Hi: I am coding some interactive interface using an xyplot from lattice. When a user clicks on a panel of the xyplot, a simulation is executed and the resulting data is plotted on the corresponding panel. The problem is that I start with an empty data frame and only fill it as the user request data from simulations. And, I have found it impossible to create a conditional plot that contains panels

Hi: I am a newbie using grid and lattice. I want to update a xyplot without redrawing and I was wondering if there is a way of adding a point to a pointsGrob ? For example, take the example from the "R Graphics Book" page 218-219: grid.newpage() angle <- seq(0, 2*pi, length=21)[-21] x <- cos(angle) y <- sin(angle) xyplot( y ~ x, aspect = 1) Lets say I take the pointsGrob

Hi: I would like to find out the panel of a xyplot matrix where a mouse clicked. I know this functionality is already bundled in trellis.focus but I can't use it because I am coding a stand alone application in Java using with GDCanvas as a graphics device. I tried calling trellis.focus from Java with: re.eval("t = trellis.focus()")); However it did not work for an embedded

Hi: (Tried to find a bug report about this issue, but was unable to find it, let me know if this is a known issue) I have been working on an interface to highlight xyplot panels on mouse overs in JavaGD but I have stumbled with what seems to be a bug in trellis.focus. I am using R 2.8 with lattice 0.17-15 *** To replicate the bug: 1.- display an xyplot. For example, from the xyplot help page:

Hi: I don't know if my explanation below is clear, so afterwards, I wrote a small a self contained annotated example that generates two plots. I execute simulations with different parameters settings that create several datasets, and for each parameter setting (or dataset) I can obtain different results by choosing a different random seed. I am stuck grouping data from the datasets and runs
