Dear R users; Is there any way to intersect a filled contour image and a polygon? My problem is that I want to create a kriging map and the boundaries of my map are given by the coordinates of the polygon. So far I can superompose the polygon in the filled.contour image but I don't know how to get rid of the contour image outside of the polygon boundaries. Any hint will be appreciated PM

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 R-Help, I would like to make filled contour maps of ocean data overlaid by costlines from the map package. I can draw the filled contours and the coastlines om the same plot, but the filled contour also covers part of the land. To get rid of that I tried to draw a filled coastline map on top of the filled contour, but the filled map only draws the closed contours - so most of the land is

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

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 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",

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, I thought about this but programming it seems rather difficult so I was wondering if a function exists for this in R (as most of the times it turns out that it does): I have a map (shapefile) and for about 50 points on that map (GPS locations) I have heights. Is there a function which can make a perspective plot or contour plot or the like from this little data? Or maybe some function I can

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 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

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

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)

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

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)

The filled.contour function gives me some strange output. What did I do wrong? x=seq(0,1,length=10) y=seq(0,1,length=10) z=array(rnorm(100),dim=c(10,10)) filled.contour(x,y,z) lines(0.4,0.8,type="p") abline(v=0.4,lty="dashed") the x-cooridnate of the line and the point is 0.4, but it's slightly above. This problem just appears with "filled.contour", so I guess

I was trying to add points to filled.contour plots, but the points(...) function apparently uses a different coordinate system than the filled.contour(...) function; it appears that points(...) paints points where they would be if the contours were stretched over the whole plotting frame including the legend bar. Am I missing something or is it a "misalignment" in the code? BTW, I have

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

Hi, I have not been able to find answers to these questions in the FAQs, manuals, or R-help archives. If answers are available somewhere, please direct me to them. 1.) Is there a way to convert a table (e.g. represented as a data frame) to a function, specifying which columns are input and which column is output? It would seem that this would be useful for plotting experimental results,
