I suppose it would work, although "=>" is rather a descriptive symbol and less a function. But choosing between quoting: "A + B => C" and a regular function: A + B %=>% C probably quoting is the most straightforward, as the result of the foo() function has to be a string anyways (which is parsed by other functions).

%=>% would have precendence ('order of operations') problems also. A + B %=>% C is equivalent to A + ( B %=>% C) and I don't think that is what you want. as.list(quote(A + B %=>% C)) shows the first branch in the parse tree. The following function, str.language, shows the entire parse tree, as in > str.language(quote(A + B %=>% C)) `quote(A + B %=>%

Hi, I have a rather complex xml document that I am attempting to parse based on attributes: <Manifest xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <!-- eName : name of the element. eValue : value of the element. --> <OutputFilePath>D:\CN_data\Agilent\Results\</OutputFilePath> <FilesList> <File>

Please consider this: <Manifest xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" > <!-- eName : name of the element. eValue : value of the element. --> <OutputFilePath>./XYZ</OutputFilePath> <FilesList> <File> <FileTypeId>10</FileTypeId>

Does LightDM support multiseat setups? For example, I have a PC with multiple graphics cards, monitors, keyboards - used by multiple users concurrently. Will LightDM let me use one PC by many users concurrently (i.e. login screen on every monitor, allowing to start different sessions for different users). -- Tomasz Chmielewski http://wpkg.org

I am having some problems with variable scoping. I need to be able to set a variable that is accessable by other methods within the class (or instance) (i.e not global). An example is 2 pages that change a class variable: class AjtestController < ApplicationController def initialize @@variable = "init" end def show @display = @@variable @@variable = "change 1"

Buenas tardes. Tengo una base de datos con 3200 variables. El nombre de todas ellas tiene un punto. Por ej., Canis.aureus. ¿Es posible cambiar ese punto por un espacio, en todas ellas, de forma automática? Esa quedaría así: Canis aureus Gracias [[alternative HTML version deleted]]

Dear folks: Let?s suppose I want a function to print return the name of the object passed to it. > myname <- function(object) {out<-deparse(substitute(object)); out} This works fine on a single object: > O1 <-c(1:4) > myname(O1) [1] "O1" However it does not work if you use lapply to pass it the same object from a list: > O2 <-c(1:4) > object.list <-

Hi all, Roger Peng and Jason Turner's suggestion with ImageMagick seem to be the simplest "dirty" way to get the problem solved. But I ran into yet another interesting but quite round-about way to solve the problem (partially). Through tcltk package, one can read in the gif image with > x <- tkcmd("image", "create", "photo", file=mypic.gif)

Dear all, i have a dataset of about 400 records , with a variable that has  two levels 40 bad and 360 good among other variables,how do i come up  with10 random samples that have the composition of as the main sample  but maintaining the 40 bad 360 good with replacement, i recently discovered that my random samples generated dont maintain the ratio. My code is as  : mysample <-

Hola, gracias por la respuesta, No me funcionó debido a que los nombres de las variables no están seriadas, es decir, los nombres de las variables son del tipo: x23 x25 x30, x301 x320, x80. Entonces me da este error: Error in eval(predvars, data, env) : object 'pot24' not found. Debido a que pot24 no existe, ya que de pot23 se brinca a pot30. En Stata es algo muy simple de hacer, solo

I have a 5 column matrix like 12 10 8 6 3 10 9 8 7 5 14 NA 4 NA NA NA 15 NA 10 NA 5 ... I want to select the position of the first entry for each row <=5 for example, for the first row, I want to select the last element and return its position as 5; for th e third row, I want to select the third element and return its position as 3; similarly for the 4th row, I want to select the fifth

Dear R helpers: I like to apply deparse(substitute()) on multiple arguments to collect the names of the arguments into a character vector. I used function test.fun as below. it works when there is only one input argument. but it does not work for multiple arguements. can someone kindly help? test.fun <- function(...){deparse(substitute(...))} test.fun(x) #this works test.fun(x,y,z) # I like

Trying to run this exec in one of our manifests. When the resource is run during a puppet run, it returns a error code 87. But when I execute the same command on command prompt, it returns 3010. Is there any way to dig and and find out why the return codes are different. FYI, I am using the sysnative path to avoid the file system redirection on windows. Platform: Windows 2008R2 64 bit

It took me a while to track this down. I am using MIT Kerberos 1.4.3 and libgssapi-0.7. With some patches that came with Suse 10, but that doesn't appear to be relevant. I have been using openssh-4.2p1 (with Simon's patches) and openssh-4p3p2 out of the box. I see the same problem no matter which version of openssh I am using. I am using two Suse Linux x86 boxes as a test

Hi, Well - having in mind this is "flac-dev", I thought you are a developer and writing an application for that purpose is quite trivial. Anyway, CUE sheets are so simple, they can even be written by hand - the minimal CUE sheet is very simple. About the actual embedding - I haven't worked with metaflac or editing applications so I can't give you any specific advice for that.

Sorry - working on a simple tutorial but something is throwing me here. I''m supposed to get a Time.now() print to the page but it''s not working and I can''t figure out why. No errors are thrown my the page shows: Howdy, world! My name is Stuart Felenstein. This was verified at . So no time stamp showing. I went into IRB , did a Time.now() and it''s working

Hola a todos Primero que todo, gracias por todos los consejos, me han servido ene. Mi pregunta es la siguiente: Como armar una función lógica "SI" PARA CAMBIAR LOS NOMBRES A LOS HEADER Por ejemplo, si tengo una tabla así; a b c d 1 3 4 6 2 4 6 7 a= "pluvio mensual" b= "carga de batería" c= "temperatura" d= "radiación". La idea es
