Dear Zak, that method can select programaticaly by row index or value:

g <- gtable(mtcars, cont = gwindow("test"))
svalue(g, index=TRUE) <- 1 ## by index
svalue(g) <- 22.8          ## or by value

For the latter, the constructor has an argument chosencol, which by default is
the first column. In this example, the values aren't unique, so the choice is
maybe not as expected.
