similar to: filled.contour+graphics output

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 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,

Hola a todos: Yo pensaba que la diferencia entre contour y filled.contour radicaba, simplemente, en que la segunda pintaba con colores los espacios entre las curvas de nivel, pero haciendo lo de abajo aparecen diferencias require(gplots) celdas <- 5 m <- matrix(10,celdas,celdas) m[3,3] <- 20 m[2,2] <- 20 m[1,] <- m[celdas,] <- m[,celdas] <- m[,1] <- 20 image(m,asp=1)

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:

Is it possible to add labelled contour lines to filled.contour plot ? [[alternative HTML version deleted]]

I'm stumped, can anyone find my error in this sequence. for(j in 1:(varsize[4]-1)) temp <- get.var.ncdf(nc=input, varid="p_foraging",c(1,1,j),c(varsize[1],varsize[2],1)) filled.contour(x, y, temp, color = terrain.colors, plot.title = title(main = paste("Everglades Wood Stork Foraging Potential \nYear", (2000+j)), xlab =

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,

By any chance are there any alternatives to image(...) and filled.contour(...) I used Rseek to search for that very topic, but didn't turn over any leads... http://www.rseek.org/?cx=010923144343702598753%3Aboaz1reyxd4&newwindow=1&q=alternative+to+image+and+filled.contour&sa=Search&cof=FORID%3A11&siteurl=www.rseek.org%252F#1238 I'm sure there are some out there, but

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

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

Dear R-projects users I would like like to ask if there is any way to produce a multipanel plot with the filled.contour function. In the help information of filled contour it is said that this function is restricted to a full page display.

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)

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

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

Dear all, I can't figure out a way to have more than one plot using filled.contour() in a single plate. I tried to use layout() or par(), but the way filled.contour() is written seems to override those commands. Any suggestions would be really appreciated. Jonathan [[alternative HTML version deleted]]

By any chance is it possible to "add" filled.contour(...) to an existing plot like you can do using image(..., add = TRUE). I looked at the filed.contour(...) and levelplot(...) documentation, but it didn't seem to be possible. I would like to add filled.plot(...) as shown below instead of using the image(...). Filled.contour seems to provide the smoothing interpolation

Dear all, I would like to generate a filled.contour plot with log x and y axis, however using: filled.contour(as.line,log="xy") results in a warning message. Does anybody knos what to do? Thanks Thomas

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
