Dear colleagues, Could I get some assistance using postForm() to scrape the business names and addresses at this website: http://www.brantford.ca/business/LocalBusinessCommunity/Pages/BusinessDirectorySearch.aspx I've read through (http://www.omegahat.org/RCurl/RCurlJSS.pdf) and scoured the web for tutorials, but I can't crack it. I'm aware that this is probably a pretty basic

Hi, I'm trying to get a list of addresses from http://tatts.com/racing/outletsearch based on a list of postcodes (zip codes) and states. For example, I'm looking for State = 'Northern Territory' and Postcode = '0800'. The list I'm working off is about 500 long so I was hoping to find a way to script this in R. I regularly us readLines and the XML library to scrape

Hello, I am going through Zhao's RDataMining PDF, and to redo all the graphics on my computer, I need several packages, 'coin' and 'party' to name two. I get the following error: > install.packages("coin") Installing package(s) into ?/home/sven/R/i686-pc-linux-gnu-library/2.15? (as ?lib? is unspecified) trying URL

Awaiting some suggestion. Was my question not very understandable? Please let me know how can I offer more elaborate clarification. Additionally, I would like to solve the determinant of "p1" for the values of "z" (I am working with some multivariate time series modelling). When I use det() function, it am getting error that, that function is not for objects with class

I have some questions and observations about these: Will these replace manually setting options(CRAN), which doesn't work in R-2.1.0? In R-2.1.0, setRepositories() looks to see if options("repos") contains a CRAN entry and will not override that CRAN entry even if the $R_HOME/etc/repositories file (which setRepositories reads from) contains a CRAN entry. Why is this? The user

I currently set the Bioconductor repository in my .Rprofile using this code (which needs editing for every version number change of Bioconductor): # Choose repositories repos <- structure(c(CRAN="http://streaming.stat.iastate.edu/CRAN", CRANextra="http://www.stats.ox.ac.uk/pub/RWin",

let consider following matrix : mat <- matrix(rnorm(45), 15) Now I want to convert it to a list object "mat_list", which will have 15 elements and each element will again be a matrix with 3 rows and 3 columns. How can I do that? Thanks, -- View this message in context: http://n4.nabble.com/Matrix-to-list-object-tp989738p989738.html Sent from the R help mailing list archive at

Dear all, I have following two list object, both are basically collection of matrices : dat1 <- matrix(rnorm(25*6), ncol=6) dat1 <- split(dat1, seq(5,25,by=5)) dat1 <- lapply(dat1, matrix, ncol=6) dat2 <- matrix(rnorm(25*4), ncol=4) dat2 <- split(dat2, seq(5,25,by=5)) dat2 <- lapply(dat2, matrix, ncol=4) Now I want to replace last 4 columns of each matrix at "dat1"

Hi all, I have a expression like that : > rep(2,4) [1] 2 2 2 2 Now I want to write it as "2222" through some automated way. Is there is function for doing that? I have tested with paste(), but count not get any desired result.

Dear all, My gRbase package imports functionality from the bioconductor packages graph, Rgraphviz and RBGL. To make installation of gRbase easy, I would like to have these bioconductor packages installed in connection with installation of gRbase, but to do so the user must use setRepositories() to make sure that R also installs packages from bioconductor. Having to call setRepositories causes

Dear all, Ket say I have 3 matrices : mat1 <- matrix(rnorm(16), 4) mat2 <- matrix(rnorm(16), 4) mat3 <- matrix(rnorm(16), 4) Now I want to merge those three matrices to a single one with dimension 4*3=12 and 4 wherein on resulting matrix, row 1,4,7,10 will be row-1,2,3,4 of "mat1", row 2,5,8,11 will be row-1,2,3,4 of "mat2" and row 3,6,8,12 will be row-1,2,3,4 of

If no 'type' is specified, download.packages("pkgname") will download source packages (.tar.gz files), even on Windows. However, the help says type character string, indicate which type of packages: see install.packages. and on Windows, install.packages defaults to downloading binary packages. Is this intended behaviour on the part of download.packages? This is on R
