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

Hello All! How to plot a image ( image function ) with restrictions, like a polygon?? Thanks in advance! Cleber N.

...llo 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) axis(2,1:length(yy),labels=ylabels) }) which results in the figure attached. Overall the figure looks great. However, my 2 question are: 1) how can I make sure that the contour lines match the shading? you can see from...

...ot;) The new script would be: contour.default<- function (x = seq(0, 1, len = nrow(z)), y = seq(0, 1, len = ncol(z)),z, nlevels = 10, levels = pretty(zlim, nlevels), labels = NULL, xlim = range(x, finite = TRUE), ylim = range(y, finite = TRUE), zlim = range(z, finite = TRUE), labcex = 0.6, drawlabels = TRUE, method = "flattest", vfont = c("sans serif", "plain"), axes = TRUE, frame.plot = axes, col = par("fg"), lty = par("lty"), lwd = par("lwd"), add = FALSE,asp=NA,...) { if (missing(z)) { if (!missing(x)) {...

I can't seem to figure it out.? I'm not sure the bmp image can/will be posted, so maybe you can just take my word for it.? It is a gridding pattern in white, that appears over the plot area only. Vertical lines are every 4 units, evenly spaced....

...c to r-devel; it's not a Mac problem. I've also added back a bit of the context for readers here. A little bit more on this: the problem only affects contour() when labels are being drawn, and only if method is set to "flattest" (the default) or "edge". If you set drawLabels=FALSE or method="simple" you won't see it. I think I should be able to fix this after all. Duncan Murdoch

Dear all, We used the following function to create a spatial plot of a raster image: filled.contour(xx,yy,zz, color = terrain.colors, nlevels=10, main=naamjaar, plot.axes = { contour(Xcoord/1000,Ycoord/1000,lim.data, nlevels = 4, col=4,drawlabels = T, axes = FALSE, frame.plot = FFALSE, add = TRUE);axis(1); axis(2); points(fire[,2:3]/1000,col="red",pch="*",cex=2,lwd=3) }) we however would like to create 5 maps with only one legend. This seems not to be possible with...

Hi, I would like to plot a x,y curve described by the equation : Ax^2 + Bx + Cy^2 + Dy + E == 0 (A,B,C,D,E are constants) This sounds like quite the common task but haven't been able to figure out how to do this. Could you please help ? I am new to R so probably missing something basic. Thanks

Hi, I am using the lda function from the MASS library. I would to find the decision boundaries of each class and subsequently plot them. I wonder if anybody can offer any help on this topic? Below I applied the lda function on a small dataset of mine. Any help will be much appreciated. > library(MASS) >

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:
