similar to: Query for semi-transparency support

I am trying to run an R script to create a .png file containing a tree map on a headless Linux server using Xvfb. When I try to run tmPlot, I get the following errors and warnings: Error in grid.Call(L_textBounds, as.graphicsAnnot(x$label), x$x, x$y, : X11 font -adobe-helvetica-%s-%s-*-*-%d-*-*-*-*-*-*-*, face 1 at size 9 could not be loaded Calls: tmPlot ... <Anonymous> ->

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

Hi, I found in grid package, if the graphic parameters have zero length, R crashes. In the following code, I only tested `grid.rect()` and the `fill` parameter, but I think it should be similar as other grid graphic functions. In `gpar()` function, the graphic parameters are not allowed to have zero length, but we can make them with zero length by first generating a `gpar` object and then

Hi, I used the command ggplot as follows... p<-ggplot(a,aes(x=a$V1,colour=a$V2,fill=a$V2)) p + geom_density(alpha = 0.2,xlim=c(-10,10),ylim=c(0,0.5)) when I say, dev.print(device=postscript,file="/alpha/dct.pdf") I get Warning message: In grid.Call.graphics("L_polygon", x$x, x$y, list(as.integer(1L:length(x$x)))) : semi-transparency is not supported on this device:

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,

Dear list, I'm puzzled by the graphical output in the following example, library(grid) foo <- function(){ grid.rect(gp=gpar(fill="black")) print(get.gpar()$fill) grid.rect(width=0.2,height=0.2) } png("test.png", bg = "transparent") foo() dev.off() png("test1.png", bg = "white") foo() dev.off() It seems that the default value of

Dear R community, I am having trouble determining how to create the graph I want utilizing my relatively limited knowledge of R. So far I have been using the lattice library to create most of what I need. The dataset (enviro) consists of 2 variables (Temp and Precip) for each Day of a 2-yr period (Year). I wish to display Temp and Precip along the y axis plotted by Day on the x axis to allow

Hi all - I'm trying to generate lattice barchart graphs with missing values, and came across the following: This does not run. I would expect it to: library(lattice) D = data.frame(X=1, Y=factor(letters[2], letters[1:2])) barchart(~ X, D, groups=Y) Error in grid.Call.graphics("L_rect", x$x, x$y, x$width, x$height, resolveHJust(x$just, : invalid line type which is simply

Hi again! I put this question in another topics post before but I fear it might drown there. Is it possible to have transparent / alpha blended colors for pie charts? I am using the pies in a map of pies and those pies are sometimes overlapping so it would be great to see if another pie lies beneath. Thanks, Werner

Hey all, I'm trying to create a plot of two semi-transparent regions. The reason they need to be partially transparent is so that I can see if there's any overlap. Here's some example code: # BEGIN pdf(file="test.pdf",version="1.4") plot(0,0,type="l",ylim=range(-3,3),xlim=range(-1,5)) polygon(c(0,1,2,3,4,3,2,1,0), c(0,1,2,1,0,-1,-2,-1,0),

Hi, I see different results in png() and pdf() for polypath() on Windows when using the "winding" rule ## overlapping, both clock-wise x <- cbind(c(.1, .1, .6, .6, NA, .4, .4, .9, .9), c(.1, .6, .6, .1, NA, .4, .9, .9, .4)) pfun <- function() { plot(x) polypath(x * 0.8 + 0.2, rule = "winding", col = "#BEBEBE80") polypath(x, rule =

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Greetings, I've configured Samba for automated printer driver download by all Windows clients. However, I run into the following problem with NT4/2000/XP computers: Every user can connect to any printer and install the driver. (OK.) Only the printer admins can change hardware settings (f.ex. "Can it do duplex?"). (semi-OK.) BUT:

Hi Just to clarify, I think this IS a problem with grid.path() as well as polypath(). For the example you give, grid.path() diverts to drawing a polygon (because there is no 'id' specified), and the NAs in 'x' generate two separate polygons, which get drawn one on top of the other. The correct analogy to the polypath() example is ... x2 <- matrix(x[!is.na(x)], ncol=2)

I just updated to the latest beta package on my ubuntu system. I am sometimes playing with igowin.exe a small go program. there is only one bug, picture's transparency. it would be nice to get this fix eventually. thanks http://appdb.winehq.org/objectManager.php?sClass=application&iId=1669

Hello all. I'm new to asterisk and have been using and testing it for about a week now. My initial hope has been to use it as a sip<->h323 gateway to tie SIP & H323 based ip phones together with my Cisco AS5300 and Lucent MaxTNT/MVAM networks. I am currently running Asterisk 0.5.0 under Redhat 9 on a single PIII 800 with 256megs RAM. I have tried a couple CVS version from the past

My dilemma is this. My company is in the midst of doing some moves. Our network will be merged with another section of the company. They are completely MS servers, while all my servers are running linux / samba. Our new CTO told me that the company IS moving to Exchange 2003 (in ~ 6 months), and said that he is open to use linux for authentication, file servers, print servers, etc IF I

hi all, i have a simple scatter plot, and i'd like to make it so the scatter plot colors are slightly transparent. i see in a previous post that someone mentioned the "alpha" parameter, but i am not sure how it can be used with the 'plot' function [*]. for example, suppose i have: plot(mydata$column1, mydata$column2, col="red", cex=1) i now want to make it so

Hi, The added support for semi-transparent colours in `windows' under R-2.6.0 for Windows is much appreciated. However, I've discovered that issuing a `layout' (or `par' with arguments `mfcol'/`mfrow') call and then trying to plot several figures with semi-transparent colour on the same page results in only the first one being fully drawn. E.g. > x <-

Hello, I think you?re steps are right. But you install the driver from the wrong machine. I had the same problem. You must install the first driver from a NT4.0 box. After that you have a NT40 folder in your print$ share and you can add also the drivers for w2k or xp. Regards sven -------------- next part -------------- HTML attachment scrubbed and removed
