Hi everybody. I'm a new R user and i've been searching a tool for construction of regression tree... I found function "tree()" written by a certain Mr. Ripley, and seems to be just what i'm looking for, but when i try to use it in R replies me:"Object not found". So I was wandering if I should include one special library or something like that? Thanks a lot, ana

Hallo, can someone please help me. I have a proplem reading a file with more that one rows. e.g I used the function: p<-read.table(file="FILENAME ", header=TRUE,sep=";") and later used the data.Frame() function. It functions when the file has only a row of variables. When I insert the second row I get an error message. How do I do this ===== ===================== Sylvie

Hi, If I have: foo <- survfit(y ~ x) where y is a survival object and x is a n-level factor. The documentation says when I plot(foo), the confidence intervals will not be plotted (which I guess is understandable as otherwise the plot will get really messy). I tried to plot with confidence intervals by using: plot(foo, conf.int = TRUE) and indeed the resulting plot is messy. However

Hello helpers I have this problem. When I plot a regression tree, some words are cutted in the figure. There is an attached file tree.ps to see what I'm saying.

Hi, I have a column in a dataframe in the form of: > as.vector(SLDATX[1:20]) [1] "1/6/1986" "1/17/1986" "2/2/1986" "2/4/1986" "2/4/1986" [6] "2/21/1986" "3/6/1986" "3/25/1986" "4/6/1986" "4/10/1986" [11] "4/23/1986" "4/30/1986" "5/8/1986"

Hi, I'm not sure if this can be done but.. I know that with ifelse() I can do something like: ifelse(x <= 3, 1, 2) to go through each element in my vector x, and if x_i <= 3 substitute the number with 1 else with 2. Essentially I'll get a vector with 2 levels. Can I tweak it so I can get 3-levels? For example: if(x <= 3) then 1 elseif(3 < x <= 4) then 2

Hi, I have a function foo(x,y) and a dataframe, DF, comprised of two vectors, x & w, as follows : x w 1 1 1 2 2 1 3 3 1 4 4 1 etc I would like to apply the function foo to each 'pair' within DF e.g foo(1,1), foo(2,1), foo(3,1) etc I have tried >apply(DF,foo) >apply(DF[,],foo) >apply(DF[DF$x,DF$w],foo) However, none of the above worked. Can anyone help ?

Hi, I have a very simple question. If a want to save a whole program (say more than 5 command lines), how can I proceed without each time using the command history (that allow me to recall previously saved command, but which is to long if you want to recall more than 5 command lines), or without saving to a text file and use copy/paste when I open a new R session (but in fact this doesn't

Hi, I'm doing a presentation on Neural Networks and Tree-Based Models in two weeks, at the moment I'm looking for a data set to use in the presentation. What I would like to use is a good old data, like the Iris data, that is already known by every statisticians. MASS4 uses the cpus data in Chapter 8.10 and the Cushing's syndrome in Chapter 12.4. These two data sets plus the

Dear helper. I am a beginer. I have difficulties to handle axis. I want to draw axis label such that axis has range of [-0.4,0.4] with intervel 0.2 for x and y axis. Some part of range do not have data points. Thus, plot does not show whole range. How can I enforce plot to depict the whole range regardless of existence of data points ? Another problem is that when I depict axis labels, some
