From: Ville Syrjälä <ville.syrjala at linux.intel.com> This series first unifies all users of drm_atomic_helper_check_plane_state() to populate the clip rectangle with drm_mode_get_hv_timing(), and once everything is unified the clip rectangle handling is sucked into drm_atomic_helper_check_plane_state() away from driver code.

Dear All, is any way I can change the colours of the box and umbrella of a bwplot without having to go to the length of: box.rectangle<-trellis.par.get("box.rectangle") box.rectangle$col<-"black" trellis.par.set("box.rectangle", box.rectangle) etc... but straight from the call: bwplot(y ~ x | z, mydata) ? Regards, Federico Calboli

Dear All, Perhaps, what I am asking is impossible, but I am asking it anyway. I have got several pdf files with rows of colored rectangles: red rectangles should be read as 0; green rectangles as 1. No other color exists. Is there some way to have R reading the colored rectangles to a matrix or data frame converting the color of the rectangles to sequences of 01? Thanks in advance, Paul

How do I draw a rectangle across multiple plots on a device? E.g., def.par <- par(no.readonly = TRUE) par(mfrow = c(3, 1)) plot(1:10, rnorm(10), ylim = c(-4,4), type = "l") plot(1:10, rnorm(10), ylim = c(-4,4), type = "l") plot(1:10, rnorm(10), ylim = c(-4,4), type = "l") rect(2, -4, 3, 4) par(def.par) I want the rectangle to extend across the whole device. How

Hi, I need some suggestion on how I could modify the color on some rectangle that I have created using "image". In other words, I have a 5x5 matrix, say, m. m <- matrix(rnorm(25), nrow=5) I create a grid of rectangles by: image(m) Now I want to change the color of rectangle (3,3) to blue. I don't know how this could be done, and searching the web has given me no hint. Thanks for your help. -- saurav

Hopefully an easy question. When drawing a rectangles in a lattice plot key, how do you omit the black borders? Here is an example adapted from one on the xyplot help page: bar.cols <- c("red", "blue") key.list <- list( space="top", rectangles=list(col=bar.cols), text=list(c("foo", "bar&qu...

I am trying to create a lattice plot and would like to later, i.e. after the plot is drawn, add a grey rectangle behind a portion of it. The following works except that the rectrangle is on top of and obscures a portion of the chart. I also tried adding col = "transparent" to the gpar list but that did not help -- I am on windows and perhaps the windows device does not support

Hello everyone, if I have: x=1:10 y=1:10 plot(x,y) and I plot a rectangle rect(4,0,6,11, col=5) it covers the points of the graph. Is there a way to draw the rectangle under the points? I was thinking the a solution could be draw an empty plot then draw the rectangle and after the points, but it did not work. Any idea? thanks for your help H. [[alternative HTML version deleted]]

Hi I want to draw a rectangle behind a barplot such that it highlights those particular bars from the rest of the plot. I have figured out how to draw a barplot(), and then how to draw a rectangle of the correct shape and size (using rect()), but when I use rect() it draws over the top of the bars, and then when I re-draw the bars, it draws with a white background, thus eliminating my rectangle!

Hello R friends, I get quite confused in using the grid graphic function grid.pack( ) and grid.frame ( ). Here is a simple example: library(grid) grid.frame(name="frame1") grid.pack("frame1",rectGrob(width=unit(0.5,"npc"), height=unit(0.5,"npc"), gp=gpar(col="red"))) what I expect is a rectangle with half the default device's

Hello, I would like to build rectangles in a plot and use color and different type of hatching for filling rectangles. I don't find the way to draw hatchings. I'm thinking to build segment by segment inside each rectangle but I'm sure that exists a better way to do that. I didn't find any documentation about that. > s...

Full_Name: Joseph Scandura Version: 2.7.0 OS: Mac 10.5 Submission from: (NULL) (140.251.50.94) Since updating to 2.7.0 all plots that use image() (heatmap, etc...) now draw visible boxes around each rectangle in the plot. When there are many rectangles the surrounding color becomes dominant over the rectangle color and the overall image is borderline useless.

This makes scenarios like laptops with external monitors on Xrandr 1.2 work. Those e.g. have a 1280x800 output and a 1280x1024 output, completely overlapping each other. With this patch, outputDeviceForGeometry will return the smaller head for a rectangle that's completely inside the smaller head and the larger head otherwise. --- src/screen.c | 88

For an application in image processing -- using R for statistical purposes -- I need to solve the following task: Given n (e.g. n = 100 or 200) points in the unit square, more or less randomly distributed. Find a rectangle of maximal area within the square that does not contain any of these points in its interior. If a, b are height and width of the rectangel, other constraints may have to be

on one of my Centos 5.4 boxes, a machine that's around 5 years old and has always run Centos and X, and has had the same Nvidia card in it for its entire life, I'm suddenly getting these lines in the xorg log file: (WW) NVIDIA(0): WAIT (2, 6, 0x8000, 0x00000000, 0x000003c0) (EE) NVIDIA(0): Failed to allocate clip rectangle (EE) NVIDIA(0): *** Aborting *** (EE) NVIDIA(0): Failed to

...e I could try. As a reproducible example, we can consider: library(lattice) bwplot(voice.part ~ height, data=singer, xlab="Height (inches)") I want the dots for the medians to be replaced by a line through the median. Any suggestions? Many thanks, Ranjan PS; Also, how do I get the rectangles to be filled? I tried the following: box.rectangle <- trellis.par.get("box.rectangle") box.rectangle$fill<-"opaque" (also tried "filled", "shaded", etc. to no avail) trellis.par.set("box.rectangle", box.rectangle) but get errors in plotti...

Hello fellow R users, I have a problem. I have created a barchart overlayed by an xyplot line, both of which read off the same Y axis. The problem comes when I try to generate a key. It seems that I can only create either two lines, or two rectangles. I would much prefer to have the barchat series depicted by a rectangle, and the xyplot series by a line. Is there a way to do this? Your help is much appreciated. James -- View this message in context: http://www.nabble.com/Lattice-xyplot%3A-Line-and-Rectangle-in-legend.-tp23050031p23050031.h...

Hi all, I've got some problems when changing the trellis settings for the lattice plots. The plots look exactly as I want them to when calling show.settings() as well as when plotting them in the graphical window. But when printing to a pdf file, none of the settings are used!? Does anyone know what might have happened? Because the when changing the trellis settings, these should remain in

Dear All I have a problem with the height of the boxes in the key in the following. (The text is over 2 lines to accentuate the problem of no space between the rectangles.) Is there an easy way to put a space between the rectangles; size controls the width but there appears to be nothing for the height? xyplot(1~1, key = list(corner = c(0.8,0.8), cex = 0.6, title = "Functional Groups",...

Dear R wizards: sorry to bug everyone twice in one day. I would like to annotate my graph by putting text strings into rectangle boxes with a little cartoon-like bubble with a lid pointing to a specific location. I can draw some sort of bubble-with-lid using the R primitives. (has anyone done something like this already?) the problem where I am stuck is that the width of the rectangle must
