ls() command

[Dennis Fisher <fisher@plessthan.com>]

Colleagues

I recently upgraded from Splus 6 to Version 7.0.0  (Red Hat Linux) and I have encountered behavior that I don't understand regarding the ls() command.

An example follows:

> BySubject <- ""

> ls()

[1] ".Last.value" "BySubject" 

> ls(pattern="BySubject")

Problem in cat(input, file = file, sep = "\n"): Couldn't open file "/unix16992" for "w" (write): Permission denied

Use traceback() to see the call stack

I create an object "BySubject"; ls() confirms that it exists.

However, when I search for it using "pattern", I get an odd error message (underline).

Of note, umask is set to 0 and the parent directory has privileges 777, so there should be no longer "writing" locally.

Thoughts?
