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:

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, I created a 3d surface (persp) with some points overlaid on it, which is fine. Now I have a second set of z-values(x,y-values same as the first surface), which I would like to make visible on the same graph, however, not as a surface, but rather as coloured contour on the first surface, so that the resulting graph will consist of the original surface having the colour of the second

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,

I'm fitting data from a mixture experiment, and I'd like to present the results in a ternary graph with contours. I found this code by Walmes Zeviani http://n4.nabble.com/Triangular-filled-contour-plot-td1557386.html which is just what I want--except I would like the axis titles and labels to be proportionately larger than the ternary graph itself, for legibility in publication. When I

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 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

I would like to plot some lat-lon data in a filled contour, and then overlay a map of the globe on top. I am trying something like this: filled.contour(lons, lats, glb.data, plot.axes={axis(1);axis(2);map(projection='rectangular',parameters=0,add =T)} ) The filled contour plots fine, and the map shows up, but only as a very tiny little black rectangle in a small area of the

Hi, Splus allows pasting a graphics object into the plotting window, which makes it possible to do what you describe below. Now I use R which doesn't seem to allow pasting the picture into the graphics window, so I copy the graph onto a transparency sheet, and stick it onto my screen using tape. The coordinates need to be converted to make sense (as you describe). My methodology with the

Dear R-Help community, I am trying to overlay a single contour line over a correlation plot using levelplot in the lattice package. These are the two arrays: 1) a correlation plot over Africa - so each grid square is a different colour dependent on correlation - this is in an array: result_cor with dim[465,465] 2) a single contour line from a ***different data source*** - this is from data

Hello there, I am creating a series of images using levelplot but I also want to overlay a contour for a particular value as reference. Here is the levelplot command for the image: print(levelplot(d~x+y,data=t,cuts=20,scales=list(draw=F),xlab=NULL,ylab= NULL,col.regions=heat.colors(100)[100:1]),split=c(1,1,1,1),more=T) and then to add the contour plot (I only want a contour at level 5):

Dear Community, (win XP home, sp1; R1.7 -- patched version, binary download, version of lattice obtained with patched version; the following applies to 1.6.2 as well.) The following message was originally composed to seek help. However I have 'hacked' a solution to the following behavior, but none the less someone might find this interesting. To reproduce my 'problem' you

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

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

Hello, when I tried to create 3D graph from attached file (at first: columns 1, 2, and 3 (longitude, latitude, altitude), then columns 1, 2 and 4 , then the same for column 5 etc) using Akima library for 3D interpolation (the data are neither equidistant nor regularly distributed), the console crashed by SIGABRT fault response. Do you know what is the main problem? Otherwise, can you advise me the

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)),

I apologize for what may be a newbie question: I have two sets of data, one is X,Y,Z data that I'd like to make a contour plot of (Z defining the contours), and a second set of X,Y data (Y as a function of X) which I would like made into a line plot OVERLAYED on the contour plot (X and Y from both plots are in the same units and will have overlapping values). Any suggestions on how to do this

Hi everyone, I hope this question is beyond "read the manual". My task is simple, just to plot the following, but the plot in the middle should be a filled.contour plot: http://gallery.r-enthusiasts.com/graph/Scatterplot_with_marginal_histograms_78 Background: I prefer filled.contour rather than hist2d. Because, I could use kernel smooth, so the plot for discrete data won't be too

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

Dear All, I tried to plot contour lines using R function contour, but got the results which are not expected. require(RTOMO) x <- seq(-1,1,0.1) y <- seq(-1,1,0.1) xy <- meshgrid(x,y) z <- xy$x^2+ 3*xy$y^2 contour(x,y,z,col="blue",xlab="x",ylab="y") The above code gave me the contour graph for z=3*x^2+y^2 rather than z=x^2+3*y^2. Is anyone know the
