Dear list, I cannot make the latex command to output a ftable objet the way I want it. Is it posible? I found a post in the archives saying that one should use the rgroup and n.rgroup arguments to supply the row names, but so far I have been unsuccessful. This is what I have: >

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

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("\\\\",

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

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("&",

Frank Harrell rote in a message dating from Oct 8th: > n.group is an argument to latex.default in the Hmisc package I must admit that I can't find it in the function head, which reads on my installation: function (object, title = first.word(deparse(substitute(object))), file = paste(title, ".tex", sep = ""), append = FALSE, label = title, rowlabel = title,

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 \"

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.

How can I get a single backslash in a character string? My goal is to escape dots in a string that will be used as a regular expression. I thought I could do it this way: gsub(".", "\\.", x) Unfortunately, "\\" does not represent a literal backslash as I expected, but rather a pair of backslashes: > "\\." [1] "\\." > "\\" [1]

I am in the middle of migrating a number of applications from one server to another and I am running into an issue with backslashes on a smbfs mount. Basically, the backslash can be used in a file path on the old server and not on the new. This turns out to be important because of the samba share is used to store data for a large number of FTP clients, who use an old automated script which chokes

Hi, I am trying to consume a web service that returns a JSON string, however, when I run > fromJSON(s) Error: '\/' is an unrecognized escape in character string starting "http:\/" because the string s contains a single backslash, which is the JSON escape character, but R expects 2 backslashes, I think. Is there anyway to preprocess the JSON string returned from the web

Why sometimes one has to put a double backslash in regular expressions, but often simple backslashes work too? Is only a \ required for giving a metacharacter its usual meaning? --------------------------------------- u=grep('\\{[\\-u]x',a,perl=T) # equivalent to u=grep('\{[\-u]x',a,perl=T) # but u=grep('\w',a,perl=T) # is not correct and requires

Hello, [really hoping not to ask something the 1001th time] I need single backslashes printed for generating TeX-code. That works: > print("\begin{tabular}") [1] "\begin{tabular}" But \h seems to be interprated in some way: > print('\hline') [1] "hline" Hm, trying to mask the backslash: > print('\\hline') [1]

I am trying to check for backslashes in data, then remove them when I find them, but am having a difficult time figuring out the best way to do it. I know the backslash is the escape character in R, and I should be able to use 'gsub' to accomplish this, but I all I seem to be getting are errors. For example: If entry is: "Hello\World" I want: "HelloWorld"
