Dear all, I got a couple of warnings using panel.levelplot.raster, In panel.levelplot.raster(..., interpolate = TRUE) : 'y' values are not equispaced; output will be wrong although I was quite sure my data were equally spaced (indeed, I created them with seq()). A closer look at the source code reveals that the function tests for exact uniformity in grid spacing, if

Hello there, could you please help to modify gpar() properties of a cell inside tableGrob() output. In the following example I want to have different color for one out of 4 cells require(gridExtra) z<-matrix(1:4,2,2) grid.draw(tableGrob(z)) The only way I found for now how to do it is to do something like this downViewport(current.vpTree()$children[[1]]$children[[6]]$name)

I'm looking for a way to create a pdf report that contains multiple graphs on one page as well as tables (ideally with some lines below categories etc.) . I have used the pdf(filename) followed by dev.off() to date but this prints one graph per page and does not seem to have functionality for tables. Thanks Sent from my BlackBerry? wireless device

Dear All, Consider a matrix (N x N) where each entry is either zero or one (can hardly get any simpler). Now, I would like to plot it as a 'chessboard' where every matrix entry is a black (1) or white (0) square. Whatever tool I use to plot it, it should not try to interpolate the data at all. I found some online references http://www.phaget4.org/R/image_matrix.html but probably I can

I'm just beginning R, with book Using R for Introductory Statistics, and one of the early questions has me baffled. The question is, create the sequence: 1,2,3,4,5,4,3,2,1 using seq() and rep(). Now, as a programmer, I am punching myself to not be able to figure it out.. I mean, as simple as a for loop, but using seq, I am stumped. I would think c(1:5, 4:1) would be the brute force method

Dear List, consider the following scenario: setClass(Class = "A", representation = representation(B = "B", C = "C")) setClass(Class = "B", representation = representation(C = "C")) setClass(Class = "C", representation = representation(something = "character")) Obviously, the collation for sourcing these defs needs to be: C,

Hi, Working on a report that is going to have a large number of graphs and summaries. We have 80 "groups" with 20 variables each. Ideally, I'd like to produce ONE page for each group. It would have two columns of 10 graphs and then the 5 number summary of the variables at the bottom. So, perhaps the top 2/3 of the page has the graphs and the bottom third has 20 rows of data

Hi to all, Here is a question which I cannot solve. Appreciate so much for any suggestions! I have a squared region which is irregularly divided into many rectangular patches. Each patch is associated with a value, and two patches possibly share a common value. I hope to fill in each patch a pattern according to its value. For instance, if a patch has value 1, then I fill in that patch

Hello, I submitted this bug report to r-core and got a rejection saying I should post to r-help. This is my first time ever submitting a bug report, so forgive me if I'm using some wrong format. So, here's my bug report: Component: Graphics OS: Mac OS 10.5.8, X11 XQuartz 2.5.0 Summary: In the symbols function of the graphics package, scaling of the y-axis is wrong, causing symbols

Hi, R-Helpers, I would like to ask about multiple graphs in one figure. I tried to execute the following codes. xlim <- c(1,100) ylim <- c(1,4) plot(NA, xlim=xlim, ylim=ylim) > x <- c(1:100) for(j in seq(1,10,by=1)) { y <- j*x^2+log(j) lines(x, y) } In the above codes, I had to arbitrarily set up the coordinate range of the figure in advance before

Hi R-fans, I would like put out a question to all R users on this list and hope it will create some feedback and discussion. 1) What are your 3 most useful R package? and 2) What R package do you still miss and why do you think it would make a useful addition? Pulling answers together for these questions will serve as a guide for new users and help people who just want to get a hint where to

My name is Jaime Loureiro and I work in the Network & Applications area in University of Vigo. I am writing to you hoping you can help me with some libvirt graphics issues. I was analysing the source code of the libvirt in order to find how to access the display of each virtual machine. We are trying to generate a video streaming from the graphics content, though it is not easy to find what

Dear list, I wish to visualise some 4D data as a kind of colour / translucent cloud in 3D. I haven't seen such plots in R (but perhaps I missed a feature of rgl). The easiest option I found would be to export the data in povray's df3 (density file) format and visualise it with povray. The format specification baffles me a little, http://www.povray.org/documentation/view/3.6.1/374/ ;

  Hola,   Por favor, ¿podríais indicarme qué recursos (librerías o ideas) pueden resultar de utilidad para crear un gráfico del estilo del de la figura 3.8 del siguiente link?   http://www.tsc.uvigo.es/BIO/Bioing/ChrLDoc3.html#3.5   Actualmente estoy utilizando funciones muy básicas y la verdad es que no me encuentro muy satisfecha con el resultado.   Muchas gracias.   Eva [[alternative HTML

Dear members, I am performing multivariate analysis on marine benthic populations using R. At first glance I found ca and VEGANO packages to be the suitable for the task, but neither has incorporated Detrended Canonical Correspondence Analysis (DCCA), which is just the method I want to apply on my data. I've looked for alternative packages containing the method, but my suspicion is that
