Hi, Why does the upper left panel (in the plot below) not have a gray background? Cheers, Marius require(grid) require(gridBase) pdf(file="Rplot.pdf", width=8, height=8, onefile=FALSE) ## set up the grid layout gl <- grid.layout(5, 5, widths=unit(c(1.8, 8, 0.8, 8, 0.8), "cm"), heights=unit(c(0.8, 8, 0.8, 8, 1.5), "cm")) if(FALSE) grid.show.layout(gl)

Hi, I recently created a function which uses grid with a viewport constructed with grid.layout() to position four plots on a plot device. My question is what's the best way to programatically traverse each element of the viewport? The grid is 5x5 and the four plots occupy positions (2,2), (4,2), (2,4), and (4,4). Here's the viewport code: pushViewport( viewport(

Happy New Year to all R users! I have two short questions concerning a xyplot with a color key: 1) How do I properly place (align) the color key beside the xyplot? As you can see from the code listed below, the placement of the color key is not correct. I would like the upper and lower end point of the color key to be perfectly aligned with the upper and lower line of the xyplot. Adjusting

Hi, If I use the levelplot function of the lattice library, I always see small "squares" in the plot. They indicate the region for which the same color is used. If you have a levelplot of a function which is evaluated at 25x25 equally-spaced points you obtain 26 squares in x and 26 squares in y direction. That does not bother too much (but still bothers somehow...), but if you

Hello, I would like to create a sequence of plots (using a for loop). I read in the FAQ that print() has to be used in order to obtain any output. This works perfectly fine as long as I only consider one function call in the loop, but I would like to add mtext() to the each plot in the loop. Unfortunately, this did not work. Any suggestions? As you can see from the provided example,

Hi, This is most likely only a minor technicality, but I saw the following: On page 6 of the 'parallel' vignette (http://stat.ethz.ch/R-manual/R-devel/library/parallel/doc/parallel.pdf), the random-number generator "L'Ecuyer-CMRG" is said to have seed "(x_n, x_{n-1}, x_{n-2}, y_n, y_{n-1}, y_{n-2})". However, in L'Ecuyer et al. (2002), the seed is given with

Hi, why does format(10000, big.mark = "\\,") not give me "10\,000"? How can I get this kind of "big.mark"? Cheers, Marius

Dear expeRts, I would like to create a plotmath-label of the form X_1^\prime. Here is how to *not* do it [not nicely aligned symbols]: plot(0,0,main=expression(italic(X*minute[1]))) plot(0,0,main=expression(italic(X[1]*minute))) plot(0,0,main=expression(italic(X)[1]*minute)) Any suggestions? Cheers, Marius

Dear expeRts, I have two matrices A and B. They have the same number of columns but possibly different number of rows. I would like to compare each row of A with each row of B and check whether all entries in a row of A are less than or equal to all entries in a row of B. Here is a minimal working example: A <- rbind(matrix(1:4, ncol=2, byrow=TRUE), c(6, 2)) # (3, 2) matrix B <-

Dear R-users, I have a plot created with the code below. I tried to put some text to the right of the color key. I worked with grid.text and also viewport(), but couldn't achieve this. I know this should be simple, but I just couldn't figure out how to do it. How does this work? Cheers, Marius library(lattice) library(grid) myvec=1:10 data=data.frame(x=myvec,y=myvec)

Dear expeRts, I am not sure if I found a bug... I would like to create a function that itself creates a lattice plot without colors. Following http://www.mail-archive.com/r-help at r-project.org/msg64699.html I use trellis.device() to set the colors to FALSE. Whenever I call the minimal example below *with* trellis.device(), Quartz opens a window (I am working on a MAC), which it shouldn't,

Hi Simon, thanks for your quick reply. 1) ... so you can reproduce this? 2) Do you know a way how this can be 'foreseen'? We allocate larger matrices in the copula package depending on the user's input dimension. It would be good to tell her/him "Your dimension is quite large. Be aware of killers in your neighborhood"... before the killer attacks. Thanks & cheers,

Dear expeRts, I am a new user of rgl, below is my first trial to plot a simple function in 3d. I managed to put the axes in the right locations, but: (1) The xlab, ylab, and zlab arguments are ignored; how can I put in axes labels? (2) Since I removed the axes in persp3d() the viewport is too small; is it possible to keep the size of the viewport? (3) The box is not correctly drawn, there

Dear expeRts, I would like to colorize the backgrounds of a pairs plot according to the respective panel number. Here is what I tried (without success): count <- 0 mypanel <- function(x, y, ...){ count <<- count+1 bg. <- if(count %in% c(1,4,9,12)) "#FDFF65" else NA points(x, y, cex=0.5, bg=bg) } U <- matrix(runif(4*500), ncol=4) pairs(U, panel=mypanel) I

Dear expeRts, how can I decrease the space between the tick marks and the corresponding labels in an splom? See here: library(lattice) U <- matrix(runif(4000), ncol = 8) splom(U, axis.text.cex = 0.2) # => space between the [small] tick labels and tick marks is/seems to be too large I checked ?panel.pairs but could not find an option for that. Cheers, Marius

Hello all, I'm trying to write a function that produces a main plotting region with several square plots along the right side. Ideally the size of right side plots will scale only with the height of the entire plot, yet never overlap with another secondary plot. The following two snippets get close, however, as I resize the plot horizontally the right side plots (green squares) get smaller

Hello, I created several plot with ggplot2 dev mode. Now I want to combine the plots in a grid e.g. 2x2 with a fixed size of the output. What I am doing at the moment is: grid.newpage() pushViewport(viewport(layout = grid.layout(nrow=2, ncol=2, widths = unit(c(7.5,6.5), "cm"), heights = unit(rep(5, 2), "cm")))) print(plot1, vp = viewport(layout.pos.row = 1,

Hi, Both under the current R-devel (r66456) and a version from about 3 months ago, I experience the following behavior: > parallel::detectCores(TRUE) Error in system(cmd, TRUE) : error in running command > traceback() 3: system(cmd, TRUE) 2: gsub("^ +", "", system(cmd, TRUE)[1]) 1: parallel::detectCores(TRUE) > This is on Ubuntu 14.04.

Hi, Interesting "feature" in 10.11.4. I wonder if the process is killed before or after malloc() returns. If before, it seems very blunt: "You're asking too much and I don't like it so I kill you now". If after it doesn't look much better: "You're asking a lot and I don't like it but I give it to you anyway. I'll kill you quickly later". Why
