Dear all, I have quite large code (with lapply and mclapply) and I am getting the following error. Error: serialization is too large to store in a raw vector Is it possible to ask from R to extend the Error messages with more details? I would like to see where this problem exists.

Loading an S4 object from a file without first loading the library sometimes (?, the example below and actual example involves a virtual base class and the show generic) leads to incorrect dispatch (to the base class method). The attached package reproduces the problem. It has setClass("A") setClass("B", contains="A") setMethod("show", "A",

Hi Martin, Indeed it does (and I should have confirmed myself with R-patched and R-devel before posting...) Thanks, and sorry for the noise.

as.factor / as.ordered is not written as a generic. This differs from as.numeric, as.matrix, and other as.*. The following seems to address this and does not break make check-all. FWIW, the patch is against r55563, because with r55564 I see /home/mtmorgan/src/R-devel/src/main/dounzip.c:75:15: error: storage size of ?dt? isn?t known /home/mtmorgan/src/R-devel/src/main/dounzip.c:88:5: warning:

Hi Martin, It is really a 'PATH' problem. After adding C:\Program Files\Graphviz2.20\bin to the 'PATH' environment variable, the Rgraphviz package can be loaded without any error messages. Sorry that I ONLY set my 'PATH' environment variable correctly for R but not for Graphviz. Thank you and Duncan so much for your great help. Howard On Tue Mar 30 18:12:54

To test two environments for object equality (Lisp EQ), I can use 'identity': > e1 <- environment(local(function()x)) > e2 <- environment(local(function()x)) > identical(e1,e2) # compares object identity [1] FALSE > identical(as.list(e1),as.list(e2)) # compares values as name->value mapping [1] TRUE # (is there a

After upgrading my servers to 2.14, log files were filled warnings that 'mem.limits' has been deprecated and to use gc instead. After reading the NEWS for R 2.14.0 and PR#14795 I learned that it is actually deprecated without replacement. Hereby I just want to voice that this function was actually in use by at least several users. Among other things, it is a useful to limit per-session

Hi, I was wondering if anyone has played around this this package called "rdict"? It attempts to implement a hash table in R using skip lists. Just came across it while trying to look for simpler text manipulation methods: http://userprimary.net/posts/2010/05/29/rdict-skip-list-hash-table-for-R/ Cheers, Paul [[alternative HTML version deleted]]

Dear list I am running some simulations in R involving reading in several hundred datasets, performing some statistics and outputting those statistics to file. I have noticed that it seems that the time it takes to process of a dataset (or, say, a set of 100 datasets) seems to take longer as the simulation progresses. Has anyone else noticed this? I am curious to know if this has to do with how R

Hi, from the man page ?methods, I expected to be able to build pairs (class,package) for a given S3 method, e.g., print, using attr(methods(print), 'info'). However all the methods, except the ones defined in base or S4 methods, get the 'from' value "registered S3method for print", instead of the actual package name (see below for the first rows). Is this normal

I have postfix/dovecot/mysql installed using MacPorts on a quad-core 2.8GHz MacPro running Snow Leopard (10.6.2). I moved the base mail directory to a pair of 10k RPM Raptors that are mirrored (/Volumes/email/) and everything seems to be working fine on an unused domain with very little traffic. I used imapsync to pull everything from the current mailserver to this test server to play with. Our

Hello, I'm using R-2.9 and have a question about integer ranges. On C, (OS X platform), LONG_MIN and LONG_MAX(from limits.h) correspond to -2147483648(-2^31) and 2147483647 (2^31-1) In Java(1.4), Integer.MIN_VALUE and Integer.MAX_VALUE have the same values. On R, as.integer(2^31-1) is the maximum (without returning NA) but the lowest is -2147483647 (-2^31+1) > as.integer((-2)^31) [1] NA

Hi everybody! I'm creating an object of a S4 class that has two slots: ListExamples, which is a list, and idx, which is an integer (as the code below). Then, I read a data.frame file with 10000 (ten thousands) of lines and 10 columns, do some pre-processing and, basically, I store each line as an element of a list in the slot ListExamples of the S4 object. However, many operations after this
