Hi all, Is there any way to add notes or comments to R objects? It can be hard for me to come up with a descriptive name that encapsulates all the differences between data sets, so it would be very helpful if I could add a note which described the object. I didn't find anything like this in the R docs. Regards, Matt [[alternative HTML version deleted]]

Dear R People: Could someone recommend a good reference on regular expressions, please? Thanks in advance, Sincerely, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston - Downtown mailto: erinm.hodgess at gmail.com

Dear list! > gregexpr("a+(b+)", "abcdaabbc") [[1]] [1] 1 5 attr(,"match.length") [1] 2 4 What I want is the offsets of the matches for the group (b+), i.e. 2 and 7, not the offsets of the complete matches. Is there a way in R to get that? I know about gsubgn and strapply, but they only give me the strings matched by groups not their offsets. I could write

Hi Experts, This might be silly question that I am asking, but no way as I am new to R. I want to list the files in a directory using regular expression like A_B*_C*.csv etc. How to make this possible in R ? I tried like this list.files(dir=".", pattern="A_B*_C*.csv") but this gives no output, whereas list.files(.... pattern="*.csv") giving all the .csv files in

Dear R users: When I create a table without Major Column headings, my *regular* column headings appear correct in the typeset latex file. The major row heading and row groups are as they should. w <- latex(mytab,title="",file="tab/my.tex",ctable=TRUE,caption="Descriptive statistics by

I have a reshaped data frame with value column headings concatenated from two column headings in the melted data frame. I want to change all 56 headings in a single command, but 'names' allows me to change only one at a time. In Hadley's 2007 article on reshape in the Journal of Statistical Software he mentions a 'rename' function, but I cannot find that. Is there a way to

Dear R-users, The numerical integration example given in Gentleman and Ihaka (2000), "Lexical Scope and Statistical Computing," JCGS, 9, 491-508, is very interesting and helpful in understanding how lexical scope is about. However, I got some questions that I just can't figure out. First all, allow me to copy the two functions given by the authors: midpoint <- function(f, a,

I have tried everything to get BV working outbound. All worked fine until the BV change last week. I called BV and they changed me to sip gen with a new password. I stripped my Asterisk server to one phone on Zap/1 until I get this working. The same BV account works fine with a SPA-3000 so I don't suspect a firewall problem. Symptoms: Asterisk registers with BV Ok Incoming calls work

Let me start by stating that I've been thinking about setting up an unofficial broadvoice-users mailing list for a while. I've asked Broadvoice techs about it a couple times by phone and email and it looks like they haven't passed it up to the people who would make that decision or said people aren't interested in creating/maintaining one. If there's enough interest (read 10

I finally got my incoming and outgoing to work on Broadvoice with a configuration file that is no where close to the one given by them. Here it Is (sip.conf). For others who have a working config could u please share so that I could compare. Thank You [broadvoice] type=friend username=[number] fromuser=[number] secret=[password] host=sip.broadvoice.com fromdomain=sip.broadvoice.com

Hello All, I have one X100P card for inbound calls. I use two Broadvoice SIP accounts for all my outbound calls. I'm unable to place calls using BV. Inbound BV calls are ok. Verbosity is at least 3 -- Executing Macro("SIP/201-365c", "dialout-default|XXXXXXX") in new stack -- Executing GotoIf("SIP/201-365c", "1?4") in new stack -- Goto

Hello, I am currently attempting to introduce R at my company and am trying to import time series data from a text file into R to graph. The format of the text file is in date, data (e.g., 20040929 3.361). My problem is that I do not know how to get R to recognize the first column as a business date series. Or at the very least, I am unable to find a function that will grap the second column

Computer Friends, with the following example lines: [107] "98-610: Cell type: S; Surv(months): 6; STATUS(0=alive, 1=dead): 1" [108] "99-625: Cell type: S; Surv(months): 21; STATUS(0=alive, 1=dead): 1" i want to be able to isolate the number of months of survival for each row. is there a regular expression that can find the first instance of a ";", delete

I'd be grateful if someone could point me in the right direction. I have a Broadvoice trunk attached to Asterisk which I use for frequent calls to the UK using the following in extensions.conf exten => _0[1-68].,1,Ringing exten => _0[1-68].,2,Dial(SIP/BV/01144${EXTEN:1}) exten => _0[1-68].,3,Hangup The caller hears immediate ringing, though it seems that Broadvoice

I can call my Broadvoice DID from a outbound caller-id blocked phone, and BV happily delivers the CID to Asterisk (and then on to my IP phone display.) I've tested with the *67 prefix from a PSTN phone to make sure it was supposed to be blocked. The number is always correct, but sometimes the the caller ID name is set to something funky (like a CO or switch center name.) I *think* this

I'm using Asterisk 1.0.4 with AMP and Broad Voice. I have that with only 5 XTen Lite phones. I'm able to call / etc with internal phones just fine. I can call outside Vonage Numbers, and other BroadVoice Numbers. I have vonage where I live (626) and can call that fine. However, other 626 numbers I get similar errors as below. However, everytime, I try to call cell phones, and or

Hi all, I signed up for BV over the weekend. I have set everything up as per their howto. I can receive calls to my BV number but cannot make any. I'm running CVS head 1/30/2005 so assume that the patch is already in my code. Am I correct? Is it the patch that's stopping me from making calls? Mark

Hello all, I've tried to reproduce the contour plot that appears in the book of Venables and Ripley, at page 255. Is a F-statistic surface and a confidence region for the regression parameters of a non-linear model. It uses the stormer data that are in the MASS package. I haven't been able to reproduce the plot either in R ( version 1.5 ) and S. It makes the axes and it puts the
