similar to: plotting rpart objects, text.rpart, fancy option

Hi all, I'm trying to create nice plots of rpart objects. In particular, I'd like to use the "fancy" option to text() that creates ellipses and rectangles at the splits and endnotes, respectively. This worked fine in the past, but now the ellipses do not interrupt the original tree lines anymore but overlay them (see attached ps file). I'd like it to look the way Figure

Dear r-help-list: If I use the rpart method like cfit<-rpart(y~.,data=data,...), what kind of tree is stored in cfit? Is it right that this tree is not pruned at all, that it is the full tree? If so, it's up to me to choose a subtree by using the printcp method. In the technical report from Atkinson and Therneau "An Introduction to recursive partitioning using the rpart

Hello again I've looked through ?rpart, Atkinson & Therneau (1997), Chap 10 of Venables and Ripley, Breman et al., and the r hgelp archives but haven't seen the answer to these two questions 1) How does rpart deal with asymmetric loss matrices? Breiman et al. suggest some possibilities, but, of course, do not say how rpart does it. 2) In the loss matrix, which direction (column or

Dear r-help, I am looking for additional documentation on the "adj" column in rpart's splits matrix. The help says: adj gives the adjusted concordance for surrogate splits I am looking info about "adjusted concordance". I cannot find this phrase in either Therneau & Atkinson original RPART documentation or the CART book. This question came up in the

Dear all, I'm writing my own method to be used in Rpart by defining the list of functions named init, split and eval. I'm following the example given in the file 'tests/usersplits.R' in the sources. By now I'm able to define the split function (and it works correctly in the tree construction) while I have some problems with the init and the eval function. The task I'm

I'm trying to plot pspline'd explanatory variables from coxph() models as per Therneau and Grambsch (Modeling Survival Data: Extending the Cox Model). They have s-plus functions for this at: http://www.mayo.edu/hsr/people/therneau/book/sfunction/gamterms.s http://www.mayo.edu/hsr/people/therneau/book/sfunction/plotterm.s I'd like to make these plots in R, but they make use of non-R

Dear useRs: I try to plot an rpart object but cannot get a nice tree structure plot. I am using plot.rpart and text.rpart (please see below) but the branches that connect the nodes overlap the text in the ellipses and rectangles. Is there a way to get a clean nice tree plot (as in the Rpart Mayo report)? I work under Windows and use R2.11.1 with rpart version 3.1-46. Thank you. Tudor ...

I would like to remove rows from the following data frame (df) if there are only two specific elements found in the df$ch character string (I want to remove rows with only "0" & "D" or "0" & "d"). Alternatively, I would like to remove rows if the first non-zero element is "D" or "d".

Hello Gurus: When I plot a survival fit using rpart for the classification tree, for each node, there is a decimal based number above the event/total. I tried to see if it's the exponential ratio or logrithmics, neither seem to be the case. I'm wondering if anyone knows what they are. Thanks, Karen _________________________________________________________________ Find hidden words,

I ran this code (several times) from the Quick-R web page ( http://www.statmethods.net/advstats/cart.html) but my cross-validation errors increase instead of decrease (same thing happens with an unrelated data set). Why does this happen? Am I doing something wrong? # Classification Tree with rpart library(rpart) # grow tree fit <- rpart(Kyphosis ~ Age + Number + Start,

When I run R CMD check on the survival package I invariably get a note: ... * checking for file ?survival/DESCRIPTION? ...

This is sufficient for the auto-check process to return the following failure message: Dear maintainer,

Hello dear R-help members, I would appreciate any help in understanding how the rpart function computes the "improve" (which is given in fit$split) when using the split='information' parameter. Thanks to Professor Atkinson help, I was able to find how this is done in the case that split='gini'. By following the explanation here:

Is there a way to include the compiled version of a vignette in the doc directory but mark it to NOT be rerun by CRAN??? I think I remember that this is possible, but have forgotton how.?? (It might even be a false memory.) Terry T. Background:? Beth Atkinson and I are splitting out many of the vignettes from the survival package into a separate package survivalVignettes.? There are a few
