Good question, but it is common for Windows installer programs to add a terminal backslash to PATH entries. E.g., on my Windows laptop I get > grep(value=TRUE, "\\\\$", strsplit(Sys.getenv("PATH"), ";")[[1]]) [1] "C:\\Python39\\Scripts\\" [2] "C:\\Python39\\" [3] "C:\\WINDOWS\\System32\\WindowsPowerShell\\v1.0\\" [4] "C:\\WINDOWS\\System32\\OpenSSH\\" [5] "C:\\Program Files\\nodejs\\" [6] "C:\\Program Files\\Pandoc\\" [7] "C:\\Program Files\\MiKTeX\\miktex\\bin\\x64\\" [8] "C:\\Program Files\\PuTTY\\" I did not add those entries by hand; all were added by installer programs. -Bill [[alternative HTML version deleted]] ______________________________________________ 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.
