hi, get.vars.name.prefix<-function(prefix){ result<-list() len<-nchar(prefix) var.names<-ls(name=1,pattern=prefix) #name=1 probably wrong option print(var.names) for(i in 1:length(var.names)){ name<-var.names[i] field<-substr(name,len+1,nchar(name)) result[[field]]<-get(name) } result } for example x.1<-1 x.2<-2 get.vars.name.prefix("x.") should

hello, the example below does not work. (i know it's not supposed, but it makes it clear what i'm trying to achieve) par(mfrow=c(2,1)) xyplot(y~x2|x1,data=dataframe1,pch=20) xyplot(y~x2|x1,data=dataframe2,pch=20) i know i could probably merge the two datasets and do something like xyplot(y~x2|x1+dataset,data=merged) any other suggestion? thanks.

Hello, My app needs to know where to store files but the path is different for dev and production. What is the best way to do it? - something like $path = ''/home/myrailsapp/public/files/'' in development.rb and $path = ''/home/my_remote_prod_sapp/public/files/'' in production.rb? - do a test to check the env and add the path in application.rb? - do a test to

Hi All, Is there a way to get event notification for zfs filesystems and snapshot creation/deletion ? I looked at HAL and event ports but couldn''t find anything. Does such a feature exist for zfs ? Thanks in advance, Erwann -- Erwann Ch?ned?, Desktop Group, Sun Microsystems, Grenoble

hello, i need help with: data$f1<-as.factor(data$f1) data$f2<-as.factor(data$f2) s3<-equal.count(data$s2,number=3) densityplot(~y| f1 + f2 + s3, data=mydata ) this produces 3 plots, *successively*, one for each value of s3. i was hoping it would produce one plot. is trellis limited to 2 conditional variables? if not, what are the appropriate commands? thanks!

hi, a) i have something like: ecdfgrp1<-ecdf(subset(mydata,TMT_GRP==1)$Y); ecdfgrp2<-ecdf(subset(mydata,TMT_GRP==2)$Y); how can i plot the difference between these 2 step functions? i could begin with ecdfrefl<-function(x){ecdfgrp2(x)-ecdfgrp1(x);} ... what next? b) if i have a vector with repeated numeric values how can i get the subset without repeated values .e.g (0,4,0,2,2)

hi, library(lattice) x<-c(-1,-1,-1,0,0,0,0,1,1,2) rng<-range(x) histogram(x,endpoints=c(rng[1]-0.5,rng[2]+0.5),nint=length(unique(x))) instead of contiguous bins, i'd like spaces between them to indicate that the data is discrete, or even better, line segments positioned at integer values. i know how to do this with plot, but i need it with histogram, so that in more complicated

hi, here's what i have: \lstset{ basicstyle=\ttfamily, keywordstyle=\bfseries, showstringspaces=false, columns = fullflexible, mathescape = true, language=R } \begin{lstlisting} lst$val<-val \end{lstlisting} ./software.tex:16:Extra }, or forgotten \endgroup. lst$ the culprit here is the $ sign. thanks. ps: i'm posting here rather than Latex is bec i guess an R user is

hi, say i have a function f and i'd like to to call it like this: 1) f(list(a=...,b=...)) but i can't do it, because f is defined as: 2) f<-function(a=NULL,b=NULL){...} is there a way that i can approximate 1), such as mapping list(a=,...b=...) to "list(a=,...b=...)" and then replacing "list" by "f", and then evaluating the expression? thanks.

hello, i have something like: out<-list() for(i in 1:n){ data<-gen(...) #fixed size data out[[i]]<- fun(data) } > object.size(out[[1]]) 6824 In principle 1 GB should allow n = 1024^3/6824 = 157347? i have about 2GB are not taken by other processes. however, I can see the memory shrinking quite rapidly on my system monitor and have to stop the simulation after only n=300. why

...e these into the list of viewable snapshots in nautilus giving the user a broader selection of restore points. In an ideal world we would like to detect the insertion of the selected media, have it automatically mounted and backup to it automatically. More info on time-slider: http://blogs.sun.com/erwann/entry/zfs_on_the_desktop_zfs So to realise this we need to be sending datasets to a zfs formatted device instead of file blobs stored on a fat32 formatted storage device etc. We would aim to provide the user with a GUI to do this and create a zpool on the selected storage device. I started out tes...

Hello, How do I get params from a form to use with a paginator? debug(params) shows this city: !map:HashWithIndifferentAccess id: "1" but in my controller, when I try to use @hotel_pages = Paginator.new self, Hotel.count(:conditions => "hotels.city_id = params[:city][:id]"), 3, @params[''page''] it doesn''t work. I suppose it''s a simple
