Question: I created a folder in order for it to be the main work directory meaning all the files I create go there, and files I read will be from there.
For some reason after I created the folder and I'm trying to set it as the working directory I get this message:

```
Error in setwd("~/") : cannot change working directory  

```

When I try to create files they are saved somewhere different and I get an error when trying to load them. I used the `scan` function and got:

```
Error in file(file, "r") : cannot open the connection

```

In addition: Warning message:

```
In file(file, "r") : cannot open file 'ff': No such file or directory

```

Answer: 
The command `setwd("~/")` should set your working directory to your home directory. You might be experiencing problems because the OS you are using does not recognise `"~/"` as your home directory: this might be because of the OS, or it might be because of not having set that as your home directory elsewhere.

As you have tagged the post using RStudio:

* In the bottom right window move the tab over to 'files'.
* Navigate through there to whichever folder you were planning to use as your working directory.
* Under 'more' click 'set as working directory'

You will now have set the folder as your working directory. Use the command `getwd()` to get the working directory as it is now set, and save that as a variable string at the top of your script. Then use `setwd` with that string as the argument, so that each time you run the script you use the same directory.

For example at the top of my script I would have:

```
work_dir <- "C:/Users/john.smith/Documents"
setwd(work_dir)

```
Maybe it is the case that you have your path in couple of lines, you used enter to make it? If so, then part of you paths might look like that "/\nData/" instead of "/Data/", which causes the problem. Just set it to be in one line and issue is solved!
