Dear R-help, I want to download the text from a web page, however what i end up with is the html code. Is there some option that i am missing in the RCurl package? Or is there another way to achieve this?

Hello, I am having a problem with write.fwf in Windows. I wrote a code to ingest a number of text files with weather data in them, process them, and then output a text file with two parts: 1) a set of column names, 2) the processed data table. I wrote and tested the program on my Mac, and it worked fine. However, on the windows machine, where I intend the work to be done, when I run the

Hi: I do not understand the returned value of NA in the following, which is a simplified version of my attempt to convert the start column of the data frame AirQual in the SwissAir package. as.POSIXct(paste('04.04.2004 0',0:3,sep=''),format='%d.%m.%Y %H') [1] "2004-04-04 00:00:00 EST" "2004-04-04 01:00:00 EST" [3] NA

Dear R-developers, A student asked me today of how to specify the limits of the x-axis. I knew that he should use xlim, but I tried to encourage him to have a try himself with the various help functions. I do not judge if he used the correct search strategy or right key words, but anyway here is what he tried: he looked at ?plot. There xlim is not mentioned. He checked ?par. There you find

Hi, I have the following function that I want to apply to a list of 14 matrices (1536 x 170) of binary data: DRes <- function(x, nr = 10000, metric = "mixed", ...) { require(analogue) require(ade4) m <- c() for (i in 1:nr) { set.seed(i) x1 <- x[, sample(dimnames(x)[[2]], length(x[1,])/2)] x2 <- x[, !dimnames(x)[[2]] %in% dimnames(x1)[[2]]] d1 <-

Hi All: I would like to extract the provider name, address, and phone number from multiple webpages like this: http://oasasapps.oasas.state.ny.us/portal/pls/portal/oasasrep.providersearch.take_to_rpt?P1=3489&P2=11490 Based on searching R-help archives, it seems like the XML package might have something useful for this task. I can load the XML package and supply the url as an argument to

Hi, All: How do I get information about the "R CMD check / build / install" process, especially regarding what software to install and how to configure it under Windows XP? I ask, because "R CMD check" complained, "gfortran: Command not found". I found 'gfortran-sjlj.exe' in 'C:\Program Files\R\Rtools\MinGW\bin', which is in the

I am trying to use winProgressBar, however I find that although setWinProgressBar updates the value on the screen, getWinProgressBar does not return this value. E.g > pb <- winProgressBar() > setWinProgressBar(pb, 0.2) > getWinProgressBar(pb) [1] 0 I tried the same with tkProgressBar, and it is working as I would expect from the documentation. > pb <- tkProgressBar() >

Hi, I have been using 'read.table' regularly to read tab-delimited text files with data. No problem, until now. Now I have a file that appeared to have read fine, and the data inside looks correct (structure etc), except I only had 15000+ rows out of the expected 24000. Using 'readLines' instead, and breaking up the data by tabs, gives me the expected result. I do not

The help files for delayedAssign and substitute both say that substitute() can be used to see the expression associated with a promise. However, I can't see how to do that. When I try the example in help file for delayedAssign I don't see substitute() extracting the promise, e.g.: > msg <- "old" > delayedAssign("x", msg) > msg <-

Hi, I have an S4 class that inherits from "array" but does not add generic implementations of the "[" method. A simplified example is: setClass("fooarray", contains="array") If I create a "fooarray" object and subset it with a one-dimensional index vector, the return value is of class "fooarray". Other variants (see below), however,
