using X11(antialias="none") plot(1:10) produces an incomplete plot with 2.7.0. under MacOS 10.4.11: both y-axes are missing.the y-ticks (except the tick at `2' wich is missing) including labels are there. this happens with a 1280x854 labtop monitor. is this known behaviour/a cairo bug? joerg

A rather strange situation here and I've not found the source of the problem. The point is to print a ternary plot matrix of compositional data with ellipses enclosing 95% of the variance in each plot. The ellipses display on the monitor, dev = x11cairo (see attached winters-x11cairo.pdf), but not when sent directly to a file, dev = pdf (see attached winters-pdf.pdf). Here's winters.acomp: structure(c(0.0666666666666667, 0.0612244897959184, 0.0434782608695652, 0.043956043956044, 0.05, 0.0161290322580645, 0.6, 0.571428571428571, 0.623188...

...variable appropriately." It's unclear what DISPLAY is appropriate. I have X11 forwarding set up on my machine (the remote machine). When we try to create a graphic in his ESS remote process, (e.g., hist(rnorm(50))), we get the following error: "Error in X11(... unable to start device X11cairo In addition: Warning message: In x11(): unable to open connection to X11 display" Does anyone out there use interactive graphics on their ESS remote sessions? If so, could you provide any help? We're really stuck and just need a step-by-step from anyone who knows. Thank you, Matt --...

X11() *is* by default the "X11cairo" device and that works, the same as the "Cairo PDF" device that Jeff mentioned above. Indeed, cairo_pdf("utf8-ex.pdf") # works nicely whereas pdf("utf8-ex.pdf") does not {for me, with default font families etc}, but rather shows the "..." instead....

Hi. Q. Is there a way to record a plot using grDevices::recordPlot() without opening an interactive (=visible GUI window) graphics device (not even for a flash of a second)? Related: help("recordPlot", package="grDevices") says: "These functions record and replay the displaylist of the current graphics device." Is the intention that recordPlot() should be able to

Hi dear all, In my laptop(ubuntu 11.10 64bit), I maintained a released R (2.14) and a developmental R, I can specify qplot(..., alpha = ) in R 2.14 , but when I try to use transparency in developmental R, I got a warning message and the plot is clearly not I want. minimal example: > qplot(data = mtcars, x = mpg, y = cyl, alpha = cyl) Warning message: In grid.Call.graphics(L_points, x$x, x$y,
