I need to make a fairly complex animated graphic and decided to use grid for it. A very simple example of what I need: ##============================================================================== library(grid) grid.newpage() pushViewport(plotViewport()) pushViewport(viewport(xscale = extendrange(c(0, 100)), yscale = extendrange(c(0, 100)))) grid.xaxis() grid.yaxis() rectNames <- paste("r", 1:100, sep = "") for (i in 1:100) { grid.rect(x = unit(sample(0:100, 1), "native"), y =...

...ffort. Can someone explain how to keep the column of boxplots on the same page as the rectangles (even though I've tried new = TRUE) ? Also, would it be hard / possible to match up the middle of each boxplot to the middle of each rectangle ? pdf("tmp.pdf", h = 6, w = 10) pushViewport(plotViewport(c(5, 5, 4, 2))) pushViewport(viewport(layout = grid.layout(4, 6))) for(i in 1:5) { for(i2 in 1:4) { pushViewport(viewport(layout.pos.row = i2, layout.pos.col = i)) grid.rect() popViewport() } } pushViewport(viewport(layout.pos.col = 6)) plot.new() par(plt = gridP...

...usually not a trivial task; the default behavior of these functions seems to work well. The problem with this strategy is that I cannot figure out how to "recover" the positions of these ticks when you do NOT specify the 'at' argument. For example: grid.newpage() pushViewport(plotViewport(c(5, 4, 2, 2), name = "myvp")) # This draws a default xaxis a = grid.xaxis(name = "myX") # What are the tick marks? grid.get("myX")$at # NULL # But if I specify an 'at' argument... grid.edit("myX", at = seq(0, 1, length = 10)) # ...I can get at the...

...eral years of data so I would like to be able to have labeled tick marks only intermittently (not one per date). I can transform the initial data from a date time string into POSIXlt or POSIXct, or Date objects. The issue is that when I try to layout the plot using: dev.off() pushViewport( plotViewport( c(5, 5, 4, 2), xscale=c( min(foo), max(foo)), yscale=c(0,30) ) ) I get this error, regardless of whether "foo" is formated as POSIXlt, POSIXct or Date for the xscale.

Hello list, When using the grid package in R 1.60 under windows grid.lines and grid.line.to seem not to use the coordinate system as defined by the current viewport whereas grin.points does.

Hello everybody, often I plot boxplots with different number of boxes (up to 200 boxes). I'd like to give every box a readable label on the x-axis. Therefore, I decrease the fontsize of the names and plot them vertical. But if you zoom into the plot (pdf) you will find an offset between the tickmark and the label - the label is shifted to the right. If you vary the box.count in the
