similar to: Removing backslashes from data

Is it just my installation or does edit() (or fix(), etc.) in R-4.0.0 double all the backslashes when options(keep.source=TRUE)? E.g., > options(keep.source=TRUE) > f <- function(x) { cat("\t", x, "\n", sep="") } > edit(f) # exit the editor without making any changes The editor (vi or notepad) shows doubled backslashes function(x) {

Hi, all. I've been searching google, bug reports and forums and have looked in all the asterisk-users list archives back to 2003 but haven't seen an answer to this, so thought I'd post here. The problem seems to be that Asterisk 1.6.0.5 is sending backslashes (needed to escape commas and so forth in 1.4.21.2) as *literal* backslashes to Mysql, so that Mysql gives a syntax error

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("\\\\",

I find that Sys.glob() doesn't like UNC paths where the initial slashes are backslashes. The help page for Sys.glob() doesn't specificly mention UNC paths, but does say: "File paths in Windows are interpreted with separator \ or /." Is the failure to treat a path beginning with a double-backslash as a UNC network drive path the intended behavior? E.g., on a Windows system

Hello! I've just started trying gnome-terminal (instead of xterm) because of its "tabbing" facility. However, I note that with it backslashes appear something like a W with a horizontal line through it. Any known way to get a backslash to appear as a backslash? To see what I mean, use gnome-terminal with echo '\' in bash, ksh, etc. Regards, Chip Campbell

Dear R List I have a small problem concerning the output of print().

Dear developeRs, I thought that backslashes can be escaped in the usual way (and I think I did this before) but I can't see why R> gsub("\\", "x", "\alpha") Error in gsub(pattern, replacement, x, ignore.case, extended, fixed, useBytes) : invalid regular expression '\' gives an error.

Hello, I've seen this question asked in the archives but no clear reply or solution provided. So, just to be sure it is not possible in R: Can I replace backslashes with slashes in a string ? I am writing a GUI for R with the Rpad library. I have a "browse" button for data loading and Windows return a path string with backslashes. I need to convert them into slashes to use the

Full_Name: Magnus Torfason Version: 2.7.0 OS: Windows Vista Submission from: (NULL) (128.59.140.167) Each time a string is edited in the data editor (on Windows at least), any pairs of backslashes (an escaped backslash) are duplicated on each edit of the string. Note that one must actually double click the value for the bug to show up. Behavior/Replication: > # Create data frame >

Hello Everyone, I am an avid Sweave user and I am trying to pretty print floating point numbers for latex output. For example in my document, I would like: 4.2\cdot 10^-{8} Instead of: 4.2e-08 The Hmisc package has a nice function for doing this- but Hmisc has a ton of dependencies and has proved very unportable to the various machines I work on. So, I set out to write my own function that

Hi R-devels, I noticed that you are working quite actively on the new Rd-parser and have made it the default renderer in R-2.10.0dev. So I would like to come back on an issue I have already raised on this list last November ("Two minor escaping issues using \preformatted{....} in Rd format") My setting has slightly changed as \preformatted, AFAICS is not supported within \describe

Hi, Back in June I posted the message below, but had no replies. I've made a little progress since then so this is to update anyone interested (!) and to ask for comments. Brief problem statement: Under Windows, some parts of R don't handle UNC paths beginning with backslashes. Specifically a) Sys.glob() fails to find some files breaking (e.g.) Rcmdr plugins

I'm comparing R-1.3.0 on Solaris 2.6 to R-1.3.1 on WindowsNT. The following 5-line script returns TRUE on Unix but FALSE on NT: fnam <- tempfile() file.create(fnam) txt <- paste("file.exists(\"", fnam, "\")", sep="") expr <- parse(text=txt) eval(expr) The issue seems to be that backslashes get lost in the parsing. A workaround is to change

Something about the way R processes backslashes is defeating me. Perhaps this is because I have only just started using R for text processing. I would like to change occurrences of the ampersand & into ampersand preceded by a backslash. > temp <- "R & D" > sub("&", "\&", temp) [1] "R & D" > sub("&",

Greeting R Community, I am a windows user so this problem may be specific to windows. I often want to source files from within R such as: C:\Users\Rinker\Desktop\Research & Law\Data\School Data 09-10. To source this file I need to go through the path and replace all the backslashes (\) with forward slashes (/). I usually do this in MS Word using the replace option, however, I'd like

I've just started using AMP and found that I have a problem with escaped characters in config files. In particular, I have a custom config item that needs a semicolon in... SetVar(_ALERT_INFO=info=auto-answer;delay=1) To get the part of the line after the ; to be accepted by Asterisk as a non-comment it needs to be escaped with a backslash, but I have found that I need to put two

The following code works, to gsub single quotes to double quotes: line <- gsub("'", '"', line) (that's a single quote within doubles then a double within singles if your viewer's font is not good). But The R Language Manual tells me that Quotes and other special characters within strings are specified using escape sequences: \' single quote \"

I can confirm this changed behaviour. I just compared R-3.6.3 with yesterday's R-devel. Using R-devel, the tempfile opened by the editor (Emacs for me, but shouldn't matter) contains doubled backslashes.

Hi, I'm trying to build a vector of latex commands. However, I need the command strings to begin with a backslash "\". I have: test <- c('foo','bar') and I need to rebuild the array, encapsulating the text items with latex stuff, like this: paste("\parbox[b]{3cm}{", test, "}", fill=TRUE) Actually, cat() prints the string fine if one uses

Dear list, After searching many old posts, I can't find the solution to a simple problem. can someone tell me how to create a character string with multiple backslashes, as in: file_dir <- c("C:\files\data\") I need to create this string and then paste it to many files names for batch processing in another software program. R won't accept the backslash and removes
