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.
