Interactive Input Problem

Hi,
I built and installed R-base-1.7.0 on SuSE 8.2 without any problems, but the
interactive R interpreter, has problems with cursor movement:

ls()

character(0)

^[[A^[[B^[[D^[[C^[[A^[[D^[[C^[[B^[[D^[[A

These ugly characters are produced by the arrow keys. Does anyone know how to
fix that problem?

Ciao

that looks more like a problem with your shell. which one are you using? perhaps
it it solved by using another one e.g. bash.  otherwise you can find at the end
of the *.pdf "R-intro" http://cran.r-project.org/doc/manuals/R-intro.pdf  a
chapter called: the command line editor perhaps that helps.

Sorry, no, no shell is involved.  This is what happens in Unix R if the
readline library is not compiled in/activated (you can start R with
--no-readline).

Since you said you built `R-base-1.7.0' (not sure what that is: an SRPM?)

my guess is that you don't have the readline development tools on your
system.  Take a look at the configure output, and see what it said about
readline. You may need to install libreadline-devel or something like
that.
