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 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

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 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, 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

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

I want to use question numbers from my survey data (fake data below) as markers in a scatterplot. I'm using "as.character" to convert question numbers to characters. However, plot truncates the 0 (zero) off of question 10. How can I get the ending zero so I can add questions 11 - 20? # Sample code below Question <- c(1,2,3,4,5,6,7,8,9,10) Performance <-

Hi, there, Suppose I have two vector say x=c(1 2 3 4 5) and y=(2 3 6 7). Then I want to combine these two vector together and get z=c(1 2 3 4 5 6 7) with 2 and 3 only appear once. I want to extend this one to a general case(say more than 100 elements in x and y and each time I don't know which elements are the same). Do you happen to know how to do this and which command should use? Thank

Hi. I can quickly create a by object that selects rows from a data frame. After that, though, I don't know how to merge the rows back into a data frame that I can use. Here is an example where there is a data frame with three columns, a, b, and c. I update it so that there are two rows for each combination of a and b. I use by to select the subgroups of rows that share the same a and b

Hello, I run R on Windows 2000. When I load lattice library and plot some lme class objects, the graphic window displays a dark-green color. Graphics look ok on the screen, but lines and points become invisible whem I send the plot to a printer because of the background color. Are there ways to reset the background color? Both par(bg=) and windows() do not work. Any ideas? Richard

I have a small problem. I am running glm() in R-0.61.0 on Redhat 4.2. I want to get the standard errors from the output. If I do out <- glm(....) summary(out) I get the coefficients printed as well as their correlation matrix. If I do out$coefficients I get the coefficients out$fitted gives me the fitted values I can then assign the fitted values or the value of the estimated

Hello Spse I have a matrix, say 1 2 3 4 5 6 7 8 9 and I would like to expand it by repeating rows within the matrix, to get, if the repeating factor is 2, say: 123 123 456 456 789 789 (or columnwise as well) . There must be a smart way of doing that? Many thanks Juhana Vartiainen juhana.vartiainen at labour.fi -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-

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, I need to draw a vertical line on my plot, the uncertainty segment (which is a vertical segment on every point of my plot so I can have an idea about the probability that a point is misclassified.... clustering problem.....) I remember I have done it a long time ago in Splus using a function called "segment" to which we give the extrem point of the segment , I didn't find

In the source code perhaps? :-) You can find a pretty precise description in the article Robert and I did in JCGS. Actually its pretty simple. Functions have access to the variables which were in effect when the function was defined. f <-

Dear Sir, How do I change the intervals on the x axis of a histogram plot; let us say for example the intervals were 0,5,10,15,and 20, and I wanted to change the intervals to 0,2,4,6,8,10,12,14,16,18,20. I look forward to receiving your words of wisdom. Ivo [[alternative HTML version deleted]]
