Yes, this file exists and when I launch it, a new functionally-working R terminal window pops up. > I'm suspecting that Rcmd.exe somehow messes up when it tries to locate > Rterm.exe to launch it. Here's one way to see what happens: > > 1. Download Sysinternals Process Monitor, a free monitoring utility, > from the Microsoft website and launch it (no installation needed): > https://learn.microsoft.com/en-us/sysinternals/downloads/procmon > > 2.

Run tools::Rcmd('SHLIB --help') (or any other Rcmd invocation that > fails to produce any output for you) > > 4. You should get one event of Rcmd.exe trying to launch cmd.exe with a > long command line. What is the command line? For 2., I also added the Process name "Rterm.exe" Here are the outputs from Process Monitor for each situation. In the first situation, I run the command tools::Rcmd('SHLIB --help') from within R (launched by clicking on the R icon). I get: Process Name: Rcmd.exe PID: 8204 Path: C:\WINDOWS\System32\Conhost.exe Result: SUCCESS Detail: PID: 4028, Command line: \??\C:\WINDOWS\system32\conhost.exe 0xffffffff -ForceV1 In the second situation, I run the command tools::Rcmd('SHLIB --help') from the R terminal (launched by clicking on Rterm.exe). I get: Process Name: Rterm.exe PID: 14596 Path: C:\PROGRA~1\R\R-43~1.1\bin\x64\Rcmd.exe Result: SUCCESS Detail: PID: 6820, Command line: C:\PROGRA~1\R\R-43~1.1\bin\x64\Rcmd.exe SHLIB --help Best regards, Christophe ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
