Hi, Dear all R users: Does someone know whether R can calculate the Receiver Operating Characteristic (ROC) Curves? I didn't find it from the packages. Thanks a lot. --- Xin

Dear R- users and Helpers: I downloaded the package from www.stat.lsa.umich.edu/~faraway/book and installed it from local zip file. It looked fine. But when I input library(faraway) it showed " Error in library(faraway) : 'faraway' is not a valid package --- installed < 2.0.0? What I used is R 2.0.0 version now. What should I do? Thank you very much. Xin

The summary stats for the xin and yin variables below are correct. However, if I use plot(xin,yin), an exception is thrown saying that "object xin is not found." Also, it is apparent that I can't successfully replace the x and y vectors with values from xin and yin. The four plots on one panel are showing but the range of x and y is only [0,1], and therefore, it seems like an

With changeset 6869, I can _not_ start xend. Did anybody else meet the same issue?

Hi, all Our understanding of how classification trees in Rpart treat missing is that if the variable is ordinal(continous), Rpart, by default, imputes a value for missing. How do we do the classification tree and tell Rpart not to impute. That is, what command is used to turn off the imputation. Also, if we do get true missing, how does classification tree analysis in Rpart treat missing when

Hi, I am using rpart decision trees to analyze customer churn. I am finding that the decision trees created are not effective because they are not able to recognize factors that influence churn. I have created an example situation below. What do I need to do to for rpart to build a tree with the variable experience? My guess is that this would happen if rpart used the loss matrix while creating

Hello. I have a hudge problem, don't know how to deal with it... I'm supposed to implement a tree structure in R, without using rpart library... I don't have any clue about appropriate approach... Anyway, I can't use pointers under R...so how to to it? lists, vectors... Anyway, does anybody knows how the regression tree in rpart was implemented... Someone please help! Thanks, ana

From: Jan Kara via Ocfs2-devel <ocfs2-devel at oss.oracle.com> commit 90410bcf873cf05f54a32183afff0161f44f9715 upstream. When buffered write fails to copy data into underlying page cache page, ocfs2_write_end_nolock() just zeroes out and dirties the page. This can leave dirty page beyond EOF and if page writeback tries to write this page before write succeeds and expands i_size, page gets

an obvious fix to PIC IO intercept. In PIC IO, address from send_pio_req is physical address already.

Hi, There are two packages providing knn classification: class and knnTree. However, it seems both uses Eucleadian distances only. How can I uses a custom distance function with either package? Thanks, Xiao-Jun

I am trying to create a classification tree using either tree or rpart but when it comes to plotting the results the formatting I get is different than what I see in all the tutorials. What I would like to see is the XX/XX format but all I get is a weird decimal value. I was also wondering how you know which is yes and which is no in each leaf of the tree? Is yes always on the left?

I have two objects, QuoteInput and Insured. QuoteInput has one Insured and Insured belongs to QuoteInput. I don''t understand what I''m seeing. I assign an Insured to a QuoteInput. The Insured object has invalid data. I call save! on the quote input. QuoteInput has no validations. I expect two things to happen - 1) an exception should be thrown, indicating that there was a

Hi Qi, No, we don’t have loop fusion. The loop fusion transformation itself is easy, but the profitability and legality checks are challenging. For legality, you would need to analyze the memory that you access and figure out that it is legal to fuse the loops. For profitability you would need to predict the effect on performance. You would need to predict register pressure and resource

Dear R users! Does someone know about any algorithms / packages in R, that perform classification / regression / decision trees using multivariate splits? I have done some research, but I found nothing. Packages "tree" and "rpart" seem only to be able to do CART with univariate splits. Thank you for your help! B?lint -- Cz?cz B?lint PhD hallgat?
