Hi, We are currently using the odbcConnect and odbcDriverConnect functions of RODBC package to connect to a DB built on SQL Server 2005. Are there any other packages / drivers/ methodology that may provide a faster connection? Any help or advice would be appreciated. Thanks [[alternative HTML version deleted]]

Hi Everyone, as part of a larger script, I need to insert the result of a simple minus operation into an if statement. I have noticed that the precision that appear on the screen is not the precision in which R stores the result of the minus operation, and that this change alters the result of the if statement. For example, when running this simple script:   > a=0.90 > b=0.95 >

I am trying to get the Vim-R-Plugin<http://www.vim.org/scripts/script.php?script_id=2628> to work with gvim and R on Windows 7. When I open a .R file in VIM, it complains and says ""Python interface must be enabled to run Vim-R-Plugin." I have installed pywin32 for python 2.7, and added the following 4 lines to my _vimrc per the instructions

The main goal is to create an example to be used as template or guideline for contributors when they wish to create a new virtio device and to document "the right way" to do so. It consists of several parts: 1. The device specification * it can be found in the device header of the implementation * it will hopefully be added to the official virtio specification

Hi all, Where can I find an R binary version (>2.4.0 ) for windows that compiled with R_MEMORY_PROFILING? Within our application we are experiencing serious problems with memory usage. And being able to use "Rprofmem" and "tracemem" command seems like our best option. Thanks, Yoni [[alternative HTML version deleted]]

Hi, My query is regarding permutation test and reshuffling of genotype/phenotype data I have been using the haplo.stats package of R. for haplotype analysis and I would like to perform an analysis which I'm requesting your advice.

Hi All, There is something I don't quite understand about R memory management. I have the following function function (AdGroupId) { print(memory.size()) channel <- odbcConnect("RDsn", uid = "xxxx", case = "tolower", pwd = "xxxxxx") Tree1 <- sqlQuery(channel, "exec SelectAdgroups 111120,0", as.is = c(FALSE, FALSE,

I have a host running a few guests all configured to autostart. I'm also using libvirt-guests to suspend the guests when the host restarts or shuts down When the host comes back up I see a bunch of log messages - Resuming guest vm01 already active Resuming guest vm02 already active I guess this is because libvirt autostarts the guests when it starts and before libvirt-guests has a chance to

Hi all, according to the docs, the default precision for the Ferret Time to_s_lex function is :day. Should this not be :second? This is the same on DateTime. (Same on Date too, but that seems ok) http://ferret.davebalmain.com/api/classes/Time.html John. -- http://johnleach.co.uk

Hello all, I just recently opened supplied a patch for ticket #4498 (https:// rails.lighthouseapp.com/projects/8994/tickets/4498-rails-loses- precision-when-deserializing-timestamps-from-postgresql). In short, the current microsecond calculation converts a rational to a float, then to an integer, occasionally causing rounding error. I''ve supplied a patch against 2-3-stable (should also

Hi all, I have a problem in that when I plot points that have a high degree of precision, some significant rounding seems to occur, resulting in uneccessary overlap of my points. Is there a way to specify the resolution or precision in plotting functions? Is there an underlying grid I have to modify somehow? Many Thanks, Jon -- Mares eat oats and does eat oats and little lambs eat ivy. A

Hello, I was wondering if anyone knew if it is (or ever will be ) possible at all to specify things like precision and scale at generate scaffold time, and if so how. Things like price:numeric(8,2) (obviously) just break the script.

Hi, I am new to R, but have extensive experience in matlab. I have searched on the web and in Venabels & Ripley book but I was unable to find the equivalent of the eps function in matlab. eps returns the Floating point relative accuracy. thanks

Hello, is there a possibilty in R to convert numbers (double precision, 64bit) into single precision ones (32bit). I need that for compatibility reasons. Until now I call a C application which casts a double to a float. float precision32(double value) { return (float)value; } But I want to use a R only method. What can I do? Kind regards, Sebastian
