Hi All,
This is a slightly arcane question, but I'm wondering if anyone else uses vi
mode with R? On my platform, across several versions, there is some broken
behaviour. When executing commands like 'df)' (to delete up to the next
bracket) the cursor moves to the next ), but nothing is deleted. In general,
many delete/replace commands work only as movement.
Has anyone else come across this, and if so, did you find a fix?
The same commands work correctly on the command line, so I'm assuming the R
CLI has it's own built in version of readline, which is causing problems.
Or your assumption that it is GNU readline is causing you problems.
I'm currently running R2.8.1 on OSX 10.5.6, but the bug has been there for
both R and OSX upgrades. It isn't present on Linux.
The editing library on OS X is not GNU readline. By 'on the command
line' I guess you mean in bash, which does include GNU readline.
(Earlier versions of OS X did not use bash.)
If you want GNU readline, the solution it to build R to use it. This
is described in the R for Mac OS X FA!, section 2.1.3.
BTW, it is common policy on help lists not to answer questions about
topics in the FAQ, and the R posting guide asked you to check that
first. Especially when asked on the wrong list:
