Hello all, I want to read a table from a given web page. If I do something like > str="http://www...." # this is the web address > aux1 <- url(str,open="rt")# open connection > aux2 <- readLines(aux1) # read web page aux2 contains the html file. I want to extract the table from the html file. Is there a function html2R, the opposite of R2html?

Hi all, I'm trying to read a data set into R, but the file is messy, so I have to do it partially. The whole data is in a .txt file, and the values are separated by a space. So far ok. The problem is that in this file, not all the lines have the same number of elements, and the reading stops. And I loose the reading of the previous lines. ex. of data set: 11 12 13 21 22 23 31 32

Buenas, Tengo un monton de variables que quiero meter en un data.frame. Las variables las he ido extrayendo de la siguiente manera for(i in 1:240) { #saco el inicio de cada refrigeracion aux1 <- paste("inicio.refri", i, sep = ".") assign(aux1,datos[which.max(datos[,109+i]),"LogDateTime"]) } Y quiero buscar una funcion que me permita meter esas 240

Hello. I have n files in a directory: file1, ..., filen. I read them with the following commands: list=scan(file="list",what=list(nom="")) # in the file list, I have all the filenames. n=length(list[[1]]) for (i in 1:n){ aux <- paste("p",i,sep="") assign(aux, as.matrix(read.table(list[[1]][i]))) } R creates the matrices p1,p2,...,pn. I want

I'm having an interesting/odd problem with nfs (I think). We recently (Monday/Tuesday) upgraded our file server from an ancient redhat 7.3 system to a shiny new centos 6.4 system. We don't see any issues between the other centos boxes, but things get a bit weird when we start mounting on the old solaris clients. The initial symptom was that the 'tab complete' wasn't

Dear List Members, I have encountered two problems when using the step function to select models. To better illustrate the problems, attached is an R image which includes the objects needed to run the code attached. lm.data.frame have factor variables with 3 levels. The following run shows the first problem. AICs (* and **) are different. I noticed that the Df for rs13482096:rs13483699 is 4,

Sirs; I have read your web site page current issues and debugging and I am interested in how to debug a rsync issue which ends with the following message: io timeout after 60 seconds -- exiting rsync error: timeout in data send/receive (code 30) at io.c(181) I have compiled rsync on a hpux 11.11 server and I am using rsync-2.6.4.

Konrad, et al, I am seeing visual corruption (almost like an interlacing problem) with i915 under Xen on some platforms using linux-3.8. See attached file for an example of the visual corruption. This particular platform is an HP Elitebook 2540p The same kernel and ramdisk, when booted as native linux does not show this corruption. dmesg is attached, as well (out.txt) - but I did not see

This may not be the proper place to raise this question but I've had little luck elsewhere. After trying again, unsuccessfully this time, to install the proprietary NVIDIA driver, I've decided to focus my efforts on the open source Nouveau driver. I've seen video drivers blamed for varying degrees of "freeze on resume" but I'm not certain that's what I'm up

I?m new to R so maybe this issue has been asked before and I still could not read the complete set of past messages sent to the list. I found a weird behabiour that I will explain with a simple example. Lets consider the following block of commands: > x <- diag(c(1,4,10)) > x [,1] [,2] [,3] [1,] 1 0 0 [2,] 0 4 0 [3,] 0 0 10 > invx <- x^-1 > invx

Hello All, I am a R newbie and am probably misinterpreting something really obvious... In the Rcmdr package there is a scatter3d() function that can fit a curve and also provide coefficients for the model. If I'm understanding this right, I think it's calling the lower level stats package function lm(), which is the part that actually does the curve fitting. Anyway, what has me
