I'm not sure where to begin with this problem, but here I go.  I'm running
this on a Linux system using R 2.10.1

I've installed the IRanges package.  However, when I enter help(sort), it
shows that the topic 'sort' was found both in the IRanges and the base
package.  However, it ultimately returns an error message,

Error in structure(.External("dotTclObjv", objv, PACKAGE="tcltk"), class =
"tclObj") :
[tcl] grab failed: window not viewable.

Am I missing something obvious?

Thanks,
Andrew
