similar to: Handling 8GB .txt file in R?

Dear Experienced R Practitioners, I have 4GB .txt data called "dataset.txt" and have attempted to use *ff, bigmemory, filehash and sqldf *packages to import it, but have had no success. The readLines output of this data is: readLines("dataset.txt",n=20) [1] " "

Hi, I'm quite new to R (1 month full time use so far). I have to run loop regressions VERY often in my work, so I would appreciate some new methodology that I'm not considering. #--------------------------------------------------------------------------------------------- y<-matrix(rnorm(100),ncol=10,nrow=10) x<-matrix(rnorm(50),ncol=5,nrow=10) #Suppose I want to run the

Hello everyone, I need to create and work with some big matrices that actually have somewhat over 2 million columns and 117 rows. To do some calculations on such big matrices R just needs too much memory for my PC (4GB installed). So I need a solution to work with large datasets. I'm trying to use the ff-package but I don't think I really understand the whole functionality of the

Hello, The question is related to Droppables and Draggable. I''m creating a splitter component with a DIV that acts as the splitter and 2 DIV zones that are the splitted zone. To do so I use the Droppables and Draggable in conjunction. The splitter DIV is a Draggable component and I define 2 Droppable zones for the splitter DIV (Zone A and B on each side of the splitter) It works fine

wxRuby 0.3.0 has been released and is now available for download from RubyForge at: http://wxruby.rubyforge.org/ This release includes binary builds for Max OS X Panther and MS Windows. Hopefully, within a couple weeks I will release RubyGems for the source, and RubyGem binaries for Mac, Windows, and Linux. Please report any bugs or feature requests here:

Hi, I must say I'm very impressed with improvments in the latest versions of the encoder, especially in 2-pass mode. I was trying encodes of videos with sudden changes from no or moderate motion, to high motion scenes. Most samples of Theora quality I saw on the net were very slow motion usually. These high-motion videos were especially hard for Theora and it quickly introduced

Hi all, I have a question regarding connection of two Asterisk servers to our PBX. Each Asterisk server has one PCI E1 card, and they are in failover mode with Linux HA. On our PBX we have only one E1 card towards Asterisk servers. My question is how to connect these two Asterisks to one E1 card on PBX, and when primary Asterisk server fails not to have to manually pull out E1 cable from primary

Why is the width of an FXSplitter equal to 1 before the FXSplitter#create method is called? My splitter is configured to have LAYOUT_FILL_X, so wouldn''t its width be determined before its children were created? It''s not really a big deal, but I was configuring the split based on a preferences file during initialize, and couldn''t make it work properly. Doing it in

First of all, just wanted to say big thanks for all the great work on wxruby2 .. I''ve been a user of 0.6 for a long time and its proved very useful over the years. It''s great to finally have a multi-platform, gem installable ui toolkit that doesn''t suck! Secondly, thanks also for wx-sugar. I was drowning in sizers and started to write my own layout library ... but

Hi, I''ve written a small app implementing SplitterWindow and have a problem with specifying the sash position on Windows. At the moment, I call split_vertically and pass it a positive integer for position. This works as expected on FreeBSD and Linux (Ubuntu and Debian), but seems to have no effect on Windows. Is there something particular I need to be doing to get this to work on

Greetings, We present “Machine Function Splitter”, a codegen optimization pass which splits functions into hot and cold parts. This pass leverages the basic block sections feature recently introduced in LLVM from the Propeller project. The pass targets functions with profile coverage, identifies cold blocks and moves them to a separate section. The linker groups all cold blocks across functions

HI all, I'm new to R. Say I have a multi-layered list called newlist. ############ > str(newlist) List of 2 $ :List of 5 ..$ : num [1:8088] NA 464 482 535 557 ... ..$ : num [1:8088, 1:2] NA 464 482 535 557 ... ..$ : num [1:8088, 1:3] NA 464 482 535 557 ... ..$ : num [1:8088, 1:4] NA 464 482 535 557 ... ..$ : num [1:8088, 1:5] NA 464 482 535 557 ... $ :List of 3 ..$ : num

I have read what I could about SEL_UPDATE and I understand that the block(s) that get called "from" SEL_UPDATE only get called when "there is no more work to do". I took the splitter.rb example that comes with FXRuby. I put in a "puts" in one of the SEL_UPDATE blocks and I get about 4 a second. Not awful ... but ... why is it so slow? In my code which is ... more

Hi, I have a CentOS 7 desktop client installed on an old Dell Optiplex computer with an Intel video card integrated into the motherboard. The card has a single VGA connector, and the 19" monitor is connected to it. I wonder how I could connect a video projector to this computer while keeping the monitor, in a mirroring configuration, e. g. output is the same on the video projector and the

Hi, Are there any effort in making wxDocument, wxView, etc types of classes avaiable under wxRuby? For supporting SDI/MDI architecture. Cheers, Phuah Yee Keat
