similar to: filled.contour with log axis

Dear all, as you can see from the code I want to create *a panel of 11 contour plots through a iteration process*. I found a thread that address the issue of plotting many contour.plots in the same device, but it does not address my problem! I emphasize that the 11 contour plots must be appeared in the same device through an iteration process and NOT individually! par(mfrow=c(4,3)) # I want them

Dear all, I am using filled.contour and my x-axis consists of a vector of dates, formatted using as.POSIXct. When I assign this vector to x in filled.contour, the x-axis in the plot is correctly formatted as dates. However, when I use plot.axes=axis(1) in filled.contour the x-axis is not correctly formatted. I need to opt for the latter because I want to add additional lines and points to the

How do you label Xtick and Ytick marks with Currency symbols: $2000 instead of 2000? I would like to add dollar symbols to tickmarks on boxplots, histograms and back-to-back histograms. My Examples (requiring the lattice and Hmisc packages): data(case0102, package="Sleuth2") str(case0102) boxplot(Salary~Sex, case0102) histogram(~ Salary | Sex, data=case0102) require(Hmisc) #

Dear All, I was looking for the color index in?image function,?such as from topo.colors(n) and etc. but still never found it. For instance, from the help menu. ########################################### # Volcano data visualized as matrix. Need to transpose and flip # matrix horizontally. image(t(volcano)[ncol(volcano):1,]) # A prettier display of the volcano x <- 10*(1:nrow(volcano)) y

hi dear R crew. may i request the script for volcano plot. if able, pls include any tips about volcano plot. thank you. [[alternative HTML version deleted]]

Do you know what steps I need to take to add a scale to a plot? I'm pulling my example out of "An Introduction to R: Software for StatisticalModelling & Computing" (see the R code around Figure 76). I would like to add a scale to the image produced by the following code.? I would like to the scale to list the distance?and units:? data(volcano) x <- 10*(1:nrow(volcano)) y

can you recommend a good manual for R that starts with a data set and gives demonstrations on what can be done using R? I downloadedR Langauage definition and An introduction to R but haven't found them overly useful. I'd really like to be able to follow some tutorials using a dataset or many datasets. The datasets I have available on R are Data sets in package 'datasets':

When I try to plot two lines ( or scatterplots) with different scales, this is what I have been doing: Suppose: I have y1 and y2 in a very different scale y1 = 1:100 y2 = c(100:1)*10 To plot them on top of each other and denote by different colors: I have to figure out the correct scale '10' and corresponding tick.vector and lables. Then do: plot(1:100, y1) # I can have

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

Hi! Whenever I save a graphic in ps/eps format generated by filled.contour or image, an undesired grid is added to it (not visible on the X11 screen). For example: postscript("volcano.eps") filled.contour(volcano,col=gray(seq(0,1,,50)),levels=seq(min(volcano),max(volcano),,50)) dev.off() Any ideia how to eliminate this grid? Thanks, Rachel [[alternative HTML version deleted]]

Hello, I am drawing contour lines for a function of 2 variables at one level of the value of the function and want to include a small arrow in any direction of increase of the function. Is there some way to do that? Below is an example that creates the contour lines. How do I add one small arrow on each line in the direction of increase of the function (at some central point of the contour

Quick question - I am having problems creating an orographic image (similar to volcano example). I have created a map matrix with 3 columns and over 2million rows. I have created the matrix as follows: map<-read.table("map.dat",header=TRUE) long.grid<-sort(unique(map$long) lat.grid<-sort(unique(map$lat) map.matrix<-matrix(map$height,nrow=length(lat.grid),byrow=TRUE) The

Hi everyone. I am new to R. It will be greatly appreciated if someone can help me with the following questions. Here's the graph I have just produced. http://www.nabble.com/file/p24732839/calibration.jpeg (1) How can I put the legend on top of the grid lines? (2) How can I match the grid lines with the x-axis ticks? (3) How can I change the x-axis format from e.g. Mar, Apr...etc to

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

Thank you sir for your prompt reply. Currently i am stuck at point where I need to call an available Matlab program from an R 2.4.0 interface. How can I do this? I have downloaded the R.matlab file and also the manual in pdf. But still i am not able to get through the problem. I will be grateful to you if you can elaborate me on this. Awaiting your reply, regards, Bhanu Kalyan K

Hello everybody, Could anybody give me a hint how I can use "layout" and "filled.contour" (or "image" plot with a color legend) together, please? What I want to do is something like the following example (Two or more plots with a legend for each at one page): data(volcano) layout(matrix(1:2, 1, 2, byrow = TRUE)) for (i in 1:2) { filled.contour(i*volcano, color =

Is it possible to change the color/thickness of the summary line in an interaction.plot without changing the other individual data lines? I would like to make the line from the summary function (mean) the color red and thicker than the surrounding black lines. How can I do that? Here is a link to interaction.plot: http://stat.ethz.ch/R-manual/R-patched/library/stats/html/interaction.plot.html

I am trying to create a topographic map of an island - the filled.contour function works fine except i am experiencing difficulty trying to represent the sea properly. Basically I want the default colour blue for any instance where z=0, if I simply use the default topo.color I get shades of blue for z values up to 220 metres. Is there a way in which I can specify terrain.color for all values of

Hi all, I am using the zoo package to plot time series. I have a problem with formatting the axes. my zoo object (z) looks like the following. c1 1992-01-10 21 1992-01-17 34 1992-01-24 33 1992-01-31 41 1992-02-07 39 1992-02-14 38 1992-02-21 37 1992-02-28 28 1992-03-06 33 1992-03-13 40
