Hello, I am trying to print graphs using R on MS windows by clicking on the option Print on the top of the window, the surprise...I don't get the graph, but the text, I think asci, that generate the graph, about 20 pages what is the problems.... Please.... any help is appreciated, thank you so much halima =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= r-help

Dear R-users It is me again with my interminables questions... This time it is about "pictex". I understood that pictex allows us to put our graph in a latex file I have try the function: > pictex (file=...) and the answer was: "pictex" not found... Does it mean that it is not an R-function yet? Thank you for any feedback. Halima from Leiden

Hello everybody, I am doing a plot and I would like to know which parameter I have to use in order to get an equal scale for the axes x and y: Means, if the intervals in the x-axis is 0,5,10,15.... I would like to have the same scale for the y-axis. Thank you so much for your help. Halima from Leiden where the sun is shining. Holland

Hello R users, This question might be already discussed before, I apologize if it is the case. Simple... how can I do to include a figure in a latex document. As I have already done in Splus, I tried this: \begin{figure} \special{psfile=gauss.ps .......} \end{figure} but it didn't work. Any help? Thank you in advance. PS: I let down the Mac and the MS Window platforms and I am back to my

Dear R-users I am introducing my collegue to R and she is interested to use R to perform Polytomous Logistic Regression called also Multi-category logistic regression. Is there any program in R doing this? Thank you so much for any feedback. I take this opportunity to thank people who were kind to answer my query about how to include a postscript file generated from R, in a latex file and

Hello, Is there anyone using R in the Mac? If yes, my question is so simple. I have just started to use R ( I am a user of the Mac) and I would like to analyse a data, on a directory in my Mac, using R. How can I do to bring the data file to use it in R. I have tried like Splus, the function: mydata<-matrix(scan("data"),nrow=...,ncol=....) but it doesn't work. Thanks Halima

Hello again, Since it was very efficient to ask people of r-help about reading a file in R from Mac, and I thank them all. It gives me the courage to ask another question. I get use in Splus(unix) to write a function using the editor emacs, a small function called emacs() helped me to open at anytime an emacs window in Splus to open a function, change it, add something on it.... Now my problem

hello, I have been using R for few months now, it seems very helpful even on Macintosh ;-), but there are some functions I don't find. For example, I am ploting some histograms and I would like to put over the hist, the curve of the distribution of my data. If my memory is right, in Splus it could be done by using the function "density", I looked at R manual and find the function

Hello, I'd like to thank the people who replied to my query about the Plot and scale. I tried all the propositions and they works fine, but the one I liked and that worked very well is the Brian Ripley's function that our dear Vill Venables from Australia send me. If someone needs to use this function and with the permission of Vill, I can send it to him/her. It works very well. Thanks

I suggest a simple enhancement to segments() and arrows() to facilitate drawing horizontal and vertical segments -- set default values for the second x and y arguments equal to the first set. This is handy, especially when the expressions for coordinates are long. Compare: Segments: < function (x0, y0, x1 = x0, y1 = y0, col = par("fg"), lty = par("lty"), --- > function

Greetings R world, I know some version of the this question has been asked before, but i need to save the output of a loop into a data frame to eventually be written to a postgres data base with dbWriteTable. Some background. I have developed classifications models to help identify problem accounts. The logic is this, if the model classifies the record as including variable X and it turns out

I have a dataframe that looks like this: > str(chr) 'data.frame': 84 obs. of 7 variables: $ county: Factor w/ 3 levels "Broome","Nassau",..: 3 3 3 3 3 3 3 3 3 3 ... $ item : Factor w/ 28 levels "Access to healthy foods",..: 21 19 20 18 16 3 2 6 17 8 ... $ value : num 8644 15 3.5 3.9 7.7 ... $ low : num 7897 9 2.5 2.6 7 ... $ high : num 9390

Dear all, I am trying to get an estimate of uncertainty surrounding a single predicted value from a beta regression model (this is similar to a logistic glm - in that it involves a link function and linear predictor - but it uses the beta distribution rather than discrete binomial). For example: library(betareg) data("GasolineYield")

Hello I want to build a classification tree for a binary response variable while the condition for the final tree should be : The total misclassification for each group (zero or one) will be less then 10% . for example: if I have in the root 100 observations, 90 from group 0 and 10 from group 1, I want that in the final tree a maximum of 9 and 1 observations out of group 0 and 1, respectively,

I use sieve-filter for postprocessing misclassified mail. For false positives I use the following script: require [ "variables", "include", "fileinto" ]; global [ "FORCENOSPAM", "ext", "ext1" ]; set "FORCENOSPAM" "YES"; fileinto "JUNK-PRENOUCE"; if header :matches "Delivered-To"

Hello, I am plotting many histograms together using facet_grid in ggplot2. However, I want to then add a vertical line to each histogram, or facet, each of which vertical lines are at different x-values. The following example adds all vertical lines to each facet: ggplot(data,aes(values)) + geom_histogram() + facet_grid(.~variable) + geom_vline(xintercept=c(5,10,15)) How can I add a vertical

Hi, I am trying to add a vertical arrow (from top to bottom or from bottom to up) to a time series plot using ggplot2 and xts. It seems that the vertical line command "geom_vline" does not work for this purpose (Correct me if I am wrong). I try the command "geom_segment" as follows, but I got an error message at the last line "Error: Invalid input: date_trans works

I don''t know if HAML questions are appropriate here ... but here goes. How does on end line to be rendered with a vertical bar (|) ? The vertical bar is a line continuation, aparently. Doing \| cause the vertical bar to be emitted ... as well as the backslash. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups

Dear R helpers I would like to plot vertical reference lines for yearly averages the variable being plotted. In this case there are three years 2002, 2009 and 2010 for a variable Resc_Gt. I've attempted to get the 2002 mean plotting (2.27) using the 'abline' command but no joy. Ideally I would like to be able to compute and plot the means of the three years automatically using a
