similar to: gsub vs. replace

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

Dear all, I have what is a bit of a confusing question, so I hope that I can explain clearly. Thank you for your help in advance. I would like to do a replacement procedure on several strings, but the way that I am currently going about it is not working. I have defined "len", which is a series comprising the lengths of different items, all preceded by a colon. > len [1]

I just wrote a stupid little JS object to rotate DOM Elements (mainly images) using Prototype and Script.aculo.us as support. Everything seems to work well on IE and Firefox Linux but on FireFox Windows I am getting a slight flash prior to transition. I was wondering if a effects guru could take a quick look and see if anything jumps out. I can live with the flash for my current project but

Is there a standard way of programmatically firing an event on an element? I think this code works in IE but not FF: myElement.fireEvent(''onclick''); I really only care about IE and FF, but anything else is a bonus. I didn''t see anything in prototype/scriptaculous for this, but I might have missed it. Thanks. Joe Athman

Help, please. I need redirection to a custom error page, instead of the default Rails messages (e.g. Unknown action).

Hi , I trying to search and replace all urls on a HTML string using gsub . CODE html = "<a href=''http://site.com.br''><img src=''http://site3.com/ image.jpg''></a><a href=''http://newx.com.br''><img src=''http://localhost/ imagem.jpg''></a>"; pattern = /<a

Hi, I was wondering if anyone has implemented the inplace editor without the need for the URL. I have tried this but run into a problem in that the ''saving...'' text in shown for ever and the label is no longer editable. Can I also confirm that my idea of the callback function is something that runs before the value is passed to the URL (if you were to use one). What might be

Hi, I search a way to replace multiple occurrences of a string with different strings depending on the place where it occurs. I tried the following; x <- c("xx y e d xx e t f xx e f xx") x <- gsub("xx", c("x1", "x2", "x3", "x4"), x) what I want to get is; x = x1 y y e d x2 e t f x3 e f x4 but what I get is; x = x1 y y e

I was reviewing the prototype library (current SVN version) to try to understand the library better. I noticed there are two implementations of the "clone" method on the Position object. There is one before the implementation of the page method and one after. They both appear to be similar actions (copy the positioning from one element to another) although the second implementation

Hello everybody, this might be a trivial question, but I have been unable to find this using Google. I am trying to replace double backslashes with single backslashes using gsub. There seems to be some unexpected behaviour with regards to the replacement string "\\". The following example uses the string C:\\ which should be converted to C:\ . > gsub("\\\\",

Hi all, I'd like to discuss a infelicity/possible bug with gsub. Take the following function: f <- function(x) { gsub("\u{A0}", " ", gsub(" ", "\u{A0}", x)) } As you might expect, in utf-8 locales it is idempotent: Sys.setlocale("LC_ALL", "UTF-8") f("x y") # [1] "x y" But in the C locale it is not:

Omar: I don't think this can work. For example number-letter patterns 4), 5), and 6) would all be matched by pattern 6). As Jeff indicated, you need to provide the delimiters -- what characters come before and after the SKU patterns -- to be able to recognize them. In a quick look at the text file you attached, the delimiters appeared to be either "-" or " " (blank) and

Quick design question. I am trying to get a better understanding of Prototype. While reading through the source I am stumped by form.js. There is a "Field" object and a "Form.Element". Both object seem to consists of a series of actions that making interacting with form fields easier. My question is why two objects? It seems that there should be one object that has this

Hello, I need some help with regex. I have this to sentences. I need to extract both "49MU6300" and "LE32S5970" and put them in a new colum "SKU". A) SMART TV UHD 49'' CURVO 49MU6300 B) SMART TV HD 32'' LE32S5970 DataFrame for testing: ecommerce <- data.frame(a = c(1,2), producto = c("SMART TV UHD 49'' CURVO 49MU6300",

"Please, consider that some SKUs have "-" in the middle, for example: "PG-9021". Then you need to include these in the list of patterns you gave. Try it again -- this time with a **complete** list. -- Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley Breathed in his

Dear group, I need to modify some characters in a data frame. I want to use gsub and the regex functionalities to do this. Here is the data frame (df): DESCRIPTION prix quantity 1 CORN Jul/10 -1.5 0 2 CORN May/10 -1082.0 -3 3 ROBUSTA COFFEE (10) Jul/10 11084.0 8 4 SOYBEANS Jul/10 1983.5

Hi all, please excuse- I'm a complete newbie to R, so it's possible my question was asked a thousand times before, but I don't get it :-( I imported a CSV file via: x=read.csv("test.csv",header=TRUE,sep="\t") In a column there are values with the dot-character (".") I want to replace with a commata: > x[9] ?????????????????? V16 1???????? GPS

there seems to be something wrong with r's regexing. consider the following example: gregexpr('a*|b', 'ab') # positions: 1 2 # lengths: 1 1 gsub('a*|b', '.', 'ab') # .. where the pattern matches any number of 'a's or one b, and replaces the match with a dot, globally. the answer is correct (assuming a dfa engine).
