I am pretty sure that I came across a function that creates a vector of levels from a list but I just can't remember. Basically, I have something like > t <- list(A=c(4,1,4),B=c(3,7,9,2)) > t $A [1] 4 1 4 $B [1] 3 7 9 2 And I would like to get something like the following: t levels 4 1 1 1 4 1 3 2 7 2 9 2 2 2 I tried unlist without success. I also do remember that there is a

Dear R gurus, On the CRAN website, it says that a 64bit version for Mac OS Tiger would be release shortly. Do we know what are the expected dates? Will the packages be also compiled for 64bit? We are running large microarray analysis and we keep hitting the 3Gb memory limit. I saw that there is a version available on the development mirrors, but I am not too excited to replace our very stable

Dear all, I am processing a very long and complicated list using lapply through a custom function and I would like to generate some sort of progress report. For instance, print a dot on the screen every time 1000 item have been process. Or even better, reporting the percent of the list that have been process every 10%. However, I can't seem to figure out a way to achieve that. For instance,

Dear R gurus, I have a very embarrassingly parallelizable job that I am trying to speed up with snow on our local cluster. Basically, I am doing ~50,000 t.test for a series of micro-array experiments, one gene at a time. Thus, I can easily spread the load across multiple processors and nodes. So, I have a master list object that tells me what rows to pick up for each genes to do the t.test from

Since I'm a SAS programmer, I'm used to creating command files in an editor for submission later. Is there a way to do this in R? I'd need to retain an ouput listing and a log to check for errors. _________________________________________________________________ Send e-mail faster without improving your typing skills. d_122008 [[alternative HTML version deleted]]

Dear all, I have a dataframe with multiple observations and the levels as the last column, as in: d <- data.frame(A=sample(1:100,12),B=sample(1:100,12),levels=c(rep('A',4),rep('B',4),rep('C',4))) > d A B levels 1 77 40 A 2 14 18 A 3 56 7 A 4 46 27 A 5 63 35 B 6 80 21 B 7 3 54 B 8 93 76 B 9 5 46 C 10 16 53

Many thanks for the answers on my previous question, it got me started. Indeed, stack() was the function I was vaguely remembering. However, I didn?t get very far because my data set is way more complicated then I expected. In fact I have a mixture of levels and lists within a list. Basically, it resemble the following list (named data) made of the levels H and the list of lists A and T. for each

A small how-to for encapsulating option 210 inside option 43 on Windows DHCP servers would be welcome then :-) And as far as UEFI x86 system go, one would simply have to create another vendor class with the value PXEClient:Arch:00006 On Wed, Jan 15, 2014 at 12:05 AM, Gene Cumm <gene.cumm at gmail.com> wrote: > On Tue, Jan 14, 2014 at 8:52 PM, Alexandre Blanchette > <blanalex at

Dear all, I am still fairly new to R and try to analyze large tables of data generated from genomic experiment. Currently, I am trying to plot pair of experiments coming from different file, trying to look at the behavior of individual feature in pair of experiment. My problem is that I have independent list from different source and I would like to plot the pair of value using a common key. As

I am fairly new to R and I am writing a script that would take a file, as an input, and generates a bunch of graphs out of it. My first task is to be sure that the file is of the right type by looking if there is a valid barcode in it as in (the barcode is beetween a double and single underscore): library(tkWidgets) ############## #Loading a file #testing if valid if not kill the execution

We are doing a deployment across many sites, we're doing one site at a time and we're bringing a "mobile server" (a laptop, really) to keep traffic local instead saturating the WAN link of each site. I'd like to make a script so each client can determine if the mobile server is on the same subnet either with a ping with a zero TTL value, with the ip/netmask and a bit of

In PXELinux 4.06 (the vanilla version, not gpxelinux.0), I'm trying to use pxechn.c32 to call iPXE (undionly) with option 67 set to call an iPXE script. The relevant portion of my PXELinux config looks like this: LABEL MDT MENU LABEL ^B - MDT 2012 SP1 com32 pxechn.c32 APPEND undionly.kpxe -o 67.s=ipxe/mdt.ipxe However iPXE doesn't seem to get the option correctly, it goes into

Dear all-- I am still forging my first arms with R and I am fighting with regexpr() as well as portability between unix and windoz. I need to extract barcodes from filenames (which are located between a double and single underscore) as well as the directory where the filename is residing. Here is the solution I came to: aFileName <-

I'm currently using Microsoft DHCP to enable PXE booting. I've set options 66 and 67 for the relevant scopes and it's all fine and dandy. However, UEFI machines won't initiate PXE boot, they don't seem to recognize the options. Is there another setting that need to be set? And how to I filter UEFI clients so I set option 67 to the right value (lpxelinux.efi)? -- Alexandre

I've found a way to support PXE booting both UEFI and BIOS architectures with Windows Server DHCP. This method uses a feature introduced in WinServer 2012: DHCP policies. First, in the the DHCP console, at the IPv4 root of the server, create a vendor class named PXEClient (UEFI x64) with the following value: PXEClient:Arch:00007 Then create your configuration for your BIOS clients in your

Is there a way to show some bits of information in the menu, like Syslinux version, MAC address and IP address? When the menu is loaded at startup, this information is quickly erased and is not easily readable. -- Alexandre Blanchette <blanalex at gmail.com>
