Subject: R-beta: command-line editing not working in Debian Linux version
Date: Sat, 17 Jan 1998 16:06:50 -0500
I get great flexibility with command-line editing through the "readline"
library in the "bash" editor and the "ncftp" tool. S-Plus has this editing
and I see in the preliminary "Notes on R: A Programming Environment for Data
Analysis and Graphics", page 65, that "R -e" might give this functionality.
Typically, one can use either vi or emacs commands to go back through previous
commands and edit the current command line.
I notice that the readline library is not compiled into the Debian Linux
R.binary (ldd R.binary). Perhaps this was an oversight, or perhaps
command-line editing has yet to be added.
I notice that for vi editing style one ought to set (in "bash" shell)
export S_CLEDITOR=vi
however, hopefully, the readline [not the S/R readline() function, but the
readline library] file ~/.inputrc parameters would work to set "vi" mode and
other readline parameters (if the readline library gives this command line
functionality in R, that is).
