similar to: Contour Plot Aspect Ratio

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, I am gradually moving from the classical R plot functions to the library Lattice I have some questions about contourplot () and its arguments: 1/ I am working on geographical coordinates which makes necessary that the X (longitude) and Y (latitude) units be represented with the same distance on screen. This was obtained in the classical R plots with plot.default(x,y, asp=1,...) and then

Buenas, Quiero hacer una ingesta de datos en una base de datos de un servidor. El proceso es hacer una consulta en la base de datos, que me dice uqe columnas tengo que coger. Una vez hecha dicha consulta, abrir un csv, coger las columnas que me indicaba esa base de datos y subir el dato concreto del csv a una base de datos. Estoy pensando en usar Apache Flume o similar, pero es en un servidor

Dear all, I'm puzzled by the behavior of stringHeight in the grid package. Consider the following test, library(grid) test <- function(lab="dog", ...){ g1 <- textGrob(lab) g2 <- rectGrob(height=grobHeight(g1), width=grobWidth(g1)) gg <- gTree(children=gList(g1,g2), ...) print(c("height:", convertUnit(stringHeight(lab), "mm",

I have trying to figure this out all day so hopefully the answer isn't too obvious. I am able to view a graph in the viewer window. However, I need to export graph outside of the viewer window. Here is the script I am using: > png("Compare.png") > plot(compare$DepthSLI, compare$DischargeSLI, col="blue", xlab = "Average Water Depth (cm)", ylab =

Hello, I'm having a bit of a problem with a plot, and I'm hoping that someone might be able to help. I'm running the R Cocoa Gui v1.12 on OS X 10.4.2, and I'm doing a stacked bar plot. The plot itself is quite simple: barplot(as.matrix(s.strats.in),main="Strategy when strong", col=strat.col) where s.strats.in is a matrix with a number of rows that define the height

Hey all, I came across a security news article, referenced by http://www.linux.org/news, at http://www.techworld.com/security/news/index.cfm?NewsID=3668 talking about an SSH weakness involving the known_hosts file. I apologize if this issue has already been addressed, but the mailing list archives didn't turn up anything when i tried searching for something relevant. So; not to knee-jerk or

Hi, I need to produce an ordinary scatter plot and it is vital that the aspect ratio equals 1. I set the axis as: plot(x, y, type="n", asp=1, ,ylim=c(-80,70),xlim=c(0,100)). The problem is that I get some 'additional' blank plot area (basically, the lower bound of xlim becomes quite negative). The xlim is not the range of the x-data, but I need the 0 there for further

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 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,

Dear all, I wonder about what could actually be possible with the function "contour": 1/ - the definition of contour lines is most often meaningless when the contours are drawn in areas where no real data points exist. It can however happen that irregular distributions lead to more or less irregular clouds of data points. Interpolations (eg: loess regression, GLM, etc...) are however

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,

Hi, one of the nice things about contour is that it labels all contour lines. contourplot only labels each particular elevation a single time. i.e., if there are two contour lines corresponding to z = 45, it will only label one of them. is there a way to get contourplot to automatically label all the contour lines, even those that are repeated? i ask because i want to plot contour plots *w/

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

I am searching for a utility in R which will determine the mean location of a closed contour and eventually record the location in an ASCII file. By means of the contour utility in R, I am able to produce an image of a contour, but I am seeking a procedure which will produce the coordinates of the center of mass of the contour. From my actual set of data, the contour utility will produce several

To everyone, Is there a way to extract coordinates or an equation from a "straight" contour line? Thanks. Cheers Julius Tesoro

Hi, I would like to add contour lines to a (trellis/lattice-) levelplot. Sure, there is the "contour=TRUE" argument, but this uses "cuts=..." (which is usually chosen very high for my plots. I guess cuts=99 is the best you can do (?)) for plotting the contour lines. Furthermore, I do not like the numbering of the contour lines this way. Therefore, I tried to add a

Hello, I would like to make a contourplot of the following data; > x <- 1:10 > y <- 1:10 > z <- 100:110 By doing >contour(x,y,z) I get the following error; "Error in contour.default(x, y, z) : no proper `z' matrix specified" How do I fix this??
