similar to: lattice::panel.levelplot.raster too picky with unequal spacing

Dear all, I am puzzled by the following behavior of the new grid.cap() function, which appears to run out of time when capturing the output of a graphic. It works fine if I introduce a Sys.sleep(1) before executing more code, library(grid) quartz() grid.circle(gp=gpar(fill="black")) gg <- grid.cap() dev.new() grid.raster(gg) ## completely blank gg[gg!="white"] ## indeed

Hi, I would like to combine multiple xyplots into a single, multipanel display. Using R 3.0.1 in Ubuntu, I have used c() from latticeExtra to combine three plots, but the x-axis for two plots are on a log scale and the other is on a normal scale. I also have included equispace.log=FALSE to clean up the tick labels. However, when I try all of these, the x-axis scale of the first panel is used

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/ ;

My question is represented by the following example. For example, I have a character string a, which is defined as AA="list(x=1, y=2)" I want to take out the content of AA by using some function, so that I can obtain the following expression automatically. list(x=1, y=2) Does anyone know how to do it? Thanks a lot, -- View this message in context:

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

Estimada comunidad, estoy haciendo un grafico con la funcion xYplot (paquete Hmisc) para agregar barras de error a los puntos del grafico. Pero pasa algo que no me gusta: aparece el nombre de las series en el grafico. Alguien sabe como puedo eliminarlas ? no quiero usar ggplot porque ya tengo hechos todos los graficos con lattice. Aqui el codigo que uso y los datos (estan separados por tab, no

Dear R users, I want to plot a one variable continuous function f(x) vs x, x=[0,1]. Say for example: f(x)= x^2. Now, using the command plot(f~x) I will get a curve where the range of x-axis is [0,1] with all equispaced label. But, I need something else, and that is: my curve will be such that 80% on x-axis the range would be [0,0.5] and the rest 20% would contain [0.5,1]. Let me draw informally

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,

I have an irregular time series in a Zoo object, and I've been unable to find any way to do an FFT on it. More precisely, I'd like to do an NFFT (non-equispaced / non-uniform time FFT) on the data. The data is timestamped samples from a cheap self-logging accelerometer. The data is weakly regular, with the following characteristics: - short gaps every ~20ms - large gaps every ~200ms

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

Estimados, tengo el siguiente problema: Tengo que graficar la concentracion de un metabolito en algunas muestras contra la concentracion del solvente con que fue extraido. Las concentraciones varian desde cero (para un control) hasta varios miles de unidades de concentracion (miliMolar). Para que se puedan diferenciar los puntos en el eje X, se ha usado una escala logaritmica. Hasta ahi todo

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

I have some time stamped events that are supposed to be unrelated. I have plotted them and that assumption does not appear to be valid. http://metrak.com/tmp/sevents.png is a plot showing three sets of events over time. For the purpose of this exercise, the Y value is irrelevant. The series are not sampled at the same time and are not equispaced (just events in a log file). The plot is

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

Dear users, I am trying to export polygons from Arcmap into Spatstat to run some simulations using functions available in Spatstat package.
