Hi, Does anyone know where the following package is available: Holleczek B, Gondos A, Brenner H. PeriodR - an R package to calculate long term survival estimates using period analysis. Methods of Information in Medicine 2009; 48: 123-128. Thanks Jens Oehlschl?gel -- GRATIS f?r alle GMX-Mitglieder: Die maxdome Movie-FLAT!

Hi, Is there any official way to determine the colClasses of a data.frame? Why has POSIXct such a strange class structure? Why is colClasses "ordered" not allowed (and doesn't work)? Background ========== I am writing a chunked csv reader that provides the functionality of read.table for large files (in the next version of package ff). In chunked reading, one wants to learn the

I am going to document a 10.000 lines of R code project. Before reinventing the wheel, has anyone written a function that analyzes dependencies between R functions? I am thinking of output like caller1 calee1 caller1 calee2 caller1 : caller2 calee7 : and I would like to restrict caller and callee to certain positions in the search path. My guess is, that a quick and dirty solution is

Dear all, differing from the standard behaviour of 'format' the current (2.7.0) 'format.factor' destroys attributes like 'dim' and 'dimnames'. This unfortunately breaks some general code in the new package 'ff' for large file-based data which will support vectors and arrays of atomic and factors. It would be nice if you could include the following fix in

Can please someone familiar with the R internals enlighten me on the following strange observation: # this is IDENTICAL as expected identical(substitute(substitute()), substitute(substitute())) # but NOT EQUAL !???? substitute(substitute()) == substitute(substitute()) # I originally found it on t2 <- function(e){ substitute(e) } t2(substitute(x==y, list(y=y)))[1] # I would expect all

Can please someone familiar with the R internals explain on the following: PR#1434 from r-bugs clarifies that assign("a[1]", x, SomeOtherFrame) or assign("a$a", x, SomeOtherFrame) will NOT assign to an object 'a' in the other frame BUT create a new object called 'a[1]' resp. 'a$a'. This leads to the following question: what is the most

Some days ago a problem with perl under WinNT was reported, which lead to > > t1 <- read.fwf("d:/maj/consulting/MarkStevens/matrix.txt", width=c(4, 22, > rep(7, 8))) > Error: "scan" can't open file I installed perl from the WindowsNt Recource Kit CD (Sept. 98) and encountered the same problem: Scan couldn't open the file - because perl did not produce

I just tried to batch-start rgui.exe (not rterm.exe) in a way, that it read.table()s data from a file with changing filename. As I understand no command line parameters are available for that, so instead I tried to pass the filename to an approbriate .RProfile, which works roughly, BUT ## this is my %R_USER%\.RProfile im <- read.table("d:/temp/im/temp.csv", header=TRUE,

Hello syslinux mailing list users, I've initially filed a bug about my problem [1], but people from irc channel suggested to ask for help here. I have a PXE server based on syslinux 4.05 that distributes ReactOS to client machines over network. It has a pretty simple pxelinux.cfg/default, with the following contents (that were suggested by ReactOS wiki [2]): DEFAULT chain.c32 APPEND

Dear all, is there any function to calculate the center of a polygon mass in R? Actually I need to find the best location within polygons to place labels. Thanks for any hint Jens Oehlschl?gel -- COMPUTERBILD 15/03: Premium-e-mail-Dienste im Test\ --------...{{dropped}}

Thanks for the quick response Ivan. readLines with encoding='latin1' works for me (on Ubuntu). However I was more concerned with the inconsistency in results between substr and regexpr. I was expecting that if one of them errors because of an unknown encoding then the other should as well. Even better, if regexpr works, why shouldn't substr work as well? Incidentally the analogous

R allows you to dynamically extend a vector by assigning past the end. So if a has length 10, then assigning to a[11] creates also a[11] with value a2[11] NA. So a is now length 11, while a2 is still length 10. So the occurrence of a[11] has a different meaning on the assigned-to side than on the assigned-from side. E.g. >a <- rep(1,10) >b <- 11 >a2 <- a >a[b] <- a2[b]

Hi, Im posting here the next doubt: Yesterday a korean company has released a new OS which is compatible with MS Windows Apps. As they state, they are a propietary OS, and i cant see any GPL code or SVN repository.Of course my lack of Korean can help to not find the open source code,but the little im able to read seems they arent going to release any source code. I know that is quite difficult

Hi all, I'm getting the following error from substring: > substr("<I>Jens Oehlschl\xe4gel-Akiyoshi", 1, 100) Error in substr("<I>Jens Oehlschl\xe4gel-Akiyoshi", 1, 100) : invalid multibyte string at '<e4>gel-A<6b>iyoshi' Is that normal / intended? I've tried setting the Encoding/locale to Latin-1/UTF-8 but that does not help. nchar

Full_Name: Jens Oehlschl?gel Version: 2.10.0 OS: Windows XP Professional Submission from: (NULL) (85.181.158.112) file.rename() will successfully rename file a to b - even if b exists already. Though the documentation does not state what file.rename() will do in this case, I guess the expected behaviour is to fail and return FALSE. Kind regards Jens Oehlschl?gel > cat("a\n",

Hi, When trying to generate very long strings, my R hangs without any error message, even if given much memory. # e.g. x <- character(10) for (i in 1:10) x[i] <- paste(1:1000, collapse="abc") paste(x, collapse="") # or directly paste(1:10000, collapse="abc") Am I violating any max(nchar(character())) or is this a bug?
