I've been told that my messages are being rejected because it is being posted via nabble in HTML format. I was advised to re-send this directly to r-help at r-project.org. My apologies if you get this twice. When I use bash + readline and ~/.inputrc contains "editing-mode vi", I can press "v" to switch to from the command line editing to a full vi session editing of a command. This doesn't seem to happen in R. Is there a configuration setting/file that I can set to get this behaviour? Furthermore, when using bash, the fc command allows me to edit the history of commands, and when I exit the editor, all the remaining (and likely modified) commands are submitted to the bash shell as if I typed them at the prompt. Is there a way to get similar functionality in R?
