`gtable` name gets reset on `[<- `

[landroni]

Consider:

w <- gwindow("gtable example", visible=FALSE)
g <- gvbox(cont=w)
tbl <- gtable(names(mtcars), cont=g, expand=TRUE, fill=TRUE)
visible(w) <- TRUE

Now set the table header name:

names(tbl) <- "Variables"

And notice that the name gets reset on reinitializing the table items:

tbl[] <- head(names(mtcars))

This seems like a bug. Could it be fixed, so that the header name is never dropped?

Changing it isn't hard, but the problem is one can reshape the table when set via [<-, so the names may not be apt or even the right length. I'd suggest a wrapper to store the names, call [<- and then reset the names if you do this a lot.

Oh, I seem to have found a workaround:

tbl[] <- data.frame("Variables"=head(names(mtcars)))

Should this be documented?
