similar to: gsub With unicode characters

Dear helpers, I'm trying to replace a character with a unicode code inside a data frame using gsub(), but unsuccessfully. > data.frame(animals=c("dog","wolf","cat"))->my.data > gsub("o","\u0254",my.data$animals)->my.data$animals > my.data$animals [1] "d??g" "w??lf" "cat" It's not that a data

Why are you reporting that your PCRE library does not have something which the R-admin manual says it should preferably have? To wit, footnote 37 says 'and not PCRE2, which started at version 10.0. PCRE must be built with UTF-8 support (not the default) and support for Unicode properties is assumed by some R packages. Neither are tested by configure. JIT support is desirable.' That

The following code: res <- gsub("(*UCP)\\b(i)\\b", "", "nhgrimelanomaclass", perl = TRUE) results in: Error in gsub(sprintf("(*UCP)\\b(%s)\\b", "i"), "", "nhgrimelanomaclass", : invalid regular expression '(*UCP)\b(i)\b' In addition: Warning message: In gsub(sprintf("(*UCP)\\b(%s)\\b",

Hi all Four questions regarding Unicode. Three Windows questions. I am using - a PC with Windows XP (Build 20600.xpsp080413-2111 (Service Pack 3); - the following R version: > R.version platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status major 2 minor 7.0 year 2008 month 04 day 22 svn

In both R and JSON (and many other languages), unicode characters can be escaped using a backslash followed by a lowercase "u" and a 4 digit hex code. However when deparsing a character vector in R on Windows, the non-latin characters get escaped as "<U+" followed by their 4 digit hex code and ">": > x <- "I like \u5BFF\u53F8" > cat(x) I like

Dear list, I am trying to replace Unicode notation of German and Spanish special characters (as read in by read.csv from excel spreadsheets) by character strings that can be interpreted by LaTeX. E.g.: uni2latex <- function(x){ x <- gsub("&", "et", x, fixed = TRUE) # Deutsch x <- gsub("\u0080", "\\\"A", x, fixed = TRUE) x

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:

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 have a problem with unicode & RJS. I searched several boards & blogs, but was not able to find a solution. Let me explain my problem with an example. View (test.rhtml): ... <div id="a_test_div">?????????</div> ... Output: ????????? RJS-Template (an_action.rjs): page.replace_html ''a_test_div'', ''?????????'' Calling

Hi wx guru''s, When I want to display strings with special characters like é (e + /) in a wxRuby gui element, only an empty string is displayed. Not only the ''special'' characters are hidden but all characters! I am using wxRuby on windows XP. It doesn''t matter if I include the special characters directly in the Ruby source code, or read them from an external

I run WBridge5 (French version) under wine-1.1.1 on FreeBSD-7.0. It runs ok except for every UNICODE character is replaced by the little box. Also in some message boxes symbols that obviously should be some French characters that aren't part of normal Latin alphabet are replaced with Chinese characters. How to make UNICODE to display correctly? Thank you, Yuri

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).

I think the problem in R-devel happens when there are non-ASCII characters in any of the strings passed to gsub. txt <- vapply(list(as.raw(c(0x41, 0x6d, 0xc3, 0xa9, 0x6c, 0x69, 0x65)), as.raw(c(0x41, 0x6d, 0x65, 0x6c, 0x69, 0x61))), rawToChar, "") txt #[1] "Am?lie" "Amelia" Encoding(txt) #[1] "unknown" "unknown" gsub(perl=TRUE,

Dear R-users -- I'm using R 1.3.0 on a PC running SuSE Linux 7.1. I'm confused by the following behavior from the gsub() function. Am I doing something wrong? ## A string of characters > string<-c("q","w","e","(",")","q","w","e") ## Use gsub to replace `q' with `A' >
