Hello everybody, I found that queries (send by "dbExecStatement" ) with more than 4000 characters length produces an error in ROracle (ver 0.3-3). Maybe there is a limitation of 4kB.... Is this a bug? If yes, is this problem solved in the latest version of ROracle (ver 0.5-0)? My system information: platform sparc-sun-solaris2.8 arch sparc os solaris2.8

Hello everybody, is there a possibility to install and use multiple versions of a R library at the same time? A few words regarding the background of this question: If I change functions of an already developed package, I have to verify complex functions in a lot of R applications. So it would be useful to use different versions of a function/library and switch to the newer function/library

Dear R community, I tried to optimized my R code by using Rprof. In my R code I'm using MySQL database connections intensively. After a bunch of queries R fails with the following error message: Error in .Call("RS_MySQL_newConnection", drvId, con.params, groups, PACKAGE = .MySQLPkgName) : RS-DBI driver: (could not connect mylogin@mydatabase on dbname "myDB"

Hello everybody, if I try to (r)bind a number of large dataframes I run out of memory because R wastes memory and seems to "forget" to release memory. For example I have 10 files. Each file contains a large dataframe "ds" (3500 cols by 800 rows) which needs ~20 MB RAM if it is loaded as the only object. Now I try to bind all data frames to a large one and need more than

Hello everybody, could anybody give me a hint, who I can use rbind on a list of data.frames, please? I have a list with a large number of data.frames of the same structure, like: LIST <- list(X1=data.frame(a=1,b=2), X2=data.frame(a=3,b=4), X3=data.frame(a=5,b=6), ...., XN=data.frame(a=i,b=k)) I would like to bind all data.frames very fast to a single data.frame, something like that: DF <-

Hello everybody, could anybody give me a hint how to to use RMySQL and ROracle libraries at the same time without getting conflict with name spaces? Because it needs to much time, unloading and reloading the libraries is no solution... Example: ----------- snip ----------------- library(ROracle) library(RMySQL) mysql <- MySQL() con <- dbConnect(mysql, user=MySQL.name, password=MySQL.pwd,

Hello everybody, if I'm using par(xpd=NA) gridlines will plotted outside the plotting region. This is "new" (and, in my opinion, unaesthetic) in version 1.4 - compared to version 1.3. Is this a bug or a feature? Example: ------------------ par(xpd=NA) plot(1:11) grid() ------------------ platform sparc-sun-solaris2.6 arch sparc os solaris2.6

Hello everybody, if I'm running a R-script on a command line R-session which uses the function "try" and I'd like to interrupt the execution of my R-script pressing "CTRL-C" than R ignores the first "CTRL-C" key stroke and after I pressed "CTRL-C" second time R by itself is interrupted and I fall back to the (UNIX-) command prompt.

Hi, Attached patch tells the linker where to find libxenctrl.so.3.2, libxenguest.so.3.2 and libxenstore.so.3.0 when launching qemu-dm.

Hello everybody, I have following string type and try to convert it to float: > a<-"20020104.123456" > str(as.numeric(a)) num 20020104 > str(as.real(a)) num 20020104 > str(as.double(a)) num 20020104 How can I get an float instead of an integer? How can I set the desired precision? Thanks in advance Lutz Thieme Lutz Thieme AMD Saxony Manfacturing GmbH Product

Hi! Attached patch makes git-ioemu compile on NetBSD. Signed-off-by: Christoph Egger <Christoph.Egger@amd.com> P.S.: I''m about sending the pieces to qemu-devel.

Hi! On BSD, mmap()ing files works on on-disk files but not on pseudo filesystems like kernfs or procfs. Therefore, attached patch mmap()s anonymous memory. Linux equivalents are sysfs and procfs to above BSD''s pseudo-filesystems. On Linux, mmap is implemented for sysfs but it is questionable to me how write operations work since (most) files in sysfs have static content. So this patch

Hello everybody, is there a way to get the file name of the source file from which I read and execute my R code? In other words: If I'm executing "source('myRfile.r')" I'd like to have a statement inside myRfile.r like "src.file<-$0" (in unix csh style) which assigns th variable src.file to 'myRfile.r' . Thanks in advance! Best regards, Lutz

Keir, I noticed that a Shadow patch went into the 3.1.1 staging tree today. Does this mean that we should expect a 4th release candidate before the 3.1.1 release tag is official? If so - how much testing time are you going to give that release candidate before deciding whether a release tag, or another RC round is appropriate?

Hi! If there is a string table for section headers, it also gets loaded. Therefore take it into account in size calculation for kernel symtab. Also there is no need to call elf_set_verbose() a second time after elf_init() (First call happens within elf_init()).

Hi R-help community, Can anyone tell me why, while using : x <- seq(as.Date("2001-01-01"),as.Date("2001-01-01") + nrow(volcano)-1,1) y <- seq(1, ncol(volcano),1) when I plot the volcano matrix with that command : filled.contour(x,y,volcano) the graph has a Date format on X-axis, ok ... ... but when adding a contour plot to the filled contour, using this

Hi Keir, For HVM guests, all cpuid Fn''s going through domain_cpuid() iterate over the loop and then return 0 for all four registers. Guests OS''s and cpuid tools in HVM which query for cpuid Fn 0000.0000 %eax and 8000.0000 %eax, see the value 0 and think, Xen emulates oldish 386/486 CPUs. This leads to strange boot failures, "your CPU does not support long mode" or

Hi! Whenever I save a graphic in ps/eps format generated by filled.contour or image, an undesired grid is added to it (not visible on the X11 screen). For example: postscript("volcano.eps") filled.contour(volcano,col=gray(seq(0,1,,50)),levels=seq(min(volcano),max(volcano),,50)) dev.off() Any ideia how to eliminate this grid?
