I'm a newbie, so please forgive me: I have a data frame that includes two long columns of x and y coordinate values thusly: ... ... ... x y ... ... ... ... ... 115 127 ... ... ... ... ... 120 129 ... ... ... ... ... 0 0 ... ... ... ... ... 135 162 .... ... ect... i need to ask R tell me how many x-y pairs contain coords that are

Hi there, I found one reference to add a reactangle behind a plot using plot(...,add=T), I tried this but didn't obtain the desired result. If a I have the following code: plot(x,y) rect(xleft, ybottom, xright,ytop,col='green) The rectangle appear on top of the plot. Any help will be greatly appreciated, Judith

Dear all, Within a larger script I use the following code to produce barplots for all variables contained in a dataframe "type3m": for(xn in names(type3m)) barplot(table(type3m[[xn]]), main = paste ("Barplot of", xn), width=0.75,legend.text=barnamesm, xlim=c(0,4),ylim=c(0,400)) The plots are produced and printed into a *.ps file. However, R gives an error

Hi all, I am looking for a clever way to create the following graph using R: I got information on the shares of some subgroups over time (summing up to 1 in each year). The graph I want to create should display the development of the individual shares over time by shading rectangulars for each share in a different color. Is there a clever of doing this? Thanks for your help Stefan

In lattice version 0.14-11 (2006/10/23), there appears to be a small bug in lrect [lattice]: border is set to NULL accidentally. It is easily fixed by adding one line to lrect -- see example and hack below ... I wasn't sure if this should be submitted as an R bug since it is part of a package, but a core/recommended package ... Ben Bolker x = runif(100) y = runif(100) my.lrect <-

Hello I am using lattice dotplot and I would like to put the strip under the panel. I found the code “strip” is for the strip above the panel, and “strip.left” for the strip left to the panel. Please kindly advise how to write the code for the strip under the panel Thank you Elaine [[alternative HTML version deleted]]

Hi, I am looking for options to plot the following type of matrices: "A" "B" "C" "D" "A" "A" "C" "C" "A" "A" "A" "C" as a image like this: http://www.phaget4.org/R/image002.jpg

Dear all, I am struggling to modify the axis labels/ticks in a panel provided to xyplot. To begin with, I do not know the equivalent of the xaxt="n" directive for panels that would set the stage for no default x axis being drawn. My goal is to draw ticks and custom formatted labels at certain hours of the week. When I execute the code below, I get an error message in the plot window that

Hi, I'm trying to construct a legend which has four lines of text and associated symbols. The first two symbols need to be normal lines which vary only in colour. The second two symbols should have filled boxes. How do I suppress the fill boxes in the first two lines? J.

If the other answers don't solve your problem, you should give us some context. Not all graphics functions in R can handle transparency, so please show us some reproducible

Hi all i need to put on one graph 2 functions who's x axis is the same and y not. I mean on horizontal the time, and on vertical left: pressure, on vertical right: rpm of a motor, is R able to do that? i've found this that i could adapt maybe (i don't need time series really?) :/ : (http://tolstoy.newcastle.edu.au/R/help/04/03/1456.html) ## ## Description: A simple function which

Dear list Is there any way that I can color the background (not the plotted points) of each box in "pairs" ? I'd like to color them according to the correlation coefficiency of each data pair. thanks. N

Dear all, Here is a simplified version of a function I made: ############ plotfunc<-function(x){ #x a vector cat("please select two points","\n") plot(x) points<-locator(2) return(points) } ############ Using R version 1.01 for mac os x (aqua GUI) I would like to know what should I do to make sure that my text line will be printed prior to the drawing of the plot.

Colleagues OS 10.5 R: 2.10.1 I have a simple x-y plot for which I would like to shade the lower (or upper) part of the interior region (i.e., the area bounded by the axes). If the delineation between top and bottom were linear, it would be use to use the polygon function. However, the delineation is a curve (which I can describe by an equation). In theory, I could divide the x-axis into a

Is there a way to create a 'bubble plot' in R? For example, if we define the following data frame containing the level of y observed for 5 patients at three time points: time<-c(rep('time 1',5),rep('time 2',5),rep('time 3',5))

Hi, I'm trying to draw a 2D plot using multiple tints of red. The (simplified) setup is the following: || year | x | y || My idea is that each year is plotted with a different tint of red. Older year (lightest) -> Later year (darkest). I've managed to plot this with different scales of grays simply by doing: palette(gray(length(years):0/length(years))) before the plot and for each

Hi, Please advice on what type of graph can be used to display the following data set. I have the following: Name Class a Class 1 a Class4 b Class2 b Class1 d Class3 d Class5 e Class4 e Class2 So each entry in name can belong to more than one class. I want to represent the data as to see where
