Dear all, model.frame behaves in a way I don't expect when both its formula and subset argument are passed through a function call. This works as expected: model.frame(~wool, warpbreaks, breaks < 15) #> wool #> 14 A #> 23 A #> 29 B #> 50 B fun1 <- function(y) model.frame(~wool, warpbreaks, y) fun1(with(warpbreaks, breaks < 15)) #> wool #> 14

Hello, Rlisters I have to compute p-values that are on the tail of the distribution, P-values < 10^-20. However, my current implementations enable one to estimate P-values up to 10^-12, or so. A typical example is found below, where t is my critical value. ########### example - code adapted from Rassoc ####################### rho01 = 0.5 rho105 = 0.5 rho005 = 0.5 t = 8 z = 2

Full_Name: Yi-Xiong Zhou Version: 1.5.1 OS: win2000pro Submission from: (NULL) (64.169.249.42) Update() can not find objects when it is used in a function, which is in turn being called by another function. Here is a R script to show the problem: ######## begin of the test script ########## fun1 <- function() { x <- matrix(rnorm(500), 20,25) y <- rnorm(20) oo <- lm(y~x)

Dear List, I'm building an R syntax highlighting file for GeSHi [*] for a website I am currently putting together. The syntax file needs a list of keywords to highlight. How can I generate a list of all the functions in a base R installation? Ideally the list would be formatted like this: "'fun1', 'fun2', 'fun3'" when printed to the screen so I can copy

Dear all, I've started working with R (vs 1041) a few weeks ago, and now I'm having problems with the amount of memory. I'm working on the windows-me, my computer has 128 Mb of memory. I'm using the R under the emacs (ESS-5.1.20) and it is started by the command: Rterm --min-vsize=10M --max-vsize=100M --min-nsize=500k --max-nsize=1M I've been had problems when executing a

Hello everybody, I don't understand what I'm doing wrong. But it isn't possible that each element of the if-condition is tested for each vector element? y <- c(1:20) > y [1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 > if (y == c(4,5,9,11,17)) { print("yes") } else { print("no")} [1] "no" warning: In if (y == c(4, 5, 9, 11,

Dear R users, i have this problem with matrices i want to check between two matrices if they are isomorphic i will give an example for what excactly i want   1 -1  1                                 -1  1   1 -1   1  -1                                1  -1  -1   1  1   -1                                1   1  -1 this two matrices are isomorphic beacause if i change the first 2 columns the matrices

Hi! While investigating into the PR1782 I spent some time analyzing BasicAliasAnalysis.cpp. While the mentioned problem should be fixed now (I hope), I have discovered some other possibilities for a bug to occur. In the case of checking for aliasing of two pointer values, where at least one of them is a GEP instruction with out-of-bound indices, BasicAliasAnalysis can return NoAlias, even if the

Hi, I am currently involved in the development of two R-packages, pkg1 and pkg2. They should not be dependent on each other, as most users will only be interested in one of them. Still, I want pkg2 to provide one extra S3 method for three functions (fun1-3) in pkg1 for objects of a class defined in pkg2 (class2), for those users who actually have both packages installed. I think this

Hi, I have already asked a similar question without response (https://stat.ethz.ch/pipermail/r-help/2009-June/200300.html) so I am here reformulating in the hope that someone is able to help. If something is unclear, please ask. I am working on the development of two packages, pkg1 and pkg2 (based on work in two different projects). pkg1 is quite generic, pkg2 tries to solve a particular

Hi, I have already asked a similar question twice without response on the r-help list https://stat.ethz.ch/pipermail/r-help/2009-June/200300.html but this list might be more appropriate. If there is a particular reason for the lacking answers (unclear, missing information, the solution is obvious to everyone except me, etc), I would like to know. The description below is generalized, but I

Dear list, I encounter an error when I try to use ddply to generate means as follows: fun3<-structure(list(sector = structure(list(gics_sector_name = c("Financials", "Financials", "Materials", "Materials")), .Names = "gics_sector_name", row.names = structure(c("UBSN VX Equity", "LLOY LN Equity", "AI FP Equity",

It's an optimization opportunity! When behavior is undefined, we're free to interpret it to be "whatever makes optimization easiest." If the two do actually happen to alias, well, it's the programmer's fault anyways, because they were doing something undefined! --Owen On Nov 13, 2007, at 4:13 PM, Wojciech Matyjewicz wrote: > Hi! > > While investigating

Dear list!   I would like to write a function to transform matrix, which is input argument of a written function. It is easy with new matrix (see below), but my idea is to transform input argument (matrix) of function without any additional matrixes. Here is an example: fun1 <- function(xy) { xy <- cbind(xy[,1], xy[,2], xy[,1] + xy[,2]) return(xy) }   df1 <- matrix(c(1,2,3,1,2,3), ncol =

Hello, We've had a high priority feature request from a number of our customers to provide per-function optimization in our Clang/LLVM compiler. I would be interested in working with the community to implement this. The idea is to allow the optimization level to be overridden for specific functions. The rest of this proposal is organized as follows: - Section 1. describes this new feature

Hey, Is there any function plotting several "implicit functions" (F(x,y)=0) on the same fig. Is there anyone who has an example code of how to do this? The contour3d function in the misc3d package only work with the functions with three dimensions. Thanks a lot. Many thanks for your help. KnifeBoot [[alternative HTML version deleted]]

Sadly, this will break a very common idiom. In GCC, we discovered it to be common enough that it broke a *bunch* of C code. In particular, you will break struct foo { int a; char name[0]; } bar = malloc(sizeof (struct foo) + strlen("thisismyname") + 1); strcpy(bar->name, "thisismyname"); It only started turning up when we started doing higher level loop opts and used
