One of the recurring themes in the recent UserR conference was that many people find it difficult to find the functions they need for a particular task. Sandy Weisberg suggested a small idea he would like to see: a hints function that given an object, lists likely operations. I've done my best to implement this function using the tools currently available in R, and my code is included at the

[This is not about the feasibility of a "hints" function-- which would be incredibly useful, but perhaps very very hard to do-- but about some of the other documentation issues raised in Hadley's post and in Duncan's reply] WRTO documentation & code together: for several years, I've successfully used the 'mvbutils' package to keep every function definition &

Hi listers, I am having some trouble in a matrix multiplication... I have already checked some posts, but I didn't find my problem... I have the following code... But I am not getting the right multiplication... I checked the dimension and they are fine... id_y <- array(1:10,dim=c(2,1,5)) id_yt<-aperm(id_y,c(2,1,3)) m_id<-array(dim=c(dim(id_y)[1],dim(id_y)[1],dim(id_y)[3])) for (i in

I have a simple query as follows: "SELECT m_id,sale_date,YEAR(sale_date),WEEK(sale_date),return_type,DATEDIFF(return_date,sale_date) AS elapsed_time FROM risk_input" I can get, and view, all the data that that query returns. The question is, sale_date is a timestamp, and I need to call split to group this data by m_id and the week in which the sale occurred. Obviously, I would

Dear List members: I'm using R1.7.1 (Windows 2000) and having difficulty with scoping. I've studied the FAQ and on-line manuals and think I have identified the source of my difficulty, but cannot work out the solution. For the purposes of illustration. I have three functions as defined below: fnA <- function(my.x) { list(first=as.character(substitute(my.x)), second=sqrt(my.x)) }

Hi, I'd like to know which functions in a package call one specific function. I think I've seen a tool for identifying such dependencies, but now I can't find it :-( Searches of help and R site search for keywords like function, call, tree, depend haven't helped :-( Can anyone point me in the right direction? Thanks in advance, Keith Jewell

>From the documentation I have found, it seems that one of the functions from package plyr, or a combination of functions like split and lapply would allow me to have a really short R script to analyze all my data (I have reduced it to a couple hundred thousand records with about half a dozen records. I get the same result from ddply and split/lapply: >

Thanks to Andy Liaw, Roger Peng, Thomas Lumley, Brian Ripley and Peter Dalgaard, all of whom addressed my questions or threads arising from them. The full messages were posted to the list so this is a brief summary: Andy Liaw explained the difference between lexical and dynamic scoping and the rationale behind the choice of lexical scoping for R. Roger Peng showed how to modify fnB. Brian

I think ELF could treat it as a Layout-Before reference too. This way Darwin can share the

Hello, pointed to the article "Debugging Without (Too Many) Tears" of Mark Bravington in Rnews Vol 3/3, December 2003 there is a package mvbutils mentioned. So I started to install this package from within R > install.package(mvbutils) I receive an error essage that this package is not found! Is due to a merge,removal or rename of this package? When I try to follow this

Hello Colleagues, I've recently become a fan of Mark Bravington's mvbutils package for organizing analysis projects in a tree. Using cd(), Save(), fixr(), mlazy() etcetera solves nicely some of the nuisances that have worried or annoyed me and sometimes caused big problems over the years. Well thought out. Now one feature that would be fabulous would be automatic time-stamping of

I've inherited a large R codebase which has grown over a few years and a few different developers. It contains many things I'd like to delete: - Unused functions - Variable definitions that are never called - Unreachable code I'd write that myself, it would even be fun, but I don't want to reinvent the wheel. Is there an R package that can find these things? I've heard of

Here is the function that makes the data.frames in the list: funweek <- function(df) if (length(df$elapsed_time) > 5) { res = fitdist(df$elapsed_time,"exp") year = df$sale_year[1] sample = df$sale_week[1] mid = df$m_id[1] estimate = res$estimate sd = res$sd samplesize = res$n loglik = res$loglik aic = res$aic bic = res$bic chisq =

Hi Nick, This would work only if an alias is another name for the same symbol(weak symbols). If what is being aliased is another function definition, which is a non zero sized atom, aliasing will not work. I was thinking to model this for ELF for the below functionalities :- a) __wrap For example : --wrap fn What I plan to do here is, create a undefined function fn atom create a defined

I find the R debug package very useful. I've installed and used it on several of the machines I use, without problems, but on one machine I get the following error: Loading required package: mvbutils Loading required package: utils MVBUTILS: no "tasks" vector found in ROOT Loading required package: tcltk Loading Tcl/Tk interface ... done [Previously saved

Dear useRs, I am experiencing very strange error with Mark Bravington's package "debug". I haven't seen them before.
