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

Dear all-- I have been trying to get the tkrplot package to work in order to use the bioconductor package genArise. I am trying to build it on a Mac running OS 10.4.1 with R 2.1.1. Following a stanadard install from R here the error I get when I try to load tkrplot > library(tkrplot) Loading required package: tcltk Loading Tcl/Tk interface ... done Error in

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

Dear all, I am currently analyzing a set of arrays hybe on the lattest affy Drosophila 2.0 GeneChip. I am trying to run simple annaffy analysis but can¹t find what is the name of the annotation file I need to use. Here is the output of the AffyBatch object I am using: > expData AffyBatch object size of arrays=732x732 features (16749 kb) cdf=Drosophila_2 (18952 affyids) number of samples=4

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

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

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

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 Helpers, I am running R 2.6.2 on a Windows XP machine. I am trying to use regexpr to locate full stops in strings, but, without success. Here an example:- f="a,b.c at d:" #define an arbitrary test string regexpr(',',f) #find the occurrences of ',' in f - should be one at location 2 # and this is what regexpr finds #[1] 2

R-help, Sorry if this is more of a regex question than an R question. However, help would be appreciated on my use of the regexpr function. In the first example below, I ask for all characters (a-z) in 'abc123'; regexpr returns a 3-character match beginning at the first character. > regexpr("[[:alpha:]]*", "abc123") [1] 1 attr(,"match.length") [1] 3

Given a text like I want to be able to extract a matched regular expression from a piece of text. this apparently works, but is pretty ugly # some html test<-"</tr><tr><th>88958</th><th>Abcdsef</th><th>67.8S</th><th>68.9\nW</th><th>26m</th>" # a pattern to extract 5 digits > pattern<-"[0-9]{5}" #

Hi, I 'd like to match each member of a list to a target string, e.g. ------------------------------ mylist=c("MN","NY","FL") g=regexpr(mylist[1], "Those from MN:") if (g>0) { "On list" } ------------------------------ My question is: How to add an end-of-string symbol '$' to the to-match string? so that 'M' won't

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 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,

Hi, I'm trying to parse lines of the form: dan001.hin (0): fingerprint={256, 411, 426, 947, 973, 976} What I need is the sequence of number between {}. I'm using grep as match <- grep("{([0-9,\s]*)}",s,perl=T,value=T) where s is a character vector. But all I get is the whole string s. I tried using regexpr in an attempt to get just the sequence I wanted: match <-

Help-Rs,   I'm doing some string manipulation in a file where I converted a string date in mm/dd/yyyy format and returned the date yyyy.   I've used regexpr (hat tip to Gabor G for a very nice earlier post on this function) in steps (I've un-nested the code and provided it and an example of what I did below.  My question is: is there a more efficient way to do this.  Specifically is

Greetings R list, I am stuck on a simple syntax problem. I want to list all files in a directory, excluding files of a certain type. I have tried pattern matching as follows: a <- list.files(data, full.name = TRUE, pattern != ".xml") # exclude all .xml files The warning returns that my syntax is incorrect. I have read the regexpr help files and search old posts to no

Dear all I encountered strange problem with regexpr replacement I made this character object str <- "02.06.10 12:40 " > str(str) chr "02.06.10 12:40 " I read in an object which seems to be quite similar > str(as.character(becva$V1)[1]) chr "02.06.10 12:40 " However I can not remove trailing spaces from it > sub(' +$',
