similar to: contour(): lines & labels in different colours?

Hi, I want to display some contour labels. It works well, but the thickness of the label is to low. I tried the "labcex" command contour(x,y,z, labcex=2) But only the size is rising and not the thickness of labels. Only if i set the value to "labcex=10" the thickness is good, but the size is to big, so i can't see anything ;) Is there any command to rise the thickness

R-0.99.0a now plots contour labels from contour(), but the values in levels seem to be coerced to integer. Reproduce by: > set.seed(2) > contour(matrix(runif(36),nrow=6), labcex=1.2) and compare with: > set.seed(2) > contour(matrix(10*runif(36),nrow=6), labcex=1.2) Ray Brownrigg -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list --

Hi Folks, I have been using contour() to produce some contour plots (of a spatially-smooted density produced by kde2d()), with very satisfactory results. I now want access to the coordinates of the points on the contours, and it would seem that contour() does not return a value, so there is nothing from which these could be extracted. However, apparently contourLines() does, and it seems to be

Hello All, I am drawing four contour plots on a 2x2 layout. I need to downsize the contour line labels. cex and labcex do not seem to work. Any suggestions?

Is there an easy way to control the font size for the contour lines in plots of kde objects in package ks? The label size seems not obey the cex parameter (which probably would be the R way of doing it).

I'm trying to make a set of contour plots of bivariate kernel density estimates, showing three such plots overlaid, similar to this plot http://euclid.psych.yorku.ca/SCS/Private/Test/ridge-boot2.pdf except that I would like to have the contours *filled* (using transparent colors). To make this reproducible, I've saved the results of KernSmooth::bkde2D() in the following file:

In a contour plot having numeric values displayed next to the contours, is it possible to modify these numeric values so that they are bolded, enlarged, and/or placed differently? Much thanks in advance, David Paul, Ph.D. Battelle Memorial Institute 614.424.3176

Hello, I am trying to plot SADIE red-blue plots of cluster indicies using filled.contour. I want a plot which only has three bins for the data: <-1.5, -1.5 - 1.5, >1.5, but I am having trouble getting there. example X1 X2 X3 X4 X5 1 -5 -4.5 1.0 4.5 6 2 -3 -2.0 1.2 -1.0 3 3 0 0.0 0.0 -0.5 -1 4 -2 -3.0 1.0 1.5 3 5 -6 -2.0 0.5 3.0 2 example<-as.matrix(example)

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/

I found it useful to have contour be able to do line widths ... hope that the guts haven't changed an enormous amount in the current development version ... the patches are relatively trivial, mostly going by analogy with lty and col (although in my ignorance it took me a while to figure out what UNPROTECT(2) was and why it should be changed to UNPROTECT(3) ... hope this is useful.

I am using contour to draw contour lines onto a photo (jpeg) of a leaf on a white background. I have two problems: 1) The contour gets plotted at right angles to the jpeg image. I guess this is a problem of referencing the start and end points of the image matrix but I can't see how to over come this other than loading in a second image that has been rotated 90 degrees and plotting the

Hi Folks, I'd be grateful for good suggestions about the following. I'm plotting a family of (X,Y) curves (for different levels of another variable, Z): say 6 curves in all but could be more or less -- it's a rather variables situation. I'd like to label each curve with the value of Z that it corresponds to. The problem is that the layout (shapes, spacings, ranges of X over

Greetings all! I'm wanting to plot contours of a function, and I don't want to evaluate it at a dense grid of points (i.e. I don't want a huge array of values). Say I have a vector of x-values such as x <- 0.1*c(1:10), and the same for y <- 0.1*(0:10). I then evaluate a 10*10 matrix z of values of z = f(x,y). so I can then do CL <- contourLines(x,y,z) and get a list of

To everyone, Is there a way to extract coordinates or an equation from a "straight" contour line? Thanks. Cheers Julius Tesoro

Estimada comunidad, otra vez con una pregunta de formato, existe una forma simple (complicadas ya he encontrado) de cambiar el tamaño de las etiquetas de las lineas de contorno en un contour plot ?? de las posibilidades simples he probado con todas las opciones para etiquetas en par() pero las del interior del grafico no cambian muchas gracias, saludos, eric. -- Nota: las tildes se han

Hi all, Does anybody know how to add contour lines to a filled contour plot? I want to draw a single contour around values that are above a certain level (e.g., significant). The problem I'm having is that since the filled.contour command actually draws two plots (data and the key), adding contour lines paints them over both plots. Any suggestions? Thanks, Andy #~~~~~~~~~~~~~~~~~~~

Dear R-helpers, I'd like to be able to post-process contours coming from contour(). Does anyone have a version of contour() (or something similar) which will return the contour coordinates? In searching the archives I've come across a message in Nov 01 which had this on a wish-list, but I can find no later reference. With thanks, John Field Adelaide, South Australia

Is it possible to add labelled contour lines to filled.contour plot ? [[alternative HTML version deleted]]

Hi all, To my knowledge, the current version of contour.default() does not handle the 'asp' parameter. This can be embarassing when displaying eg geographical maps, etc... Submitted to the opinion of more experienced R programmers, contour.defaut() function should be changed according to the followings: line 7: add = FALSE,asp=NA,...) line 33: plot.window(xlim, ylim,

Is there an easy way to control smoothness of the contour lines? In the plot I am working on due to the undersampling the contour lines I am getting are jugged, but it is clear "by eye" these should be basically straight lines. In maps package I found smooth.map function, but maybe there is a more generic way of accomplishing the same thing. Ideally there would be an option to control
