similar to: contour() labels (PR#441)

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

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?

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.

Greetings, All! I want to draw contour lines in red, using contour(), but also have the contour labels (for the level-values) in black so that they will stand out against a coloured background already generated using filled.contour() (the background shades from green at low levels of "risk" to red at high levels). In any case, contour labels in red are already somewhat inconspicuous

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 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).

Dear all, As a newbie in R I would like to do the following (simple?) thing: to plot a filled.contour plot over a map showing country boundaries (e.g. for Europe) What i do is: map('worldHires',xlim=c(-10,40),ylim=c(35,70),boundary = TRUE,border=0.1) map.axes() filled.contour(mslp, zlim=c(1000,1020),color.palette = colorRampPalette(c("blue", "white",

Hello, Using the data and code below I've been using R to compare output from two different solute transport codes, the red contours are from verified code while the blue contours come from some modified code I've been working on. The goal is for the contours to match, and although there is currently a slight discrepancy this would be expected. The plot shows a pulse of infiltrating

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

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:

Dear R users, I would like to create a filled.contour plot with colour bar and overlay a map. I need to create several of these representing variables with different spatial extents for comparison. When I try to fix the plot area size and axes limits as follows: par(fig=c(0,1.0,0.3125,1.0) filled.contour(x=seq((320/2)-180.5,(480/2)-180.5,len=nrow(oct94)),

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

I have carried out a spatial interpolation (Kriging) using surf.gls() The contour plot looks very plausible and the image plot is o.k too. The problem is, hovever, that I need the vectorized isoplethes, as in contour(). Unfortunately, I found no solution to get the internal data from contour(). Is there a possibility to extract contour lines as x-y-polygon from a grid without hacking plot3d.c?

Full_Name: Dominik Heide Version: 2.3.1 OS: Linux (Suse 9.3) Submission from: (NULL) (134.76.220.200) The contour functions has sommewhere (I think in .../main/plot3d.c) a maximum number of line segments that is set using a define. The contour line in my data too long for this and therefore not correct analysed (I get the message 'contour(): circular/long seglist -- bug.report()!').

First time user, so sorry if I don't understand protocol.. Anyway, I have created a data frame consisting of pearson's R values at various x and y coordinates and then plotted this using filled.contour. My data is similar to fMRI data except that it is a surface map reconstructed from histological sections. I like the results but would like to know how contours were detected. Google search

I am struggling with a contour plot. I want to place a cross over the minimum. alas, I don't seem to be able to map axes appropriately. here is what I mean: N <- 1000 rm <- rnorm(N, mean=0.0, sd=0.4) rx <- rnorm(N, mean=0.0, sd=0.4) rt <- rnorm(N, mean=0.0, sd=0.4) exploss <- function(hdgM,hdgX) { ## this could be any function that is not vectorized losscosts <-

The following example just "hangs", i.e. the final contour() does not terminate. x <- pi*(0.5+((-13):12))/36 w <- 0.377*cos(2*x)*sqrt(abs(cos(2*x))) v <- c(rep(-1.47,13),rep(1.722,13))*abs(sin(x))^1.5 cr <- outer(w,w)+outer(v,v) s <- sqrt(diag(cr)) cr <- cr/outer(s,s) contour(cr[1:26,26:1],levels=seq(-1,1,0.1),axes=T) --please do not edit the information below--

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 #~~~~~~~~~~~~~~~~~~~

Hello, I'd like to remove color bar from "filled.contour" plot. Is it possible and how? I also want to overlay "contour" plot on filled.contour but due to scaling of the "filled.contour" to account for the color bar, aspect ratio for "contour" is different from "filled.contour". Can this problem be solved? Thanks, Mark

Hi, I've used the Mathematica to produce 3D graphics, contour plots of a bivariate normal distribution Now I want make these graphics in R, but i do not know how. I would like to: - Plot a 3D graph for some different variance matrix - Plot the contour plots - Find and try to plot (in the 3d graph ou contour plot) the (1-a)% confidence region based in a chi-square(a) with the degrees of
