R-helpers, I have a vector of character strings in which I would like to replace each parenthetical phrase with a single space, " ". For example if I start with x, I would like to end up with y. x <- c("My toast=bog(keep=3 no=4) and eggs(er34)omit=32", "dogs have ears", "cats have tails (and ears, too!)") y <- c("My toast=bog and eggs

Hi Newbie question: I have a set of data frames that I want to do the same calculations on each. I've found out that I can put them in a list and loop through the list to do the calculation, but not put the results back into each data.frame.. For example three data frames cats, dogs, birds where >cats name eats_kg 1 bob 3 2 garfield 4 3 chuck 6 and dogs and birds are similar but not

Hi all, Suppose I had the below example where a survey was carried out recording the number of each type of pet in each house count<-c(2,1,2,1,2,3,4) house<-c("house1","house1","house2","house3","house4","house4","house4")

Hello. I''ve read about examples on inheritance with rails. Here is an example: http://juixe.com/techknow/index.php/2006/06/03/rails-single-table-inheritance/ The way is to add a type field in the table. So if I have an Animal class with an attribute name, I can inherit from this class like: Dog < Animal, Cat < Animal, and so on. With the type field in the table I can do Dog.all,

Hi, I began experimenting with habtm relationships, and so I created a stories table, a tags table, and a stories_tags table referencing the former 2. When I create a "story", I want to add several tags to it. Then, the model should create those tags and link them to the respective stories, and for the tags that already exists, just link them to the story. I tried something like

Hello, R friends, I'm trying to crack this nut: Example Data. pet    gender dog    male dog    female dog    male cat    female cat    female cat    male Plot Task. Horizontal 100% bars where y axis shows gender factor (male vs. female) and x axis shows percentage of kind of pets (dog vs. cat) so that % dogs + % cats are stacked in 1 bar and sum up to 100% (for each gender group 1

You asked in the Vorbis list, but your text only mentions OGG. The codec commonly used in OGG containers that is limited to 48 khz is Opus. Maybe you are trying to use the wrong codec (i.e. Opus instead of Vorbis)? Using a 44.1 khz wav file, I was able to encode a 192 khz ogg-vorbis file with the following command: $ oggenc --resample 192000 input.wav Of course, if your original material is

Hi, I have several data sets which are all approximately within the same values as each other (both X and Y) and all of these data sets more or less overlap each other when plotted on the same graph. However, although each data set varies between approximately the same range, there are vastly different numbers of data points within each data set (due to the nature of how these values had to be

I am appealing to the general collective wisdom of this list in respect of a statistics (rather than R) question. This question comes to me from a friend who is a veterinary oncologist. In a study that she is writing up there were 73 cats who were treated with a drug called piroxicam. None of the cats were observed to be subject to vomiting prior to treatment; 12 of the cats were subject to

(new asterisk user - currently setting up Polycom IP600 phones) Does anyone know if it's possible to make a sip phone instantly pick up on speakerphone when a particular call comes in? Eg so that you can quickly bother someone across the office without making them reach for their phone?

Hello, I plan to use a script with R CMD BATCH on different platforms Linux, Windows and Mac OSX. I use the commandArgs(trailing = FALSE) function to retrieve the name of the script and the arguments (example below with output.) The online docs for "Introduction to R" (sections B.1 Invoking R from the command line and B.4 Scripting with R) and help("commandArgs")

I use Windows, R version 2.4.1. I have a dataset in which columns 1-3 are replicates, 4-6, are replicates, etc. I need to calculate an average for every set of replicates (columns 1-3, 4-6, 7-9, etc.) AND each set of replicates should be averaged every 14 rows (for more detail, to measure fruit color using a spectrometer, I recorded three readings per fruit -replicates- that I need to average to

In my daily development, I migrate back and forth between versions, and often do: rake load_fixtures... ... in order to populate my development database with fun data. Now, with any HABTM relationship, there are failures, as there is no way to say "which" fixtures to load first. Within an actual functional or unit test case, you could simply load them in the proper order, but

Say I have the following three tables: dogs ------- id (PK) name cats ------ id (PK) name recipies ----------- id (PK) recipie_text I''ve made a model for each of them: Dog, Cat and Recipie. Now I want to create a model, Cookoff, that will contain arrays of Dog, Cat and Recipie objects. There is no associated database table for Cookoff because it''s merely a container for a

Dear all, I have a data frame containing the results of an experiment. Like this: a<-seq(1,4,by=1) b<-seq(1,2,by=1) test<-expand.grid(b,a,a) colnames(test)<-c("replicates","bins", "groups") test$abc <- rnorm(32) test$def <- rnorm(32) test$ghi <- rnorm(32) test The following code snippet aggregates the data for one variable and then draws a

Hello, The dataset "cats" contain information about the heart weight ("Hwt"), body weight ("Bwt") and gender ("Sex") of a group of 144 cats. I write the following piece of code: library(MASS)attach(cats)ratio <- Hwt/Bwtmale <- ratio[Sex == "M"]female <- ratio[Sex == "F"] My question is, when I look at the object

Hi: I am trying to create a dynamic latex table using \Sexpr{} but it's not evaluating it. I also tried the example below without Sweave and also fails. I have also copied the Sweave.sty to my working directory but nothing seems to work. Do I need to have certain package in order to run \Sexpr{}? \documentclass[a4paper]{article} \usepackage{C:/R/R-2.8.1/share/texmf/Sweave} \begin{document}

I wish to do a stacked area chart to show how relative proportions of species within a stand have changed over time. I know this is simple, but can someone point me to the right function (if it exists). I have not had any luck finding it in the R-help, but maybe I am searching using the wrong keywords. Thanks, Mike Mike Saunders Research Assistant Forest Ecosystem Research Program Department

Hola Tengo un problema con Sweave y xtable, concretamente quiero cambiar el color según un criterio, creo que es más fácil explicar con los siguientes ejemplos, uno puede correr directamente porque es R, al siguiente código hay que guardarlo como Rnw, y luego puede ser corrido en R, donde seguramente al correr este se darán cuenta de mis dos problemas porque saltan al abrir el pdf que se obtiene

Just when I started getting the hang of has_and_belongs_to_many relationships, I realize that I should probably convert several of my app''s joins to has_many :through type relationships. One example, pairing users with categories via subscriptions, where each user can be the "owner" of a category, has given me particular trouble when I try to update a user''s
