Friends I need to get R reading from a fifo. I want it to block till there is some data in the fifo, consume what input it gets there, do some thing with it then loop back and block again. Very simple. Yes? No. The example in the documentation works OK.. zz <- fifo("foo-fifo", "w+") writeLines("abc", zz) print(readLines(zz))

Hello, I must tell you once again to address your questions to r-help at r-project.org And since there was no subject line, I've made up one. Your question seems to be a question about excel, and I really can't help you. Maybe someone else can. But if you write.table(etszP) can't you read that file into excel?

Hi, I am trying to run some R commands into my bash scripts and want to use shell variables in the R commands and store the output of R objects into shell variables for further usage in downstream analyses. So far I have managed the first, but how to get values out of R script? I am using "here documents" (as a starter, maybe something else is simpler or better; suggestions greatly

Trying to use R to build an interactive "slide show", to be displayed on a projector. The purpose of the presentation is to show how one could construct a simple graph using R. It is meant as a general overview rather than as detailed instruction. For example, something like the following sequence of commands. At lecture time, I want the interpreter to read these commands one at a

Dear List, I have the code below adapted from the lattice-package examples to draw two spheres. I would now like to give both different surface colors, e.g. one red and one blue. ## 3-D surface parametrized on a 2-D grid n <- 10 tx <- matrix(seq(-pi, pi, length.out = 2*n), 2*n, n) ty <- matrix(seq(-pi, pi, length.out = n) / 2, 2*n, n, byrow = T) xx <-

Hi all, I am whitening my data: # code begins N <- 300 M <- 2 x <- matrix(data=rnorm(N*M, 0, 3)-10, ncol=M, nrow=N) y <- matrix(c(1,-2,-2,1), ncol=M, nrow=M) z <- data.frame(x %*% y) colnames(z) <- c('x','y') par(mfrow=c(1,3)) plot(z, pch=5, col="blue") whiten <- function(x) { (x-mean(x))/sd(x) } zz <- transform(z, x=whiten(x), y=whiten(y))

Hi all, I have a problem with a variable created by a SELECT CASE statement. See the code below. I would like the variable "event" to be a character variabel as I want to UNION my two SELECTs - and the "event"-variable is a character variable in the first SELECT result. I have tried different ways: * used ' ' in stead of " " around the string I want as the

I am trying to write a function that can be used to apply to process all the columns of a data.frame. If you will run the code below, you will get the error message undefined columns selected.

Hi list, I have a shorewall installed on 2 interfaces which also has multiple static public IP. Let''s say I have 1.2.3.4 and 1.2.3.5. I have assigned nat with: 1.2.3.4 eth0 11.22.33.4 no no But then I have a situation where I need 11.22.33.44 to connect to a host in the net zone and appears also to be 1.2.3.5 not only 1.2.3.4. How to do it? TIA Willy

I have been racking my brain attempting to get the remote callerid information for calls made to extensions on another Asterisk system connected via IAX2 but nothing has worked. To clarify, I would like to display the number AND name on the calling phone when calling extensions on another Asterisk system. I seem to be able to 'send' all the information I want to the system I am calling but

Would someone be able to give an example of a working use of setvar from chan_dahdi.conf? I am trying to create a custom variable like I use in sip.conf but I have been completely unsuccessful getting any variable set using setvar to appear for a DAHDI channel. I am running 1.8.11-cert8 and am using the newer format (but I have tried using the older [channels] format). Here is an example:

I was recently asked by one of new colleagues how to combine, or catentate, or concatentate two factors. If x and y are factors, doing c(x,y) appears to coerce x and y to numeric mode before catenating them. So what does one do if one wants the result to be a factor whose levels are the union of the levels of x and y? I vaguely recall seeing this discussed in r-help, but I can't find

I have some comment text taken from a SAS data file. It is stored in two vectors and is difficult to read. I would like to simply concatentate the individual entries and end up with a character vector that give me one line of text per comment. I cannot see how to do this, yet it must be very easy. I have played around with cat() and print with no success. Would someone kindly point out where I
