Hi all, I have noticed incorrect parsing of very small hexadecimal numbers like "0x1.00000000d0000p-987". Such a hexadecimal representation can can be produced by sprintf() using the %a flag. The return value is incorrectly reported as 0 when coercing these numbers to double using as.double()/as.numeric(), as illustrated in the three examples below:

I have a large Sweave report that reads data from a database file. Some of the columns are 1-character strings containing only +, - or NA. An example for such a table is shown below, and can be downloaded for easier testing from http://www.menne-biomed.de/uni/test.zip (For security reasons, the file is zipped) table test hp hp1 + a - + library(RODBC) channel =

Dear list-subscriber, in the process of writing a general code snippet to extract coefficients in an expression (in the example below: 0.5 and -0.7), I stumbled over the following peculiar (at least peculiar to me:-) ) sorting behaviour of the function all.names(): > expr1 <- expression(x3 = 0.5 * x1 - 0.7 * x2) > all.names(expr1) [1] "-" "*" "x1"

Hello, eveRybody, I've been trying to find the origin for the following formatting-"inconsistency": E. g., look at the number of digits in summary.defaults()'s output when NAs occur: in my example below the number of NA's is displayed as an integer, the rest as numeric (floating point numbers): > summary.default( c( 1:2, NA)) Min. 1st Qu. Median Mean 3rd Qu.

>From the language guide: "The one non-intuitive notation for constants is the optional hexadecimal form of floating point constants. For example, the form 'double 0x432ff973cafa8000' is equivalent to (but harder to read than) 'double 4.5e+15'. The only time hexadecimal floating point constants are required (and the only time that they are generated by the disassembler) is

Hello R, To analyze multi-level data, I started learning and using lmer. So far so wonderful. I then found some useful functions in package languageR. But then the following problem ocurred: Whenever I load and use the languageR package, then save the workspace - or quit R with saving the workspace - I am unable to reload that workspace in a later session. That is, R doesn't start at all

I am trying to run inline/Rcpp under Windows 64. The RTools are installed on a spaceless path D:\rtools. Inlining pure c-code works perfectly. When I try the sample code for cpp in the cxx Documentation, I get: x86_64-w64-mingw32-g++.exe: C:/Program: No such file or directory The path to the compiler is correct. Obviously there is some problem with the space in C:/Program (Files). Any ideas

Dear R-Devel subscriber, as a follow up to my yesterday's email: I tested an analogous example with the S4-package "flexclust" by executing the following code: library(flexclust) example(cclust) cl After saving the work space and starting a new R process with the restored work space, the same behaviour (i.e., the methods pertinent to "flexclust" are not used, even after

Dear guRus, I am trying to replace "~" by "$\sim$" for TeX. However, I can't get the backslash to work. I would like to turn "DV~IV" into "DV$\sim$IV". sub("~","$\sim$","DV~IV") => "DV$sim$IV" sub("~","$\\sim$","DV~IV") => "DV$sim$IV"

Dear developers, I have come across a (somewhat strange) change in the encoding of Sweave output from R-2.9.2pat to R-2.10.0beta (apparently specific to Rgui) on Windows installations. Of course, the NEWS file contains quite a few changes concerning encoding, but I was not able to locate an entry which explains the observed behaviour. I am not very familiar with encodings/locales/codepages,

Dear list, I have a balance connected to the serial port of a windows machine ("COM1") and I read the text output of the balance with scan("COM1", what="character", sep="\n", n=1) after calling the previous line I press the print key on the balance which triggers sending one line of text to the serial connection and with R 2.9.2 I get something like Read

Sorry, to bother the list one more time: but the following worked at least for 'urca': in NAMESPACE I now included explicitly: import(methods) a fix of the 'urca'-package will be uploaded to CRAN on the weekend.

It appears to me based on my experiments with llvm-as that literal floating-point constants may be specified in the 64-bit IEEE hexadecimal format, but not in the 32-bit format. For instance, this file: target datalayout = "e-p:32:32:32-i1:8:8-i8:8:8-i16:16:16-i32:32:32- i64:32:64-f32:32:32-f64:32:64-v64:64:64-v128:128:128-a0:0:64- f80:128:128" target triple =

Dear list-member, I am currently developing a package with S4 classes. The NAMESPACE and DESCRIPTION is printed below. Within this package I have set a method "residuals" for two classes. In version 2.8.1 these two are reported whereas in R-Devel (2009-01-28 r47766). What have I missed? What has changed and how can I rectify the issue? Your help and pointers are welcome. For 2.8.1:

Dear guRus, I would like to loop over a medium amount of Sweave code, including both R and LaTeX chunks. Is there any way to do so? As an illustration, can I create a .tex file like this using a loop within a .Rnw file, where the "1,2,3" comes from some iteration variable in R? ################################################ \documentclass{article} \usepackage{Sweave} \begin{document}
