similar to: finding values for arguments?

Hi, Let's say I have a data frame (called "example") with numeric values stored (columns V1 and V2). I also have a string variable storing this name x1<-"example" Is there a way to use the variable x so that R knows that I want the specified action to occur on the data frame? For example, summary (x) would return a summary of the data frame? I am considering this

Hi, I've searched online, in a few books, and in the archives, but haven't seen this. I believe that xerror is scaled to rel error on the first split. After fitting an rpart object, is it possible with a little math to determine the percentage of true classifications represented by a xerror value? -seth -- View this message in context:

Hi, I have probability estimates from two predictive models. I have these estimates and also a binary outcome for a validation data set not used in calibrating either model. I would like to calculate the Brier score for both models on this binary outcome and test the hypothesis that the Brier scores are equal from the two models. I have not been able to find an R function to do this, can

Hi, I am reading a large space-delimited text file into R (41 columns and many rows) and need to do run each row's values through another R object and then write to another text file. So, far using readLines and writeLines seems to be the best bet. I've gotten the data exchange working except each row is read in as one 'chunk', meaning the row has all values between two quotes

Hi, I would like to specify a spherical correlation structure for spatially autocorrelated residuals in a model based upon the logistic function of a response that is a proportion (0 to 1) (so usual binary logistic regression is not an option). There is no need for a g-side random effect with grouping in this model. Am I correct that nlme requires this (meaning a correlated error structure only

I just discovered what seems to me to be a slight funny in respect of formal argument names. If I define a function foo <- function(a,b){ ... whatever ...} then ``inside'' foo() the exists() function will return TRUE from ``exists("a") whether an object named ``a'' exists or not. But get("a") will yield an error ``object "a" not found''

Hi all, One of the things I find most problematic in R is the partial matching of names in lists. Robert and I have discussed this and we believe that having a mechanism that does not do partial matching would be of significant benefit to R programmers. To that end, I have written a patch that modifies the behavior of "[[" as follows: 1. [[ gains an 'exact' argument with

I have installed samba 3.0.0 on a RedHat 9.0 box. I have used the rpm binary i got from Canada mirror. The server is a dual Pentium II 400 IBM NetFinity 5000. Installation was easy.

Actually doing both sounds good to me. Can you explain further about ringing them all at once? Here is how I tried to make mine work and failed... {global} PHONES0=SIP/2000 PHONES1=SIP/2001 [local] exten => 6001,1,Dial(${PHONES0&PHONES1),20,trf) When I dial 6001 I see my debugger tell me that I am using the wrong syntax. Do you know the correct syntax for ringing them all at once? I

Dear developers, has anyone experienced the problem described below? Is it a bug in handling interrupts in R?

Hi, after updating R 2.5.0 devel yesterday we today observed many new unexpected failures in our daily package build and test system runs, which can be traced to recent changes in the implementation in try() (as noted in NEWS). Investigating this new implementation I come across an issue in conjuntion with using S4 classes and methods. try(expr) does not return an object with attribute

Hi all, The write_PACKAGES function has a 'fields' argument that allows a user generating a PACKAGES file to specify additional fields to include. For symmetry, it would be nice for the available.packages function to be able to read those extra fields when specified. Similarly, it would be useful for installed.packages to have a 'fields' argument. This would allow a user to

I keep getting repeated copies of ``R-help post acknowledgements'' in respect of a couple of postings that I made to the list this morning (my time). I only posted each posting *once*. I hope that others are not getting repeated copies of my postings .... I mean I *know* my postings are so wonderful they merit re-reading, but one does not need another copy in order to re-read! :-)

Seth, Thank you for your reply. I'm sorry to bother with this, but what is the "root pivot" function and where can I find doc's on it. From what I understand from your email the system would basically boot twice. Once from a stripped kernel on the floppy disk to mount the CD, and then after the CD is mounted it would reboot with the kernel and initial randisk found on the

That could be it. What I want to do is set a group of callers and have the event cause the phone to ring them in order. I will tie it to my IVR portion and thus I can make sure peole in sales get calls based on our hierarchy in the office. So if I am reading your example right the syntax is.... Exten => 501,1,Dial(SIP/PHONE1&SIP/PHONE2&SIP/PHONE3), rtf) Is that a valid way to cause

I was flummoxed for a long time by errors generated when I did something like install.packages(foo,lib="Rlib") where ``Rlib'' is my personalized directory of R packages, which lives in my home directory (from which I started R before issuing the foregoing install.packages() call. Recently someone (I forget who, but thanks very much to whomever it was) pointed out that I

kernel 2.6.32-279.9.1.el6.x86_64 does not build from the source rpm's using the UNmodified config file and following the directions explicitly. Previous kernels build fine from the same directions. A little help from the developers would be greatly appreciated. while building I get this output: c1: warnings being treated as errors drivers/base/platform.c:621: error:

I've been experimenting with install.packages and it's new ability to track down dependencies from a list of repositories and encountered this: install.packages(c("foo", "bar"), repos="http://cran.r-project.org", dependencies=c("Depends", "Suggests")) dependencies 'foo' are not availabledependencies 'bar'

I have a moderately complex graph with three panels. There are data points plotted, and fitted lines are added using a panel function, which includes "with(alt.data[[which.packet()[1]]]" statements. It all graphs out beautifully, but none of the usual tricks to get the proper legend to plot are working, i.e., using auto.key, key, etc. One message I keep getting is Error in
