It could (through a "require" in the call to "setup()").
In theory, this is the same with rpy2. The import will not be made if
R_HOME is defined:
# --- from rpy/rinterface/__init__.py ---
if len(R_HOME) == 0:
if sys.platform == 'win32':
try:
import win32api
import win32con
hkey = win32api.RegOpenKeyEx(win32con.HKEY_LOCAL_MACHINE,
"Software\\R-core\\R",
0, win32con.KEY_QUERY_VALUE )
R_HOME = win32api.RegQueryValueEx(hkey, "InstallPath")[0]
win32api.RegCloseKey( hkey )
except:
raise RuntimeError(
"Unable to determine R version from the registery." +\
"Calling the command 'R RHOME' does not return
anything.\n" +\
"This might be because R.exe is nowhere in your Path.")
I will likely prefer wrapping the import statement in a try/except
provide a more self-explicit error message upon ImportError.
