search for: drawdetails

Dear all, I've tried all sorts of variations discussed in "R graphics" by Paul Murrell, but I still can't understand how to write a drawDetails method for a class derived from a gTree. Below is a minimal, dummy example where two strings are plotted in two separate viewports. I require the creation of the strings to be evaluated inside the drawDetails function because my real example will need to calculate a grob size on-the-fly (the viewpo...

I found just...

...far as I understand, lattice produces a list of class trellis, which is eventually displayed using the plot.trellis method. I am not sure if/how one can convert this list into a high-level grob. I tried the following, latticeGrob <- function(p, ...){ grob(p=p, ..., cl="lattice") } drawDetails.lattice <- function(x, recording=FALSE){ lattice:::plot.trellis(x$p) } p1 <- xyplot(1:10 ~ 1:10) g1 <- latticeGrob(p1) grid.draw(g1) # works fine but, fg <- frameGrob(layout = grid.layout(1,1)) fg <- placeGrob(fg, g1, row = 1, col = 1) grid.draw(fg) Error in UseMethod("de...

Hello there, could you please help to modify gpar() properties of a cell inside tableGrob() output. In the following example I want to have different color for one out of 4 cells require(gridExtra) z<-matrix(1:4,2,2) grid.draw(tableGrob(z)) The only way I found for now how to do it is to do something like this downViewport(current.vpTree()$children[[1]]$children[[6]]$name)
