[R] Lattice: it seems, a bug in draw.key function

Dear r-help,

  Now I am drawing graphs with xyplot function.   

  In order to place a legend under the plots I use the key argument in the xyplot function.

  One of the 'key' components is 'divide', which defines a number of   points on the each line of the legend. The default is 3 points.   I would like a single point, so I set divide = 1.

  Call to xyplot didn't produce any points at all.

  The body of draw.key function contains the following   

pointsGrob(x=(1:key$divide-1)/(key$divide-1), y=rep(0.5,key$divide),


When key$divide=1, x is NaN...

Best regards
