Hi all, I have a very large binary vector, I wish to calculate the number of 1's over sliding windows. this is my very slow function slide<-function(seq,window){ n<-length(seq)-window tot<-c() tot[1]<-sum(seq[1:window]) for (i in 2:n) { tot[i]<- tot[i-1]-seq[i-1]+seq[i] } return(tot) } this works well for for reasonably sized vectors. Does

Hello All, I have had considerable bad luck with attempting the following with for loops. Here is the problem: # Suppose we have a data.frame with the following data, which can be considered a type of edgelist (for those with networks backgrounds): # # V1 V2 # 1 A # 1 A # 1 B # 2 A # 3 C # 3 A # 3 C # 3 B # # I want the output of the function to produce a matrix, such that #each factor of

Well, you cannot easily export stuff from an executable and this is the main issue here. (And you cannot e.g.

Dear R developpers, I am a user of Splus since many years and I have developped lots of functions to plot graph of data and model results of irregular or regular times series. In Splus regular times series are created using the rts function and irregular time series using the its functions. In both cases, times is given as a numeric vector. There is no problem in plotting a regular and an

Dear R-users, I have 1 remark and 1 question on the inclusion of interactions in the gam function from the gam package. I need to fit quantitative predictors in interactions with factors. You can see an example of what I need in fig 9.13 p265 from Hastie and Tibshirani book (1990). It's clearly stated that in ?gam "Interactions with nonparametric smooth terms are not fully

Hi Buit the Kaleidoscope example under MinGW and everything runs fine except when I try the following example in Chapter 6: extern printd(x); printd(123); where printd is the library function defined in C as extern "C" double printd(double X) { printf("%f\n", X); return 0; } The error message is: LLVM ERROR: Program used external function

Dear all, Has anyone written R code for partial Mantel Tests- as described for instance in Legtendre & Legendre (1998) ? In other words, in a community ecology analysis, I would like to calculate the correlation between two dissimilarity matrices, controlling for a third distance matrix representing geographical distances between sites. Thanks! Christophe Bouget Biodiversité et gestion des

Dear all, I found that printing with 'cat' is very slow. For example in my machine this snippet __BEGIN__ # I need to resolve to use this type of loop. # because using write(), I need to create a matrix which # consumes so much memory. Note that "foo, bar, qux" object # is already very large (>2Gb) for ( s in 1:length(x) ) {

Hi all, i'm new to the list and here's my first question : I'm trying to install several printer drivers on my samba server with imprints. I did a package with the NT/2000 and W9x drivers and the mkprintpkg command. Then I used the command install_printer_drivers.pl to install the files in the appropriate directories. So now i'd like to check the drivers available and the

[cross-posted from www.tek-tips.com] Dear samba forum, I've now wasted most of a weekend on this issue, so now it's time to swallow my pride and ask for help! Background: My main home computer died. I can't afford to replace it right now, so I'm attempting to retread an old AMD PC into a linux print/file server. Clients are a mixed bag of Windows XP home/professional PCs. The

Dear R users, Up to now, I only used precompiled packages. As I am working on vegetation ecology, I would be interested in using a package not stored by CRAN called labdsv_0.9-1.tar.gz and developped by Dave Roberts at the National Center for Ecological Analysis and Synthesis (unfortunately I did not find any corresponding .zip file). Although I tried to follow the proposed guidelines to

You can call them the same way a C++ file compiled with llvm-g++ would call them. Essentially, it's complicated enough that you probably don't want to do it for any interface of
