I'm having a problem reading data to set control totals for a dataframe. I want to adjust a dataframe based on a 2-d table of values, which I get by using : > CurrentX1Sums <- as.matrix(xtabs(~tripid_nu+lineon, data=SurveyData)) > CurrentX2Sums <- apply(CurrentX1Sums, 1, sum) I've created a .csv file with new (target) sums that looks like this: tripid_nu Warner

I want to calculate "expansion factors" for elements in my dataframe based on a 2-d cross classification. Since I'll have "missing values" (many combinations will have no record) I'll need a second "expansion factor" for each "row". I've included my "work to date" below, but I'm not very close to getting this right. My

I am trying to combine two data sets, one with daily values and one with weekly values.  SurveyData conatins environmental data collected on a daily basis.  sat.data contains satellite sea surface temperature that is an average of satellite measurements over a six day period.  I would like to combine the two files so that my output file has the daily dates from SurveyData and the weekly average

I can't figure out the syntax I need to get subset to work. I'm trying to split my dataframe into two parts. I'm sure this is a simple issue, but I'm stumped. I either get all or none of the original "rows". > XTTable <- xtabs( ~ direction_ , SurveyData) > XTTable direction_ EASTBOUND

Hi R-devels, I encounter the following problem when I want to build a vignette in the package building process under Windows platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status major 2 minor

R users, I'm at a loss with a problem considering running .tex files produced by Sweave. When I run (R 2.7.0): --------------------------------------------------- #Taken from ?Sweave testfile <- system.file("Sweave", "Sweave-test-1.Rnw", package = "utils") ## enforce par(ask=FALSE) options(device.ask.default=FALSE) ## create a LaTeX file Sweave(testfile)

Dear List I just downloaded and installed R 2.12.0 and then installed R Commander . First it got RCmdr and Car, and then suggested for other packages for utilizing the full functionality- I clicked yes! I got 140 packages installed!!! Cran Mirror was UCLA... Here is the list. Is this intentional- I can see some packages like snow and multicore which are desirable but quite optional.(see list

I'm trying to learn how to calibrate/postStratify/rake survey data in preparation for a large survey effort we're about to embark upon. As a working example, I have results from a small survey of ~650 respondents, ~90 response fields each. I'm trying to learn how to (properly?) apply the aforementioned functions. My data are from a bus on board survey. The expansion in the

I want to import some "target values" to normalize elements of a dataframe. I'm summarizing the existing totals using as.matrix(xtabs(~tripid_nu+lineon, data=SurveyData)) and reading a .csv table of target values. I can't even get them to list out as similar data items. My idea is to do something like this, but I don't know how to do it in R

Hello All, I've been using R for a while and decided to test R from the svn trunk. I know that trunk is not stable, but I wanted to see if I can install and run the latest rpy on my Ubuntu 7.10 box. It installed ok, but I got the runtime error message: $ python Python 2.5.1 (r251:54863, Mar 7 2008, 04:10:12) [GCC 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)] on linux2 Type

Basic question: when I use names() to extract the name of a dataframe element, why does it have "." instead of " " between words? Context: I'm importing a CSV file of survey results for analysis. I read them like this: df <- read.csv("surveydata.csv",nrows=40,header=TRUE,

Full_Name: Allan Stokes Version: 2.8.1 OS: XP Submission from: (NULL) (24.108.0.245) I've just spent a hellish six hours trying to create my own R package with a bare bones "hello world" R function inside. I was able to create a package.tar.gz file eventually with much perseverance. My remaining problem is that when I try to install my simple package under RGui, it hangs.

Hi all, I am trying to do a 3d plot where the x,y,z axes intersects with the origin (0,0,0) using the plot3d() funtion in the rgl package without success. I looked back at the past archives on this subject and someone suggested using djmrgl package. I searched and found it, installed it but when I try to load it I get the error ... Error in inDL(x, as.logical(local), as.logical(now), ...) :

G'day all, I spend today sometime playing around with R under Windows since our lecturing starts in 2 weeks again and our IT guys want to know which version to put onto our lab machines. I noticed the following: Under R-2.2.1, I obtain the following output: > R.home() [1] "C:\\PROGRA~1\\R\\R-22~1.1" and if I run "help.start()" under R, I obtain a file

Hi all, I am trying to compile Rgraphiz on Windows 7 64bit with R-2.13.0. I have installed Rtools213.exe from [1]. The 64bit packages in [2] provided me with the 64 bit version of graphviz. After intalling the binary version Rgraphviz 1.30 (in 32bit) it complains (as expected) that: > library(Rgraphviz) Error: package 'Rgraphviz' is not installed for 'arch=x64' I

Hi, everyone, I am just trying to use Rcpp in my computer, and I would like to try a simple example from website, but R keeps reporting me error. I am using Windows XP, and has installed Rtools and GSI. Here is the response: > src = ' + Rcpp::NumericVector xa(a); + Rcpp::NumericVector xb(b); + int n_xa = xa.size(); + int n_xb = xb.size(); + + Rcpp::NumericVector xab(n_xa + n_xb - 1);

Dear R development: I'm not sure if this is the appropriate list, but it's a start. I would like to put together a package which contains a CUDA program on Windows 7. I believe that it has to do with the Makeconf file in the etc directory. But when I just use the nvcc with the shared option, I can use the dyn.load command, but when I use the is.loaded function, it shows FALSE.
