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> ->

Hello - I am noticing some strange errors when using the grid package, but (apparently) only after loading the tcltk package. The interaction here does not make sense to me, and I'm wondering if anyone else can reproduce this, or if it is specific to my setup. Here is my sessionInfo: sessionInfo() R version 2.6.2 RC (2008-02-04 r44332) i686-pc-linux-gnu locale:

With 2.7.0 patched (not tested with 2.0.0), I get an error message in a program that ran correctly in R 2.6.2 when the grouping factor of a stripplot contains an Umlaut: I am aware that there are a few locale-changes in R 2.7.0, but I could not easily locate who's at fault Dieter library(lattice) dt = data.frame(x=rnorm(100),y=1:100,levs= as.factor(c("Gru","Gr?")))

Hi R users, Im trying to install XML source package (in window platform) using the following command. *install.packages(pkgs = "C:\\Documents and Settings\\skang\\Desktop\\Softwares\\R\\Library\\XML_2.6-0.tar.gz", repos = NULL, type = "source")* and get the following result. gzip: stdin: unexpected end of file /cygdrive/c/Rtools/bin/tar: Unexpected EOF in archive

Hi all, I am struggling with remote R sessions and a (I suspect) locale related encoding problem: Using the X11 device (X11forwarding enabled), whenever I try to plot something containing umlauts using ggplot2, I am seeing sth like ,---- | Error in grid.Call(L_stringMetric, as.graphicsAnnot(x$label)) : | invalid use of -61 < 0 in 'X11_MetricInfo' `---- Using base graphics is fine

In this connection, note the following > a4 <- 4 > plotThis <- bquote(alpha==.(a), list(a=a4)) > do.call(plot, list(1:10, main=do.call(expression, c(plotThis)))) > do.call(plot, list(1:10, main=do.call(expression, plotThis))) Error in do.call(expression, plotThis) : second argument must be a list > ## Whereas plotThis has class "call", c(plotThis) has class

Hi, I'm trying to understand whether the use of substitute() is appropriate/documented for plotmath annotation. The following two calls give the same results: > plot(1:10, main = expression(alpha == 1)) > do.call(plot, list(1:10, main = expression(alpha == 1))) But not these two: > plot(1:10, main = substitute(alpha == a, list(a = 2))) > do.call(plot, list(1:10, main =

Hello, I have a gene expression matrix with columns being samples and rows being genes. I would like to display the expression values for each gene. I have two groups which I colour differently. The aim is to see if there is any difference between the two groups consistently across genes. So the following works well:

Dear R Gurus, I have a fairly simple problem, but I haven't been able to find the answer on 'the google' or in the r-help archives. I am generating plots on both Windows and OS X where I need to guarantee that the font used is Arial. In my plot command I specify 'fontfamily="Arial"'. The problem is that on Windows I'm getting the following warning: Warning

I install the Chinese font "Kaiti TC" on my mac, but I can't print the figures to pdf file by "marrangeGrob" command, which is in the package "gridExtra". Error message after I type "ggsave(......)"

I know that it has been discussed in the past, but I wanted to ask to revisit the idea of exporting is.formula <- function(x) inherits(x, "formula") from 'stats', parallel to is.data.frame() in 'base', given how widely formulae are used these days in conjunction with data frames, even outside of model fitting functions (e.g., for split-apply). One could argue

Thanks, Paul. Following your solution, I got this error message: Warning message: In cairo_pdf("test_plot_chinese.pdf") : failed to load cairo DLL Is there anything else I need to install?

Hi, Sorry to bother you with this question here. I tried to install Macports on my Mac OS Sierra, and type "sudo port install cairo", but it did not respond. I haven't seen any file name or app called Macports, but one file called "port" which is located at loca/bin/port" How should I do it? Thanks, John ******* Last login: Sun Oct 15 02:52:49

Hi, Following Paul's instruction, I have installed the Cairo. I tried to run the program, and there is no error message at all. I did see the Chinese title in the plot if I ask my RStudio to show the plot (if I type "p1"), but the pdf file shows the plots without the Chinese titles. library(ggplot2) library(gridExtra) df1<-data.frame(x=1:2, y=3:4, z=5:6) #p1<-ggplot(df1,
