R Community, I often am in need of viewing the reference manuals of packages and do not have Internet access. I have used the code: path <- find.package('tm') system(paste(shQuote(file.path(R.home("bin"), "R")),"CMD", "Rd2pdf",shQuote(path))) someone kindly provided from this help list to generate the manuals from the latex files. This

Hello R community, This isn't a technical question about R: I have used http://lib.stat.cmu.edu/R/CRAN/ as my mirror for some time now. As of a few days now I don't seem to be able to use this mirror. The link from CRAN to this repository does not work either. Does anyone know the fate of this repository? Cheers,Tyler Rinker If this was not the appropriate place for this question

I have a long equation that I need to break in the R documentation of a package or it trails off the right hand side of the page. Here's the formula: \deqn{Cov(r_{ist}, r_{iuv})= [.5\rho_{ist}\rho_{iuv}(\rho_{isu}^2 + \rho_{isv}^2 + \rho_{itu}^2 + \rho_{itv}^2) + \rho_{isu}\rho_{itv}+ \rho_{isv}\rho_{itu}-(\rho_{ist}\rho_{isu}\rho_{isv} + \rho_{its}\rho_{itu}\rho_{itv}) +

Greetings R community, I am making my first package and have run into the need to use other packages. I pass all the checks in the command prompt running Rcmd check package.name. In the Description file I have included: Depends: R (>= 2.13), plotrix Repository: CRAN Now I create the zip file for windows 7. I delete my plotrix package from my library to create a setup where others

Good Afternoon R Community, I often work with very large data bases and want to search for select cases by a particular word or numeric value. I created the following simple function to do just that. It searchs a particular column for the phrase and returns a data frame with the rows that contain that phrase (for a particular column). Search<-function(term, dataframe, column.name,

In my R learning I've come across a situation in which a piece of code that works on the work space outside a function does not work inside the function. WARNING THIS EMAIL CONTAINES THE CODE:#rm(list=ls()) THIS WILL CLEAR ALL OBJECTS FROM YOUR WORKSPACE! When I use rm(list=ls()) and then ls() it shows character(0) So I tried to make a quick function to speed this up as follows:

R Version 1.9.1 (2004-06-21) Mac OS X.3.5 Dual 2GHz PowerPC G5 GUI = "AQUA" I have a data.frame comprising percentiles with the column headings containing % characters, e.g. > (pp <- colnames(temp2)) [1] "5%" "10%" "25%" "50%" "75%" "90%" "95%" I use xtable to convert the data.frame to Latex but I want to

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. Or am I just blind? Best, Torsten R> version

Greetings R Community, I am working with the ifelse function and it is returning something unexpected. In the code the line with the MODE1 assignment the output is a vector [1] 4 5 6 but when I put the MODE1 object into the ifelse function [R}'s output for MODE1 is the first number from the string (4). Why is this? Given the supplied vector of x I would assume both the MODE1 and ifelse()

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("\\\\",

I was using tagPOS function from openNLP package for parts-of-speach. Now the package is updated and the function is not present. Any suggestions how to do it now ? Thanks for your help. -- Regards, Siddharth Arun, Contact No. - +91 8880065278 [[alternative HTML version deleted]]

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

Simple question but searching rseek did not yield the results I wanted. Question: Is there a way to open a help manual for a package from within R. For instance I would like to type a function in r for the tm package and R would open that PDF as seen here: http://cran.r-project.org/web/packages/tm/tm.pdf -The vignette function exists for vignettes [vignette("package.name")] so I

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 \"

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("&",

Hello R Community, I'm continuing to work through logistic regression (thanks for all the help on score test) and have come up against a new opposition. I'm trying to compute Somers Dyx as some suggest this is the preferred method to Somers Dxy (Demaris, 1992). I have searchered the [R] archieves to no avail for a function or code to compute Dyx (not Dxy). The overview of Hmisc has

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

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
