similar to: strange behaviour with rotated viewports in grid

Dear All, I am trying to find a way to plot a dendogram in reverse, that is, if the terminal leaves are labelled 1-10 bottom to top (or left to right), I would like to be able to plot it in a way such that if would display 10-1 bottom to top or left to right. Any idea how to achieve this? Thanks in advance, r. Dr. Rafael Najmanovich European Bioinformatics Institute Wellcome Trust

Hi, I am using R 1.9.0 (2004-04-12) for Mac OS X. I am having trouble printing to a jpg file. This only happens when I use R in batch (with the BATCH option) mode. If I launch the R GUI or the command line version and run the script from either, I have no problems. Only when running in BATCH mode I get a file with the same name as my script where I find the following message at the end:

Dear community, I am writing a wrapper for '[' operator, which is a generic method declared as function(x, i, j, ..., drop). It turns out that I need to parse the '...' argument and this is where I am stuck. Generally what I need is the following. Say the call is obj[1, 1, 1:10, 3] - here '1:10, 3' is passed into '...'. What I need to evaluate that '...'

The XML package relies on libxml2.dll (e.g., bundled with the CRAN binary) installed in library/XML/libs. Unfortunately, c:/WINDOWS/system32/libxml2.dll will be found and loaded before this. Is there any programatic solution? Thanks, Martin -- Martin Morgan Computational Biology / Fred Hutchinson Cancer Research Center 1100 Fairview Ave. N.

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"),

Dear useRs, Why are the rotated blue and yellow boxes in the example below clipped outside of 6 x 6 inch window in the middle of the page?? Where does the 6 x 6 inch window come from? I would like to make use of the entire page. > library(grid) > pdf(file = "FarmMaps.pdf", paper = "a4") > pushViewport(viewport( + width = unit(7.6, "inches"), height =

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),

Hi, I do not know if everybody finds index pages of the html-formatted R help useful, but I know I am at least not the only one who uses them extensively to get the overview of functions and methods in a package (even for my own package). Problems arise, however, if a lot of S4 methods need to be documented blowing out the index with (generally irrelevant) entries like:

Dear developers: I have just came across an (unexpected to me) behaviour of lists when assigning NULLs to list elements. I understand that a NULL is a valid R object, thus assigning a NULL to a list element should yield exactly the same result as assigning any other object. So I was surprised when assigning a NULL in fact removed the element from the list. Is this an intended behaviour? If

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

Dear all, I'm trying to get a series of lattice levelplots to appear in viewports in a particular way but struggling to exert fine control over their appearence. There are two conditions: (a) I only want the levelplot to appear (I don't want axes, colour key, etc) in the viewport and (b) I want the levelplot to expand to the maximum allowable space in the viewport while observing

Hi Community, I have a question about how to pass command line parameters to R script running in the batch mode. The problem is: there is a banch of data files which are to be processed by R script called from a web-server, i.e. in the batch mode. The web server generates data files and passes their names calling 'R CMD BATCH' one by one for every file. Now the question is how to

Dear lists: I am somewhat puzzled by the use of texi2dvi/pdflatex in R2.7.0. When building EBImage (bioconductor) with 2.7.0 I get the same error both in Windows and Linux, which reads the following: ** building package indices ... * DONE (EBImage) * creating vignettes ... ERROR /usr/bin/texi2dvi: pdflatex exited with bad status, quitting. Error in texi2dvi(file = bft, pdf = TRUE, clean =

Hello! I am undertaking my first attempt at using compiled C code within R and have run into this lovely problem when I call my C code (using .C). The instruction at "0x10001d1b" referenced memory at "0x01fa2000". The memory could not be "written". Now this doesn't happen every time and furthermore I've tested the code in plain C and it all works

I am setting up base plots -- one in viewport A and and one in B. This part works fine. But if I go back to A after having done B and add horizontal lines it seems to not use the correct coordinates. How do I tell it to resume using A's coordinates? I am already using par(fig = gridFIG()) but it seems that that's not enough to reestablish them. What happens is that when I go back to

Hi all, I was trying to set up an interface for using C functions in R. For this, my R file hello2.r is: --------------------------------------------------------------------------------- hello2 <- function(n) { .C("hello", as.integer(n)) } hello2(3) -------------------------------------------------------------------------------- and my hello.c file is:

Hi, I have an S4 class directly derived from 'array' as shown in the code below (EBImage package of Bioconductor 2.1, devel), it simply contains array adding a couple of slots: setClass ("Image", representation (colormode="integer", filename="character", compression="character", resolution="numeric", features="list" ),

Dear R developers, I've just encountered one "feature" of R-C extensions. If it is known, I would be thankful for any hints why it works this way (I found the way around, which is also mentioned here, but maybe it is not the best one). If it is however unknown, it might be considered for a "wish list". Consider a simple "aka" C function (the original
