Dear all,
I'm puzzled by the behaviour of path.expand("~")
In the RStudio IDE the output is> path.expand("~")
[1] "C:/Users/thierry_onkelinx/Documents"
In the R GUI the output is> path.expand("~")
[1] "~"
But I'm expecting the same result as in the RStudio IDE. The "Start
in"
parameter of shortcut to the R GUI has the value
"C:\Users\thierry_onkelinx\Documents"
The problem is that I use normalizePath("~/analysis"). This
yield "C:\\Users\\thierry_onkelinx\\Documents\\analysis" in RStudio
It throws an error in the R GUI
"C:\\Users\\thierry_onkelinx\\Documents\\~\\analysis"
Warning message:
In normalizePath(path.expand(path), winslash, mustWork) :
path[1]="~/analysis": Het systeem kan het opgegeven pad niet vinden

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to say
what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of data.

Hm. On my linux system:> path.expand("~")[1] "/home/sarahg" The help file says: Expand a path name, for example by replacing a leading tilde by the user's home directory (if defined on that platform). Does Windows 7 define ~? Just because RStudio defines it for you, doesn't mean that R shares that same setup; if R is checking with the operating system, then it depends on the Windows setup. You could, I assume, define ~ in Windows yourself, or write your own path.expand() to do so. I have no idea which option the RStudio designers took. Could you use getwd() to get the output you're looking for? I would expect ~ to properly be "C:/Users/thierry_onkelinx" and getwd() to be what you've set Start in as, suggesting that not only did RStudio define ~ for Windows, they did it in a non-standard way. (Unless your home directory on Windows should be Documents?)

(Unless your home directory on Windows > should be Documents?)The tilde meaning "home" is not a concept in Windows, but R fakes it. This is described in ?path.expand and the R for Windows FAQ. Thierry should set the R_USER environment variable to whatever home dir he wants. RStudio is probably doing that for him.

[1] "~"
Did you set the environment variable R_USER to something odd like "~"?

Dear Bill, The culprit was the environment variable HOME which was set to "~". Changing it to "C:/Users/thierry_onkelinx/Documents" solved the problem. Thanks for the hint. Best regards, ir.
