[R] State "disabled" to "Normal" menu

[John Fox]

Dear Handa,

It's very difficult for me to tell from your message what it is you're
trying to do. Are you simply a user of the Rcmdr, or are you trying to
write a plug-in?

If the former, Rcmdr menu items are disabled when they are for some
reason inappropriate to the current context. For example, before
there's an active data set, (almost) all of the statistical-analysis
menu items are disabled; similarly, if your data set has no factors,
then menus items for operations requiring factors, such as building
contingency tables, are disabled.

If the latter, the next-to-last field in each line of the
menu-definition file is (optionally) a quoted logical expression: if
the expression evaluates to TRUE, then the corresponding menu item is
activated; if FALSE, it is not. For example, for the two-way
contingency table menu item, the activation field is "factorsP(2)",
which evaluates to TRUE if there are at least two factors in the active
data set.

I hope this helps,
 John
