similar to: filled.contour and points

Dear All I would like to use filled.contour to plot something with arrows on it. I did it in this way: filled.contour(1:nx,1:nz,u,col=gray(rev((0:20/20)))) for (j in zseq ) for (i in xseq) arrows(i, j, i+u[i,j],j+w[i,j],length=angleng,angle=angarrow,code=2, lwd=1,col="black") The peoblem is that the arrows use the whole device area, including the key on the right hand side of the

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 All, I tried to draw 3 filled.contour plots on one page, but failed. It returns "Error in plot.new() : Figure margins too large". Can anyone help me to do this. BTW, does anyone has the experience to draw a isosurface with R? Dr Zhiqiang Cui School of Geography and Environmental Sciences The University of Birmingham Edgbaston, Birmingham B15 2TT

r-help, I can't seem to get the below data organized in such a manner so as to generate a contour plot using any of the functions {lattice.contourplot, base.contour, base.filled.contour}. I was wondering if anyone could please tell me what I need to do to accomplish this. X,Y,Level -31.105,86.911,3843 -3.385,86.911,3896 24.335,86.911,3874 -24.175,79.700,3900 -3.385,79.700,3927

hello everyone, I was wondering if anybody can help me solve 2 problems related to the function filled.contour. I am entering the following R command: filled.contour(xx,yy,P1, nlevels=20,color=cm.colors, plot.axes={ contour(xx,yy,P1,add=T,col="grey", nlevels=20, drawlabels=F) axis(1,1:length(xx),labels=xlabels)

Dear R-users, I haven't found a way in the searchable archive to overplot a contour (lines) over a surface. I have a (n,m) matrix that represents sea surface temperature that I have plotted using image.plot(), filled.contour() or image(). I would like to overplot this image with some contour lines of mixed layer depth values(same size matrix). How can I do this? Any help is appreciated,

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:

Hello, I'm having some trouble getting things to look as I want with filled.contour. 1. My first issue is that I am unable to add line segments to my plot where I want them. Using the rug pattern example: x <- y <- seq(-4*pi, 4*pi, len = 27); r <- sqrt(outer(x^2, y^2, "+")); filled.contour(cos(r^2)*exp(-r/(2*pi))); segments(0.2,0.2,1,0.2); The line segment is not found in

Is it possible to create a contour plot with the isolines labeled. I know you can do this with Matlab. Argh! I tried creating a filled contour plot, then using par(new=T), followed by overlaying the contour plot on top. However, the placement of the filled contour plot and the contour plot do not align correctly. Any suggestions would be appreciated. Thanks, Jon -- View this message in

Hi. I'm a big user of level plots. Because filled.contour() didn't do exactly what I wanted, I hacked at it a bit to add these options: (*) Even spacing in the key, even if the contours are not evenly spaced. (*) Horizontal key (*) options to not use layout() and to plot only the level plot _or_ only the key. This means you can use layout yourself to (e.g.) have several

Full_Name: Marco Gruteser Version: 1.7.1 OS: Win XP Submission from: (NULL) (129.34.20.16) Let's generate a dummy filled.contour plot > x <- 1:10 > y <- 1:10 > z <- array(rep(0, times=100),dim=c(10,10)) > filled.contour(x,y,z) And try to add some points to it, e.g. > points(8,2) > points(6,2) The points show up misaligned with the axis somewhere at 9.9,2 and

Hello I have a small problem with filled contour plots. I'd like to plot point on top of that using points(). Trouble is, the x axis of the contour plot is modified to make room for the legend but points() is not aware of that. It could be easily tackled by using a linear transformation of x in points(), but does anyone know exactly *what* transformation? Kind regards Ivailo Partchev

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

Dear R-help members, I am trying to plot annotate a filled contours plot (with filled.contour) with a grid of points. I have read ways of annotating it with individual points but not with grids in another matrix. Any ideas? Thank you very much.

Dear All, I have a question on overlaying a filled.contour (e.g. on soil properties data) and contour (by elevation) in one graph. Both have the same z matrix dimension. I'm able to overlay both graph, but the plots dimension did not overlap well on the same plots. How can I have both filled.contour and contour on the same graph? The commands that I have written are as follows:

Dear R help contributors, I'd like to plot ground temperature with time on X-axis and depth on Y-axis on this datasets ( http://r.789695.n4.nabble.com/file/n3301033/NEdaily.csv NEdaily.csv ), and to do so I use the following commands: library(RSEIS) xNE <- seq(1, as.numeric(as.Date(max(NEdaily[[1]])) - as.Date(min(NEdaily[[1]]))), 1) yNE <- rev(c(-0.3, -0.5, -0.7, -0.9, -1.1,

Hi, Is there a way to make the filled.contour() function produce a plot similar to the image() function? i.e. not have smooth contours but rather distinct "squares" corresponding to the different cells of the matrix. The reason I ask is because since image doesn't have an option to display colour bars it is a lot less useful. Cheers Muri Soares Department of Maths and Applied

Dear R-helpers, I'm plotting geophysical data in the form of contours using "filled.contour". The display would be much more effective if the areas with negative values could be color coded by -- say -- "cold colors" in the range of blue to green, and conversely the areas with positive values got plotted with "warm colors", from yellow to red. Right now if I use

I am attempting to create a contour plot using R with this code: > contour <- as.matrix(read.csv("contour.csv", row.names=1, header=TRUE)) > library(gplots) > filled.contour(contour, main="Flume 1 Flow Velocities") Now this produces the image/plot that I am looking for perfectly. However, the both axes only go from 0 to 1 instead on of using the row and column

Hi R-help community, Can anyone tell me why, while using : x <- seq(as.Date("2001-01-01"),as.Date("2001-01-01") + nrow(volcano)-1,1) y <- seq(1, ncol(volcano),1) when I plot the volcano matrix with that command : filled.contour(x,y,volcano) the graph has a Date format on X-axis, ok ... ... but when adding a contour plot to the filled contour, using this
