hey, just did a yum install wireshark on a fresh and clean CentOS 4.6 box, and got a bazillion warnings about libsmi... # cat /etc/redhat-release CentOS release 4.6 (Final) # yum install wireshark Setting up Install Process Setting up repositories Reading repository metadata in from local files Excluding Packages from CentOS-4 - Updates Finished Excluding Packages from CentOS-4 - Base

I am trying to install the source code for samba. I have samba-3.0.28-1.el5_2.1 When I try and install the samba-3.0.28-1.el5_2.1.src.rpm. I get the following..... rpm -ihv samba-3.0.28-1.el5_2.1.src.rpm 1:samba warning: user mockbuild does not exist - using root warning: group mockbuild does not exist - using root warning: user mockbuild does not exist - using root warning:

Dear R-users, in a minimal example exists() gives FALSE on an object which obviously does exist. How can I check on that list object anyway else, please? > SmoothData <- list(exists=TRUE, span=0.001) > SmoothData $exists [1] TRUE $span [1] 0.001 > exists("SmoothData") TRUE > exists("SmoothData$span") FALSE > exists("SmoothData[[2]]") FALSE

Hi R-people, I have a question about lattice in general, and histogram specfically. How do you control the ordering of factors that controls the placement of the conditional panels. I have a dataset with factors that go 'Q1','Q2',"Q3','Q5' and of course I want the plot to place Question Q1 at the top and Question Q5 at the bottom of the graphical output.

Hi All, I've been looking into speeding up the loading of packages that use a lot of S4. After profiling I noticed the "exists" function accounts for a surprising fraction of the time. I have some thoughts about speeding up exists (below). More to the point of this post, Martin M?chler noted that 'exists' and 'get' are often used in conjunction. Both functions are

Thanks Winston! I'm amazed that "[[" beats calling the .Internal directly. I guess the difference between .Primitive vs. .Internal is pretty significant for things on this time scale. NULL meaning NULL and NULL meaning undefined would lead to the same path for much of my code. I'll be swapping out many exists and get calls later today. Thanks! I do still think it would be

Hi. I'm trying to use CentOS4.2 for some audio work (ie. sound editing, etc.). I found a site called PlanetCCRMA (http://ccrma.stanford.edu/planetccrma/software/) and decided that I would give some of their applications a try (hoping that it would not affect my system greatly!). At first I tried the Fedora 3 packages (and they do work), but what I really wanted to do is to download the

Some functions in R need quoted arguments. Consider this list: help(rm) rm(a) is.na(a) get("rm") exists("rm") Can someone explain why 'get' and 'exists' require quoted object names? Would it make sense (more consistency) to have these functions check to see if the first argument is a string, and if not, then 'substitute' it? Intuitively,

Configure gives me these errors on FreeBSD. I'm proceding with the build anyway to see what happens. Don't worry :) It'll only take about 2.5 hours instead of 30+ now. install: ../test/Programs/Makefile does not exist config.status: executing test/Programs/Makefile.programs commands install: ../test/Programs/Makefile.programs does not exist config.status: executing

Hi all, I'm trying to add updated data to an existing time series where an overlap exists. I need to give priority to the update data. My script runs every morning to collect data the updated data. There are quite often varied lengths, so once off solutions identifying rows to solve this example won't work. I've experimented with merge, rbind, merge.zoo, but to no avail. An example

Hi! Sorry for the newbie question... I''m following the depot example in AgileWebDevelopmentWithRails. Stangelly, generating scaffolding using the command (page 53): ./script/generate scaffold Product Admin does not generate any .rhtml file, but just: exists app/controllers/ exists app/helpers/ exists app/views/admin exists test/functional/

I've looked at related speed issues in the past, and have a couple related points to add. (I've put the info below at http://rpubs.com/wch/46428.) There?s a significant amount of overhead just from calling the R function get(). This is true even when you skip the pos argument and provide envir. For example, if you call get(), it takes much more time than .Internal(get()), which is what

In November, we had a "bug repository conversation" with Peter Hagerty and myself: https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16065 where the bug report title started with --->> "exists" is a bottleneck for dispatch and package loading, ... Peter proposed an extra simplified and henc faster version of exists(), and I commented > --- Comment #2

Hi. I'm having trouble testing for existence of an object inside a function. Suppose I have a function: f<-function(x){ ... } and I call it with argument y: f(y) I'd like to check inside the function whether argument y exists. Is this possible, or do I have to either check outside the function or pass the name of the argument as a separate argument? If I do exists(x) or

Today I tried two build R-devel_2011-02-06.tar.gz from sources on FreeBSD 9.0-CURRENT (amd64) with gcc-4.5.2 and I got the following messages when configuring: ./configure [..SNIP..] checking whether C99 double complex is supported... checking complex.h usability... yes checking complex.h presence... yes checking for complex.h... yes checking for double complex... yes checking whether cexp

After the removal of llvm/test/Programs and insertion of llvm-test cvs module, the nightly tester showed the following: x86 Linux debug: * hard to say. I think it failed because the check in occurred just as it was starting up. Could someone verify for me? No results were produced. x86 Linux optimized: * everything ran okay * loc graph now shows 550k lines (up 350k!) - not sure

All, So that suggests that .GlobalEnv[["X"]] is more efficient than get("X", pos=1L). What about .GlobalEnv[["X"]] <- value, compared to assign("X", value)?
