After trying to find if there was a color picker in the FAQs and the help, I thought I would send a post here. I was overwhelmed with all the wonderful color choices R has predefined (discovered after typing in colors()) but can't figure out what they all (by name) look like. Is there a color picker or some other method to display all those colors next to the name? I think I can put together

I'm trying to update a package and would like to crush a WARNING message for a clean build. I've been struggling with this question and haven't gotten any traction on the web either. I've got a document file (Rd) that contains the following \usage statement: \name{sample.data} \alias{sample.data} \title{CONIFERS forest growth model sample data} \description{ A list object of

When I tried to read all the entries (after searching the FAQ) for "row names xtable", I get START-INFO-DIR-ENTRY * R FAQ: (R-FAQ). The R statistical system ... ... xtable* Export data to LaTeX and HTML tables. ... For dropping the row names of a matrix `x', it may be easier to use `rownames(x) <- NULL', similarly for column ...

Dear R, I import data from spss into a R data.frame. On this rawdata I do some data processing (selection of observations, normalization, recoding of variables etc..). The result is stored in a new data.frame, however, in this new data.frame the value labels are lost. Example of what I do in code: # read raw data from spss rawdata <- read.spss("./data/T50937.SAV",

I've been trying to figure out why the following is happening.... I've got some data I'll load in from a file... rm(list=ls(all=TRUE)) trees <- read.table( "c:/cruisepak/data.txt", header=T) trees$ct <- 1 And when I create some temp variable, then split the data to perform further processing, the additional column doesn't maintain the data correctly.... mtrees

Dear List, I know this has been covered before, but I don't seem to be able to get it right. I am constructing a boxplot in lattice and can't get the scales in the correct alphebetical order. I have already read that this is due to the way factors are treated, and I have to redefine the levels of the factors. However, I have failed. As a simple example: library(lattice)

R gurus: I'm thinking about using R for website traffic analysis but didn't find anything in my web searches specific to R. If I have the webpages (simple example would contain something like three (3) static pages with a couple of links each) and parse the apache access log file (httpd-access.log), then I can populate the graph representing the website and perform whatever analysis I

I've got a newbie question and I got a little lost in the "table helps". I've got a data.frame I would like to summarize as a (and pardon for the lack of correct vernacular) data collection matrix. My data looks like, stand siteindex age acres pct.acres 1 232 116 45 8477.3105 0.56159458 2 234 121 25 11120.1530 0.73667441 3 235 132 25

I've been trying to plot the predicted values, as a line, over the data for a simple nonlinear fit with the following commands: plot( hg ~ ht ) ... define some function hg ~ ht + junk ... ... blah, blah, obtain parameter estimates and predicted values, blah... ... then... lines( sort( $predicted ) ~ sort( ht ) ) which results in a line that isn't smooth (which I knew would happen).

I'm adding a couple of vignettes to an existing package. When I make a change to the sweave file, and run the check command, c:\conifers\trunk>R CMD check rconifers I get the following message(s) in the 00check.log file: * checking for unstated dependencies in vignettes ... OK * checking package vignettes in 'inst/doc' ... WARNING Package vignette(s) without corresponding PDF:

I've got a package I would like to send out for testing and have noticed a "problem" with the \tabular portion of the help "compiler" the code for inserting vertical lines, in the tabular environment, causes the build to choke, but not the check command. C:\>rcmd build --binary -docs=all nlsystemfit \tabular{|l|c|c|c|}{ \hline Method \tab Instruments \tab

I'm in the middle of a long overdue package update, and after seeing the CRAN Task Views I thought there would be an entry, in the DESCRIPTIONS file, for that entry that appears on the package webpage. For example, http://cran.case.edu/web/packages/vegan/index.html Since it's been some time since I've updated the package, I did a little reading (R-exts.pdf) and web searching and

I've been working on a LaTeX document that contains Sweave code and cannot get MikTeX to find the Sweave.sty file. I've added the c:\rw1081\share\texmf path in the MikTeX roots (I've ven added the path in the environment variables ) but to no avail. Is there a trick to getting Sweave installed correctly when using MikTeX on Windows XP? Do I need to move/copy the Sweave.sty file to the

Dear All, I am trying to generate some Pareto random variates using the inverse method. This is really straightfoward and my R function looks as below : pareto <- function(c, a, cnt=1000) { u <- runif(cnt) x <- (c / ((u ^ (1 / a)))) mean.theo <- ((c * a) / (a - 1)) mean.gen <- mean(x) cat('Pareto mean : theoritical', mean.theo, 'generated', mean.gen,

I've been trying to figure out how to prevent a column that is the result of an aggregate function call so that I can use it in further calculations. For example, I would like to aggregate the expf for the data.frame by sp (character) and dbh (double d=rounded to integer) using the command: > st2 <- aggregate( ntrs$expf, by=list(sp=ntrs$sp,dbh=ntrs$dbh), sum ) > st2$expf <- st2$x

I've been trying to figure out how to accomplish the following... I've got a list (returned from a function) and I would like to "cbind()" the lists together to create a "cross tab" report or simply bind them together somehow the function returns a list that looks like the following: > all$BM $species [1] "BM" $vbar.nobs [1] 3 $vbar.sum [1] 54.05435

I've been attempting to create a new R package and recently removed the cygwin installation from my machine since R requires the use of the MingW tools for building an R package with C code. However, when I tried to build a source package, I found the following results: * removing junk files * building 'Rconifers_0.7-1.tar.gz' tar:

I couldn't find any reference to this in the FAQ, but is it possible to sort a dataframe by multiple columns? I've created some code, similar to the following: nspr.code <- sp.results$sp.code[order( sp.results$sp.code )] nspr.tpa <- sp.results$tpa[order( sp.results$sp.code )] nspr.code <- as.character( levels( nspr.code ) )[nspr.code] nspr.tpa <- as.numeric( levels( nspr.tpa

I've been trying to create a shlib file (using mingw instead of the cygwin -- after reconfiguring my machine, yet again) and I'm getting the following behaviour that I think is incorrect: When using rcmd shlib and explicitly listing the files to include in the build such as: C:\Sequential\Code>rcmd shlib --output=optflikam flikam.c as47.f as154.f as197.f making corrAdaptiveSim.d from
