similar to: lattice contourplot background covers inward-facing ticks

I'm working on a contourplot( ) graph, the subject of several previous posts to this list. The contours express probabilities from 0 - 1, but the key that is automatically generated by contourplot pads the probability scale with values that are impossible (i.e, range goes from -0.2 to 1.2), which will be confusing to those who view the plot. How can I get the scale to just run from 0 - 1?

Hello I'm using the following call to create a contourplot: library(lattice) m <- as.matrix(read.table("data.txt")) contourplot(m[,3] ~ m[,2] * -m[,1], at = c(1e-6, 1e-5, 1e-4, 1e-3, 1e-2, 1e-1), scales = list(x = list(log = 10, labels = c("1", "10", "100"),

Friends: I wish to overlay data points on a contour graph. The following example produces a nice contour plot, but I have not mastered the concept of using panel functions to modify plots. Can someone show me how to overlay the data points (given after contour plot statement) on the contourplot? --Seth model <- function(a,b,c,X1,X2) # provide model function for contour

Hello, A made a xyplot using the lattice library in R (latest version). The publisher of our paper has requested: 1. all tick marks should point inwards instead of outwards. 2. All lines should be thicker (lines, axes, boxes, etc. Everything). Lines is easy...I used: lwd=1.5 but what about the lines of the axes, and the lines that build up the plot itself?....? Any

Hi all, Could anyone help answer the following questions, please? (I'm using R-1.8.1-4 on Fedora Core 1 and very new to R) (i) Is it possible to specify a font family (e.g. courier or helvetica) when graphing? (ii) How can I make ticks point inwards on all four sides of a plot? Is it possible to have minor and major ticks? (iii) How would I specify a symbol "\sim" (i.e.

I can't figure out how to add tick marks on both my X and Y axis. For example, my X axis ranges from 0 to 1 and there are both a tick mark and a number label at the X-axis values of 0.2,0.4,0.6. and 0.8. I want to add tick marks to the figure at every 0.1 value. This will help a viewer determine the values on the x axis. I included all of my code. I apologize but it is very long. I am

Dear group, I tried to generate labels for every second tick in lattice (qqmath). Version: 0.14-16 Date: 2006/12/01 R version 2.4.1 (2006-12-18) An example: library(lattice) numy=100 y=runif(numy,min=0,max=1) sig=0.05 numsig=length(which(y<sig)) tck.no=11 # number of ticks tcks=1:tck.no labl=as.character(0.1*tcks-0.1) # label for all ticks labl[seq(2,tck.no-1,2)]="" # delete

Hi, one of the nice things about contour is that it labels all contour lines. contourplot only labels each particular elevation a single time. i.e., if there are two contour lines corresponding to z = 45, it will only label one of them. is there a way to get contourplot to automatically label all the contour lines, even those that are repeated? i ask because i want to plot contour plots *w/

Hi - I have a dataframe with 4 variables - long, lat, temp and year. I would like to plot temperature by lat and long in contour plots by year. There are 391 data points. When I try contourplot(temp~long*lat|year,data=hake,cuts=10,labels = TRUE,contour = TRUE,pretty = TRUE,region=TRUE) I get plots with dots around by data, but not contour lines or filled in regions. I have also used the

Dear R users, I need to add minor axis ticks to my graph. In traditional R this is easily achievable by simply adding a second axis with the minor ticks. But how to do that in trellis? I am already out of ideas. Any suggestions will be appreciated. Best regards, Martin ----------------------------------------------------------------- ?????????? ??????????? ? ?????? ?? ??????????

Dear R gurus, I have got stuck on how to customise the colorkey generated by levelplot and contourplot, in the lattice package. This best illustrated by an example: library(lattice) levelplot(volcano^20/1e45,at=c(0,0.001,0.01,0.1,1,10)) The reason for raising the volcano dataset to the 20th power is to create a dataset with a large vertical exaggeration - this is similar in nature to the data

Hi All, I want to add one point to contourplot().  I used contourplot() in my code like contourplot(z ~ a + b |c, data) I understand there is plot.axes argument for filled.contour(), but it  did not work for my code. I also tried plot() and text() for contourplot(), but got this error: "plot.new has not been called yet" Any suggestion for adding a point in contourplot()? Thank you very

If I have a contourplot (in the lattice package) and I want to add straight lines to it, how do I do this? I see that there are llines() and lsegement() functions for lattice plots, but they don't seem to do anything in this case: library(lattice) library(KernSmooth) x=rnorm(10000) y=x+rnorm(x,0,.5) a=bkde2D(cbind(x,y),.7) z=as.vector(a$fhat) grid=expand.grid(x=a$x1,y=a$x2) grid$z=z

Hi, I have done the interpolation for my data and I was able to create the contours in multipanel with the help of Pascal. Now, I want to clip the contour with the shapefile. I want only the portion of contour to be displayed which falls inside the boundary of the shapefile. The data mydata.csv can be found on https://www.dropbox.com/s/khi7nv0160hi68p/mydata.csv The data for shapefile can be

Sorry if I am cluttering up this list with too many rank beginner questions. But I *am* a rank beginner, and I am at my wit's end with this one: I have a data frame df, with components x,y,z. This command to make a contour plot with lattice graphics works just fine: > contourplot(z~x*y,data=df,cuts=20) Then I try > contourplot(z~x*y,data=df,cuts=20,region=T) And it dies on me with

Hi, Is there a way to plot more than one trend surface using the functions contourplot() and wireframe(). I have found an add=T in contour(), but no equivalent argument in contourplot() and wireframe()? I have taken the example 11-2 (pages 441-451) from Design and analysis of experiments (Montgomery 2001, 5th edition) to see if this could be done in R. I have managed to plot individual

Hello, A weird thing is happening to me. I have a 128x128 elements matrix m with values between 0 and 1. If I do: R> library(lattice) R> contourplot (m, cuts=9) I get the following error message: Error in validDetails.text(x) : Invalid 'rot' value The same for any cuts >9. I can plot m with contourplot(m, cuts=8) but this is not detailed enough. The 'normal'

Hi there, I'm a bit confused concerning the axis tck setting in the lattice package as the ticks on left sided axis aren't drawn at all with the following setting: dados <- data.frame(varsep = factor(rep(1:2,10)), i = runif(20)) library(lattice) my.theme <- list( axis.components = list(left = list(tck = 1, pad1 = 1, pad2 = 2), top = list(tck = 0, pad1

Hi, I am gradually moving from the classical R plot functions to the library Lattice I have some questions about contourplot () and its arguments: 1/ I am working on geographical coordinates which makes necessary that the X (longitude) and Y (latitude) units be represented with the same distance on screen. This was obtained in the classical R plots with plot.default(x,y, asp=1,...) and then

Hello, I try to increase the distance between tick labels and ticks in a lattice wireframe plot. Here's a minimal example: ## Minimal example x <- y <- z <- c(1,2,3) df <- data.frame(x, y, z) wireframe(z ~ x*y, df, scales = list(arrows = FALSE, col = "black", font = 1, tck=0.6)) I tried the axis.components option
