Dear useRs, Here is a weird behavior of transform function: mtcars1<-matcars transform(mtcars1,t1=3,t2=4) Error in data.frame(`_data`, e[!matched]) : arguments imply differing number of rows: 32, 1 instead, this works: mtcars1$t1<-0 transform(mtcars1,t1=3,t2=4) also works if applied in turn: transform(mtcars1,t1=3) transform(mtcars1,t2=4) I often need to use this

Dear Developers, In current implementation of validity method, objects are first coerced to superclass (slots are striped). Thus, it is not possible to write validity method which would perform some checks on children slots. Say, I want to check if number of slots in a class is equal to "n": setClass("A", representation(a="numeric", n="integer"),

Hello everyone, I am trying to implement completion for proto objects. Proto extends environment in a hierarchical way. Thus completion should list all the names in all it's parent environments. For "normal" classes defining names.class would do the job, but completion for "environment" is hard coded in utils:::specialCompletions by means of base::ls(). As result

Hi, Browser doesn't work properly with the compiler enabled. It might be intended behavior, but it's not documented. compiler::enableJIT(1) foo <- function(){ browser() cat("here\n") } Browser doesn't stop, and I am getting: > foo() Called from: foo() Browse[1]> here > Thanks, Vitalie. > sessionInfo() R version 2.14.2 (2012-02-29) Platform:

I think it would be beneficial to designate an official UTI (see http://developer.apple.com/macosx/uniformtypeidentifiers.html) to be used on OS X for FLAC files. I have written a FLAC metadata importer (http://sbooth.org/importers/) for which I chose the UTI 'net.sourceforge.flac'. A standard UTI for application developers to use would help alleviate any confusion and could

Dear Rsync Users, Please can I have a bit of rsync advice? I am trying to rsync a file called. 'Draft text - with Holley comments.doc' from machine a to machine b. Unfortunately this isn't working because I think rsync recognises the - character and thinks it's an option. I have tried escaping this out as well as putting it all in " " but neither seems to work

Hi, This is a very simple question I realise, but I hope maybe someone can just help me out. I am trying to do a very simple thing, just transfer a file from machine A to machine B using rsync with ssh. This is what i'm typing: bash-2.03# rsync -avvv --rsh="ssh -l tdf" tdf@machine.niss.ac.uk:/export/home/tdf/demofile.html demofile.html This is what I get: opening connection

Hello, I am having difficulty filtering a data frame. I would like to take all the rows of a data frame where column A contains the regular expression "UTI" (or some other regex). Here's what I've got: utiRE <- function (avector) { occurs <- c() r1 <- "UTI" for (x in avector) { if (!is.na(grep(r1,x,perl=TRUE))) { occurs <- c(occurs, TRUE) } else { occurs

Hi, I am fairly new at Rails, and attempting to deploy an application that''s running fine using InstantRails on my PC. On the deployment server (I use railsplayground.net), I get the following error: Processing ApplicationController#index (for 220.224.229.156 at 2008-06-25 18:49:34) [GET] Session ID: 5921e7d789ee3aaa214f2d59aa40986a Parameters: {"action"=>:index,

Hi: I have a function as follows: my.plot <- function( x, y = NULL, ... ) { plot( x, y, cex.axis=0.5, ...) } Set up the variables: x <- 1:10; y <- x; tdf <- data.frame( x, y ); main.str <- "test" I will exercise the function in two ways: > my.plot( y ~ x, tdf, main = "test" ) This works fine > my.plot( y ~ x, tdf, main = main.str ) Error in

I've got two WinXP SP2 users. Roaming profiles. One of them takes about 25 seconds to log out unless she has made pretty drastic changes to her profile (My Documents, etc). My second user takes upwards of 3 minutes to log out, even if he has just logged in, not opened a thing or made changes, and then logged back out. Below is part of a strace as I don't know what I'm looking

Dear UseRs, For various reasons I need to plot multiple ggplots on one device (preferably pdf). Is there a way to achieve that? par(mfrow), split.screen() and layout() seem not to do the job. Thanks, Vitalie.

Hello, I am forwarding this from ESS mailing list, as it's a failure of internal R completion system: This fails: utils:::.assignLinebuffer('iris[iris$Spec') utils:::.assignEnd(15) utils:::.guessTokenFromLine() utils:::.completeToken() utils:::.retrieveCompletions() ## -> [1] "iris[iris$Spec" This works utils:::.assignLinebuffer('iris[ iris$Spec') # note the

Hi all, As some of you might know, the FLAC format is being processed by an IETF working group to become an internationally recognized standard. Part of this process is FLAC being assigned a media type (also known as MIME-type by many): audio/flac. However, during review of the application, it was requested to include a UTI and a Windows Clipboard Flavour Name. Now, apparently the latest macOS

Disclaimer/Apology: I am an R newbie I am seeing some behaviour that seems to me to be the result of some cacheing going on at some level, and perhaps this is expected behaviour. I would just like to understand the basic rules. What I have is a file with some data. I read it in and then do a summary on the resulting dataframe. I find the some values are completely outside the expected range,
