio: Refer my quick video on the same: https://youtu.be/hMjzO4bAi70

Go to 7 Tools --> Global Options --> R General 6 [Basic] --> Default Working Directory 5 (when not in a project) browse the folder 4 which you want to set as the working directory, click 3 on 'Apply' and 'OK'

However, the efficient 2 & better way to organize your work is 1 to create projects & use version control.
