Hello Folks. This must be a silly question with a (not) obvious (to me) answer. Consider this: tmp <- matrix(1:200, nrow = 20) vec <- 300:309 tmp[9,] <- vec # replacing one row works fine p <- c(3, 11, 17) tmp[p,] <- vec # replacing multple rows pastes the values down a column and recycles vec. What I want to do is replace multiple rows simultaneously at once. I suppose I can

Hi All... I haven?t found mention of this error anywhere. I'm trying to draw spline curves using grid graphics. Most of the time, I have no problems, but I have some data sets that give the error in the subject line. I'm not sure which end points are identical, but the end points passed to the function are definitely not identical. Any assistance appreciated! Bryan tst <-

Hello R Users: I have 3 packages that I authored and they build and check just fine locally. However, when I try to install the local source packages (from the .tar.gz), I get the following message: Error in `+.POSIXt`(as.POSIXct(origin, tz = tz, ...), x) : could not find function "%is.a%" In addition: Warning message: In install.packages(file.choose(), .libPaths()[1], NULL, type =

Dear all, how can I use vcovHC() to get robust/corrected standard errors from an arima() output? I ran an arima model with AR(1) and got the estimate, se, zvalue and p-value using coeftest(arima.output). However, I cannot use vcovHC(arima.output) to get corrected standard errors. It seems vcovHC works only with lm and plm objects? Is there another way I can get robust/corrected

Dear Group, I am looking for ways to use R and Matlab. Doing the data transformations in R and using the data in Matlab to analyze with some pre-defined scripts. Any good ways to transfer the data into matlab in its most recent version? I tried using R.matlab but the writeMat output is not readable by Matlab. I just need to output a data.frame and read it as is into matlab where I can do any

Dear all, I am having a problem using grid when rotating a viewport. It seems to plot everything on a grey background colour which I am not able to get rid of. Even book examples such as that that plot figure 5.10 in P. Murrell's R Graphics book show the same behaviour. The following example illustrates this issue. I would appreciate if anyone has a way to solve this. Best regards,

I know this has probably been asked before, but, I'll ask anyways: Workspaces/Desktops/whatever on the top and bottom of the cube, is there any chance this will ever happen? I love how in gnome you can have work spaces in rows/columns, and i tend to have 4-6 workspaces (well 6, but only 4 gets used all of the time, but its nice to have the "buffer" workspaces. since using compiz

Hello, I am using compiz from git (20070207). And I have a problem thats not so easy to reproduce: (note this is happening for a long time now duno when it started but I never saw it with 0.0.13 which was in fc6 by default). Sometimes a window is always shown in the tasklist no matter on which viewport I am now. clicking on it moves to the viewport where the window acctually is. This does not

As the subject says, moveWindowToViewportPosition only takes an x argument. Shouldn't it have a y argument too for vertical viewports? -- Travis Watkins http://www.realistanew.com

Commit 246ca4b001 ("nv50: implement multiple viewports/scissors, enable ARB_viewport_array") added dirty tracking to scissors/viewports. However it neglected to mark them all as dirty on a context switch. This fixes an apparent regression in webgl in chrome, but probably in any application that switches contexts.

Hello! There is something wrong with nested viewports in grid package (I have tested it in R-1.8.0, may be it is different in other versions). Here is an simple example of a feature which seems strange to me: x11() rec<-T push.viewport(viewport(xscale=c(-10,10),yscale=c(-10,10),gp=gpar(col="magenta")),recording=rec) #Parent viewport with scales -10:10

I'm trying to create a layout with named viewports that I can use for other functions. I create the viewport tree that I want, and a list of grobs with the viewports describing where they should go. library(grid) vp <- vpTree( viewport(layout=grid.layout(2,2), name="layout"), children=vpList( viewport(layout.pos.col = 1, layout.pos.row=1, name="tl"),

Hi all, What's the best way of placing a grob into muliple viewports? I've been using code like: plot_grob_matrix <- function(gm, type=deparse(substitute(gm))) { grid <- expand.grid(x=1:nrow(gm), y=1:ncol(gm)) do.call(gList,mapply(function(x,y) editGrob(gm[[x,y]], vp=vp_path(x, y, type)), grid$x, grid$y, SIMPLIFY=FALSE)) } vp_path <- function(row, col, type) {

Dear R-users, I have got the following problem. I need to create 4x2 arrays of xyplot's on several pages. The plots are created within a loop and plotted using the print function. It seems that I cannot find the proper grid syntax with my viewports, and the more/newpage arguments. The following script is a simplification but hopefully will suffice to illustrate my problem. Any suggestion

list(...) I can not get at the grid viewports in a ggplot2 plot. I know there is supposed to be a viewport called "panel_1_1" but downViewport() can't find it. Has the viewport been popped? I had a quick look at the functions involved (eg ggplot_plot) but there is no obvious problem there. > library(ggplot2) > qplot(1:10, 1:10) > current.viewport() viewport[ROOT] >

Hi all, I'm trying to generate a plot containing a scatterplot, with marginal densityplots for x and y. However, when I try to generate a vertical densityplot, I get the message "warning: can't clip to rotated viewport", and nothing shows up. I'm probably misunderstanding how viewports are meant to be used, so if someone could give me a hint, I'd be most grateful. my

The following code, though not brilliant, works on an A4 page. It might look odd on other devices of a very different size. =============X8------- cut here ---------------------------- require(grid) wide <- 15 vps <- grid.layout(nrow = 3, ncol = 4, widths = unit(rep(1, 4), rep("null", 4)), heights = unit(c(99, 1, 99),
