Simple question: is it true that polygon (x, y, col=vec, border=vec, ...) will cycle through the vec colors for fills but not for the border colors when sending multiple polygons? thanks, Denis White US EPA, 200 SW 35th St, Corvallis, Oregon, 97333 USA voice: 541.754.4476, email: white.denis at epa.gov web: www.epa.gov/wed/pages/staff/white/

I'm using R 1.4.1 under Windows 2000 and am experiencing difficulty installing a package. I've included an example output using Rcmd build, but the same problem occurs with Rcmd check and Rcmd INSTALL. The error (make[1]: /bin/sh.exe: Command not found) is not a new one - it's referenced in readme.packages among other locations. I've placed a copy of sh.exe in C:\bin, but it

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:

Does anyone know of any issues with nesting source() calls within multiple scripts? I have at least one script which always finds errors when I source it but runs fine when run on its own. It containd source() calls to other scripts and it seems to fail during the first nested source() command. Ken Kenneth B.

Is there any way to put an argument into an object name. For example, say I have 5 objects, model1, model2, model3, model4 and model5. I would like to make a vector of the r.squares from each model by code such as this: rsq <- summary(model1)$r.squared for(i in 2:5){ rsq <- c(rsq, summary(model%i%)$r.squared) } So I assign the first value to rsq then cycle through models 2 through

I am converting some S-PLUS scripts that I use for creating manuscript figures to R so that I can take advantage of the plotmath capabilities. In my S-PLUS scripts I like to use the key() function for adding legends to plots, and I have a couple of questions regarding using the legend() function in R. 1) is there a way to specify different colors for the legend vector of text values? 2) is there

I've been developing a package and have been getting the following warning when running the check command: * checking S3 generic/method consistency ...

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 R wizes, I have a data.frame of species abundances with column names consisting of 4 letter codes then an underscore and a number like this: abco_1, abco_2, abco_3, psm_1, psme_2, psme_3, etc. I would like to get an identifier for all the abco, and psme and other species etc. I used spec.fact<-substring(names(spec.count),1,4) To make a vector of the first 4 letters of

I thought I had plotted a map of oregon and washington and overlayed some points using R. Is that possibe since I can't seem to find the source file I used or commands for plotting maps and points?

Hi all - I am far from fluent in R and need some help polishing up a figure I am trying to create. I wish to make a "tileplot" (from package extraLattice) where the x axis is time (months; may - sept) and the y axis is space (fishery management zones). Here is my code so far: tileplot(effort~month_num*-area_num,mae,col.regions=topo.colors(100), border =

I can't believe I'm having such a hard time with this and I haven't been able to find out how to solve this... lab <- expression( paste( hat(v), as.character(round(y.hat,2)), ",", hat(sigma)^2, as.character(sigma.hat)) ) text( x=pt$x+2, y=pt$y,labels=lab ) ## the text should be \hat{y} = <value of y.hat>, \hat{\sigma}^2 == <value of sigma.hat> and R

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

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

Hello, Based on reading the Windows FAQ and searching the list archives, I gather that in the past, Active Tcl 8.3.x has been required in order to use the tcltk package under R for Windows. Apparently Active Tcl 8.4.1 is now stable, and I was wondering whether this newer release of Tcl can be used with R under Windows? I've not used Tcl/Tk before but I am considering using it for some
