I stumbled across one of those intermittent bugs where the code sometimes works and sometimes doesn't. Below is an example run showing a failure where a CHARSXP object was not properly created (by the sub function?). I was able to reproduce this error on three different R builds in fresh R sessions, but it sometimes takes a few start up R -> run code -> close R iterations for the

Alguien sabe donde puedo encontrar algun datasheet gigante, de más de 5 gigas, para poder practicar con grandes volumenes de información? Lo que quiero es probar a cargarlos con h20 y crear modelos con ellos. Me gustaria sobretodo problemas de clasificación... Gracias Jesús [[alternative HTML version deleted]]

I have been retooling an S4 class definition to include another slot and have found that the methods::validObject function (defined in methods/R/SClasses.R) in R-devel throws an error that isn't caught internally (and thus not controllable by 'test' argument) when retrieving a non-existent slot. The offending line of code is shown below: > validObject function (object, test =

I've stumbled across an issue with aggregate.ts that either is due to a misuse of %/% or something deeper relating to numerical precision on Windows. The test code is x <- rep(6:10, 1:5) as.vector(aggregate(as.ts(x), FUN = mean, ndeltat = 5)) On Linux and Mac I get the correct answer > x <- rep(6:10, 1:5) > as.vector(aggregate(as.ts(x), FUN = mean, ndeltat = 5) [1] 7.2 8.8

Hi, I am getting unexpected behaviour from aggregate.ts(). The 'ndeltat' argument is effectively being reduced by 1 in some cases, even when it is an integer, with the result that the blocks to be aggregated are not of the expected size, and also that the end() of the aggregated series is much later than the end() of the original series. rawts <- ts(rep(1:10, each = 5), start = 1) ##

Hello, Suppose in the following code, PROTECT(sr = R_tryEval( .... )) sr is a RAWSXP vector. I wish to return another RAWSXP starting at position 13 onwards (base=0). I could create another RAWSXP of the correct length and then memcpy the required bytes and length to this new one. However is there a more efficient method? Regards Saptarshi Guha

Hi All, I've been having a little trouble with creating a loop that will run a a series of t.tests for inspection, Below is the code i've tried, and some checks i've looked at. I've used the get(paste()) idea as i was told previously that the use of the eval should try and be avoided. I've run a single syntax to check that my systax is correct and works without any problems

This issue ties loosely into other recent S4 topics on this board. The methods package defines a number of implicit generics for linear algebra related functions (rcond, norm, backsolve) that, when used, interfere with base package operations. Here is the cut-and-paste version of the code the illustrates the problem: # rcond x1 <- cbind(1, 1:10) rcond(x1) setGeneric("rcond")

...e hit a snag because the BioC build system has long path names (e.g. D:\biocbld\bbs-2.2-bioc\R) and these path names are not resolving properly by MiKTeX 2.7 during vignette construction.
