R 4.2.3
OS X
Colleagues
Interesting (minor) problem. I have code that I run automatically on two
different computers. The code runs from Dropbox so there is not separate code
for each computer.
In order to identify which computer is running the code, I was hoping to do
something like:
Sys.getenv(SOMETHING)
In a terminal window:
echo $PS1
returns the prompt on that particular computer.
However, when I attempt to access that from R, I am not successful. For
example:
In a terminal:
echo $PS1
returns:
PET\!>
In R:
Sys.getenv("PS1")
returns:
""
In R:
system("echo $PS1")
returns an empty line.
A solution to this immediate problem (how to obtain that environment variable
in R) or any other clever way to identify a particular computer would be much
appreciated.
