Hello all, I'm new to R and trying to figure out how to perform calculations on a large dataset (300 000 datapoints). I have already made some code to do this but it is awfully slow. What I want to do is add a new column for each "rep_ " column where I have taken each value and divide it by the mean of all values where "PlateNo" is the same. My data is in the following

Hi! I'm trying to build LLVM under cygwin. I have the latest version of cygwin and CVS versions of llvm, llvm-test and llvm-gcc. make of tools only succeeded. make of frontend succeeded too but full make of llvm failed on crtend in llvm/runtime/GCCLibraries with the following message: llvm[0]: Compiling crtend.c for Debug build (bytecode) /bin/sh: -c: line 0: syntax error near unexpected

Dear R-List member, I have installed the new version of R on my PC (see system details below). I can start the RGui with http_proxy succesfully. However, I do encounter two problems: 1) After starting the Rgui the following error message is displayed (vertical dots represent omissions of output): R : Copyright 2003, The R Development Core Team Version 1.7.0 (2003-04-16) . . . .

Hello all, I recently installed rpy2 so that I could use R through Python. However, R was not recognized in the command line. So I decided to add it to the PATH variables. But it just doesnt work.... And what I mean by it doesnt work is : No matter what I type at the prompt in DOS- be it R, Rcmd, R CMD, Rscript- it is not recognized as a command. Path variables used : 1. %R_HOME% -->

We have setup Samba 4.1 as a PDC. We have successfully connected several Windows 2008 Servers to the domain and created various users/groups. During an application installation on the Windows server, it runs the command in SQL server: master..xp_logininfo 'MYDOMAIN\useraccount' SQLserver is running as a service user created on the domain (here called MYDOMAIN) This returns: Msg

I recently ran into the following problem: when running ''rake clone_structure_to_test'', the task would spit out the following error twice: This program requires Microsoft SQLDMO 7.0 or later After many attempts to download this library, I reinstalled the SQL Server Client Tools. Still nothing. I tracked down the program that rake was having problems with: scptxfr.exe.

If you're building llvm-gcc4, you don't need the runtime libraries, so I'd just stick with the "tools-only" build and declare success. If you're building llvm-gcc3, I'd suggest you switch to llvm-gcc4 :) However, the problem appears to be your PATH variable. In your path you have the following directory: C:/Program Files/Microsoft DirectX SDK (June

Dear list, I have a vector (array, table row, whatever is best) of frequency values for categories (or bins), and I need to find the median category. Trivial to do by hand, but I was wondering if there is a means to do it in R in an elegant way. The obvious medioan(vector) returns the median frequency for the binns, and that is not what I want. i.e,: freq cat1 1 cat2 10

I'm using the dovecot available on Ubuntu Feisty (1.0rc17) and am trying to migrate from courier-imap. A really important feature for me from courier is that expunged messages end up in Trash where they are removed after 7 days. I can get an approximation of this feature as described in the documentation: namespace private { prefix = INBOX. seperator = . inbox = yes } namespace

The future is obvious (hot data tracking, using most appropriate device for the data, data migration). In my specific case I have a 250GB SSD and a 500GB HDD, and about 250GB of

Hi there! I've downloaded the MinGW shell, installed it as descripted in intall.txt, and also the gcc-core-3.4.2-20040916-1 and installed it.

Hi guys, I''m facing an error trying to run my app as mongrel_service, hope those who have faced similar issue can help to shed some lights. The app was fine when running from console, but when running it as a service, it failed when I try to upload ''image file'', it has no issue uploading other types of files. Environment: ------------ mongrel (1.0.1, 0.3.13.3)

When using Cygwin Rsync 2.5.6/OpenSSH 3.6.1 for copying files from Win2k->Win2k, I get 2 or 3 hung processes on the receiving-side out of about every 50 runs. These hung processes cause the system to be unable to reboot(?!), requiring a hard reset. Killing the processes allows a graceful reboot every time. I'm currently running both ssh and rsync as services on the recieving side.

Hi, If i set strict allocate = yes in samba to speed up the transfer of a mssql database dump, then btrfs does not compress the file. I have tried it also by just copying a small file in Windows to the samba share and the same. I have tried btrfs mount options autodefrag and then btrfs fi defrag -c and the file still does not get compressed. I have tried kernels 3.6.11, 3.8 and 3.10.7 on FC16

I would like to change where R stores the temporary files to my external hard drive in my iMac. This is important because the temporary files R creates are huge and I do not have enough available space in my internal HD. Again, this is for macOS. This change has to be temporary. Later I need to use the usual location for temp files in the internal HD. Thanks in advance, Kumar Mainali --
