good morning to the R-help list!, I would like to ask if there is an alternative to the S ploting parameter "cxy" in R. I am trying to port some S code to R that makes use of this "cxy" parameter to scale the graphics, and I don't find this parameter in help(par). thank you, IOsu ------------------------------------------------------------------------------- Jes?s

I often use something like old.par <- par(set someting) on.exit(par(old.par)) but in R 1.7.0. I now get warnings: > old.par <- par() > par(old.par) Warning messages: 1: parameter "cin" can't be set in: par(args) 2: parameter "cra" can't be set in: par(args) 3: parameter "csi" can't be set in: par(args) 4:

I would like to draw only the ticks of an axis, but not the axis itself. I don't think this can be done using axis(), so I am trying to write a cut-down version in R, which only draws ticks. The point at which I am stuck is that the length of a tick is set by par("tcl") as a fraction of the "height of a line of text". So I would like to draw a line whose length is also

Here are another three problems with logarithmic scales: 1) segments() does not work with logarithmic scales. I suggest to change lines 962-973 in "plot.c": for (i = 0; i < n; i++) { if (FINITE(xt(x0[i%nx0])) && FINITE(yt(y0[i%ny0])) && FINITE(xt(x1[i%nx1])) && FINITE(yt(y1[i%ny1]))) { GP->col = INTEGER(col)[i % ncol];

Dear R-users, I am using R version 2.10.1 under windows. In a barplot, I want to mark one of the bars with a special border color. For example: barplot(c(3, 7, 11), border = c(NA, "red", NA)) But how to do this when the bars are stacked? for example: barplot(matrix(1:6, ncol=3)) # border of second bar (i.e. the one with total height = 7) should be red again, I try: barplot(matrix(1:6,

Hi I want to draw sth in a pdf file with a predefined defined size. Say a 5cm x 3cm rectangle (a ruler): pdf("rect.pdf", paper="a4") plot(c(1,5,5,1,1),c(1,1,3,3,1),asp=1,axes="n") dev.off() but how do I fix that one unit is 1cm? Thanks thomas

--==_Exmh_1801894504P Content-Type: text/plain; charset=us-ascii Dear R folks, Initially I had a plotting routine using logarithmic y-axes that failed after repeated calls if I tried to restore the graphical parameters (which I wanted to do because I used `layout' within the routine. I tried to isolate the problem and found out that the following code with logarithmic axis is sufficient for

Hi, I was hoping someone could help me with this problem. I’m trying to produce what can be referred to as L’Abbe plots, where a character (my preference is a circle) is plotted at some specified co-ordinates and the size of the character is proportional to a weighting variable. I’ve tried this plot (x, y, type="n") size <- weight/mean(weight) for ( i in 1:length(x) ) { points

Dear R-helpers, I'd like to be able to post-process contours coming from contour(). Does anyone have a version of contour() (or something similar) which will return the contour coordinates? In searching the archives I've come across a message in Nov 01 which had this on a wish-list, but I can find no later reference. With thanks, John Field Adelaide, South Australia

Hi, In the getGraphicsEvent function the (x,y) co-ordinates returned from the mouse move are in relation to where the mouse is located within the device window (i.e. the lower left corner of the window is '(0,0)', the upper right is '(1,1)'). Is there a way of returning the (x,y) co-ordinates of data points plotted where instead of x and y being the actual data points they are

I have the following data from an image analysis program, in which the x and y co-ordinates are locations of the centroids of shapes on a 2 dimensional plot. The Y co-ordinates were positive, but I changed them to negative as the resulting scatterplot was upside down (the image analysis program reads from the top of the image to the bottom, so it seems) I now need these as point pattern data, as I

Hi there, I hope to draw a plot like this: http://www.sg-chem.net/swizard/Ru-bqdi-spectra.gif is it possible to draw it using R? thanks for any suggestions. regards, Jinsong

Hi, I have a plot and I would like to overlay a PNG image over it. I'm using the rasterImage function to do this, but the problem I'm facing is working out the coordinates of the upper right corner of the final image in user coordinates. That is I can place the image so the lower left is located at the bottom of the y-axis and the left end of the x-axis. Since my image is say 100px x

Hello I am trying to input some co-ordinate sets into R of the form x,y by using lists. The command I am using is: p1 <- list(x=c(3445,563,646), y=c(234,567,456)) However the actual co-ordinate sets that I am trying to input have 305 points each and I think that the program will not accept a command that is as long as necessary. Is this so? If this is the case can you tell me how to read

Hi all I am trying to determine the distances between two datasets of x and y points. The number of points in dataset One is very small i.e. perhaps 5-10. The number of points in dataset Two is likely to be very large i.e. 20,000-30,000. My initial approach was to append the first dataset to the second and then carry out the calculation: dists <- as.matrix(dist(gis data from 2 * datasets))

Hi R users I am trying to create a spatial join between two datasets. The first data set is large and contains descriptive data including x and y co-ordinates. The second dataset is small and has been selected spatially. The only data contained within the second dataset is the x and y coordinates only i.e. no descriptive data. The aim of a join made between the two datasets is to select

Hi everyone, Can I suggest an additional output component in cancor, from package mva? It would be useful to have the number of canonical correlation vectors, equivalently the rank of the covariance between x and y (label "rank"). This would usually be min(dx, dy), where dx and dy have already been computed for the svd function, but there might be situations where it was less than

Another naive stats question. I'm trying to better understand what boxplots are telling me. I think what I see is the median and the boundaries of the 1st and 3rd quartiles. The whiskers represent the range of the data unless there are points which are outside "range" (default: 1.5) times the distance from the median to that quartile. Is that right? I've read the

Howdy! I need to calculate partial correlations and I just can't find out how to do that with R. Can anybody help?

Hey LLVM-dev, We propose to build the CSI framework to provide a comprehensive suite of compiler-inserted instrumentation hooks that dynamic-analysis tools can use to observe and investigate program runtime behavior. Traditionally, tools based on compiler instrumentation would each separately modify the compiler to insert their own instrumentation. In contrast, CSI inserts a standard
