similar to: RFE: vectorize URLdecode

Dear all, I am aware of the URLdecode(..) function and was wondering if there was something similar for HTML? For example, I would like to convert strings like this: > x <- "isn&apos;t" into this: > "isn't" Many thanks for your time, Tony Breyal # O/S: Windows Vista 32 bit # R version 2.11.0 (2010-04-22)

Hi, On Windows, with last R-devel tarball (r40647) from ftp://ftp.stat.math.ethz.ch/Software/R/R-devel_2007-02-04.tar.gz I get the following build error: E:\biocbld\bbs-2.0-bioc\R\src\gnuwin32> make ... ... ---------- Making package utils ------------ adding build stamp to DESCRIPTION installing NAMESPACE file and metadata installing R files Error in namespaceExport(ns, exports) :

Dear useR, Just wandering whether it is possible that there is any function in R could let me get the text contents for a certain website. Thanks a lot! Best, Leon [[alternative HTML version deleted]]

This is a best practices / style question. The way I use RODBC is I something like this: > foo <- sqlQuery(db, "select * from foo") > apply(foo, 1, function{...}) That is, I use apply to iterate over each result -- row -- in the RODBC-produced dataframe. Is this how one generally wants to do this? My concern is that when apply iterates over the rows, it uses as.matrix()

I know that if I have a function that returns multiple values, I should do return(list(foo, bar)). But what do I do on the recieving end? fn <- function(x) { return(list(foo, bar)) } I know that at this point I could say values.list <- fn(x) and then access values.list[1] values.list[2] But that's hideous. I'd rather be able to say something like list(local_foo, local_bar)

I have a named vector: > z <- c(1, 2, 3, 2) > names(z) <- c("a","b","c","b") > f <- c("b","c") I want to know the index in z of the first occurrence of each of the values in f. One implementation is > sapply(f, function(x) which(names(z)==x)[1]) b c 2 3 Is which() smart enough to stop when it finds in z the

I'd like to have something like seq() where I can pass in a length of the desired sequence and a right limit so that the sequence goes up to the limit and then starts again from 1. # works now seq(from=2, length.out=3) [1] 2 3 4 # what I want seq(from=2, length.out=3, rlimit=3) [1] 2 3 1 # additional examples of what I want seq(from=2, length.out=4, rlimit=3) [1] 2 3 1 2 seq(from=2,

The following three calls all produce the same result (my machine is in EST): > as.POSIXct(0, tz="", origin=ISOdatetime(1970,1,1,10,0,0)) [1] "1970-01-01 10:00:00 EST" > as.POSIXct(0, tz="EST", origin=ISOdatetime(1970,1,1,10,0,0)) [1] "1970-01-01 10:00:00 EST" > as.POSIXct(0, tz="GMT", origin=ISOdatetime(1970,1,1,10,0,0)) [1]

(Using BRugs 0.7-5, R 2.14.2 32-bit on 64-bit Windows 7, OpenBUGS 3.2.1) 1. BRugs crashes R for me as follows.

> a <- sqlQuery(irrdb, "select count(field) from mytable where field = 1") > print(a) count(field) 1 8 > paste(a) [1] "as.integer(8)" Why the as.integer() representation? I later pass the result into this write.html.table(), and what I get is rows of as.integer()... when all I want is the integer itself. as.integer(31) as.integer(21)

Hi all, I need your opinion about using R-Rapache to build a knowlegde base to bioinformatics field. I have copious amount of genotype information (some few million records) and would like to store it in MySQL database. Then, using RMySQL connector I would like to use it for further analysis using R over a web interface. The web interface which I am thnking off, just does not serve the purose of

I am trying to set up a RApache server on my Ubuntu 8.04. I have installed apache2, R-2.7.0, and the RApache plugin. Both Apache and R seem to work fine, but whenever i try to use the plugin i get this error: C stack usage is too close to the limit. I have tried to recompile apache2, R, and RApache, but i keep getting the error. The weird thing is, i had exactly the same problem when i installed

Hi, this is Charlie and I am trying to embed R in my apache server. However, I am having problem with installation. The R projet says that we can install add-on package with command $R CMD (rapache.0.1.4.tar.gz). However, I try to use it in command windows (windows xp) and an error shows. Please tell me when I can use the command (in c?? or in the same folder with the file). thx. [[alternative

dear r-community, currently i have a workflow as following: data in online-MYSQL-database via .csv into R for analysis, results back to mysql. generating graphics for reports also. that's ok, but i need some process-optimization. i'd like to run r directly on the webserver. analysis should work automatically, after the appropriate r-script was selected in a browser-gui for R. until

Hello, The use of .Call and the like all depend on loading shared libraries and registering routines from it. Also, .Primitive and .Internal depend on routines being registered in the R binary. And applications that embed R can override routines declared in Rinterfac.h, but is there a way for an application embedding R to register other routines defined in the application without loading a

Hello, I submit a patch for review that implements code coverage tracing in the R interpreter. It records the lines that are actually executed and their associated frequency for which srcref information is available. I perfectly understands that this patch will not make its way inside R as it is, that they are many concerns of stability, compatibility, maintenance and so on. I would like to have

Hi, right now we have (on R v2.7.0 patched (2008-04-23 r45466)) that: > rawToChar(raw(0)) [1] "" > rawToChar(raw(0), multiple=TRUE) character(0) Is this intended or should both return character(0)? Personally, I would prefer that an empty input vector returns an empty output vector. Same should then apply to charToRaw(), but right now we get: > x <- character(0) >
