Dear R users: There appears to be a conflict between the statnet package and the igraph package. With igraph loaded into memory, the network() function of statnet failed, returning the error to the effect that the matrix being converted was "not a graph object." Removing igraph from memory restored statnet to proper function. Apologies if this is redundant. I could not find this

Dear R users, I would like to change the class of a group of objects in R memory from "numeric" to "dist". I can manipulate the class using class(foo) <- bar but I cannot get the same command to work on groups of variables. When I use for() loops and lists of names, inevitably I have to specify class(get("foo")) <- bar which causes class() to return an

Greetings, and many thanks for any insight you can offer. I have a network object on which I'd like to simulate an ergm() using {statnet}. Since the network object is large, I have not copied it here. Each vertex has an attribute "language" which can take on integer values greater than or equal to 1. Is there a way to use the nodematch argument of ergm(), such that it searches for

Hi all, I am running R version 2.4.0 (2006-10-03) on an i686 pc with Mandrake 10.2 Linux. I was given a binary data file containing single precision numbers that I would like to read into R. In a previous posting, someone suggested reading in such data as double(), which is what I've tried: > zz <- file(file, "rb") > h1 <- readBin(con = zz, what = double(), n = 1, size

We've been testing (aim:frziegler and aim:end1r) the Voicemail2 app for a few days now, based on a CVS build from Monday, 5/12/03-23:15. Works good! Thanks Mark! We seem to have found a bug in the MWI (Message Waiting Indicator) logic. By simply creating msg0000.txt files in both structures, e.g.: for extension 4000: voicemail1: /var/spool/asterisk/vm/4000/INBOX/msg0000.txt

Hi. Has anyone experienced hangup detection problems with the VoiceMail2 app? I have a console phone on the FXS port. When I call a SIP phone, and get its voicemail greeting, I can enter the VoiceMail2 app, leave a message, and then hit # to stop message recording. Recording does stop, but the channel stays up inside the VoiceMail2 app (as shown by a "show channels" command) for about

Many thanks to Martin Pycko and Mark Spencer. Mark's suggestion below was correct: "Maybe it's stuck trying to send the e-mail notification. If you take the e-mail address out of /etc/asterisk/voicemail.conf does that speed it up?" Indeed it did! The problem turned out to be a 60second delay while invoking mail, caused by a mis-configuration of my hostname and

Dear R Community: Recently, I have managed to plot some really useful graphs of my research data using persp(). I have even figured out how to overplot rectangular regions (corresponding to submatrices) with a different color. This is accomplished by using par(new=T). I am now searching for a way to "highlight" a set of (possibly non-contiguous) facets with a specific color,

Hello, I would like to use mapply to avoid using a loop but for some reason, I can't seem to get it to work. I've included copies of my code below. The first set of code uses a loop (and it works fine), and the second set of code attempts to use mapply but I get a "subscript out of bounds" error. Any guidance would be greatly appreciated. Xj, Yj, and Wj are also lists, and s2,

I got the error. I haven't been able to get a stand along case so that I can show it here. But could somebody give some clue on what could cause this error? Since I never defined xj[i], I don't understand where this error come from. Error in xj[i] : invalid subscript type 'list'

Below is a version of [.data.frame that is faster for subscripting rows of large data frames; it avoids calling duplicated(rows) if there is no need to check for duplicate row names, when: i is logical attr(x, "dup.row.names") is not NULL (S+ compatibility) i is numeric and negative i is strictly increasing "[.data.frame" <- function (x, i, j,

Conversion of a data frame to a matrix using as.matrix() when a column of the data frame is POSIXt and all other columns are numeric has changed in R 1.9.0 from R 1.8.1. The new behavior issues a warning message and converts to a character matrix. In R 1.8.1, such an object was converted to a numeric matrix. Here is an example. #### R 1.9.0 #### > foo <- data.frame(

Dear all, I am trying to find a suitable R-function for parametric proportional hazard regressions. The package survival contains the coxph() function which performs a Cox regression which leaves the base hazard unspecified, i.e. it is a semi-parametric method. The package Design contains the function pphsm() which is good for parametric proportional hazard regressions when the underlying base

Converting a data.frame with a nested data.frame to a matrix fails: x <- structure(list(a = data.frame(letters)), class = "data.frame", row.names = .set_row_names(26)) as.matrix(x) #> Error in ncol(xj) : object 'xj' not found The offending code is here, in the definition of as.matrix.data.frame (source/base/all.R): for (j in pseq) {

Dear readers of the list, I have a problem a comparison of two data from a vector. The comparison yields FALSE but should be TRUE. I have checked for mode(), length() and attributes(). See the following code (R2.10.0): ----------------------------------------------- # data vector of 66 double data X =

Hi, there, I cannot get accurate value for calculation. for example: ld<-sqrt(1*0.05*0.95*0.05*0.95) 0.05*0.95-ld=-6.938894e-18 0.05*0.95-ld==0 is False. I met this problem in my program, how can I handle it. Thanks. xj.

I have the 'breaks' for the histogram ('hist') but I want weight the cells instead of using actual observations. I thought that using freq=FALSE implied that the numbers in 'x' were weights but this turned out to be wrong. Any help and/or comment is very much appreciated.

I would like to suggest a modification to the make.names() function. The current implementation has two problems: 1. It doesn't check if a name matches an R keyword (like "function"). 2. The uniqueness algorithm is not invariant to concatenation. In other words, make.names(c("a","a","a"),unique=T) !=
