Hello everyone, I have a variable with several categories and I want to convert this into dummy variables and do logistic regression on it. I used model.matrix to create dummy variables but it always picked the smallest one as the reference. For example, model.matrix(~.,data=as.data.frame(letters[1:5])) will code 'a' as '0 0 0 0'. But I want to code another category as

Is there a simple way to decompose the upper triangle of a correlation matrix to a linear list; For example: X Y Z X 1 2 3 Y 2 1 4 Z 3 4 1 so you get a list like: xy 2 XZ 3 YZ 4 I suspect you can do it with a matrix transformation, but that beyond me at present.

I am currently the only use-R at my company, but they are considering buy a more powerful server and letting multiple people use it. They asked me if R supports client-server setups. I know S+ has a server version that does that. I didn't find anything about that on CRAN, but hopefully someone can correct me. I did see some stuff about R web servers

Hi all I have a question about plotting line types and legends. Here's a short piece of code to demonstrate: x <- y <- seq(1,10) plot(x,y, type ="l", lty="33") lines(x,y+1, lty=1) legend( 8,2,legend=c("lty=1","lty=\"33\""), lty=c(1,"33") ) On my system (see below), the line types in the legend are not the same as in the

I receive the following error: Error in match.arg(x, c("bottomright", "bottom", "bottomleft", "left", : 'arg' should be one of bottomright, bottom, bottomleft, left, topleft, top, topright, right, center In addition: Warning message: longer

Hello, I have a time series plot drawn using 3 different colored lines, each line corresponds to different category group. I'd like to put legends on the plot. I am using "legend" to do this, however, I can either specify lty or col in legend. Will I be able to do the following in the legend box: a solid black line then g1, a solid red line then g2, a solid blue line then g3?

I am trying to compose some documentation for a package I hope to release soon. However when I do the following: R CMD Rd2dvi --pdf mypackage.Rd I get two mainly blank pages prepended to the top of the document - the only text on either (at the top of the first page) is as follows: hyperindex,colorlinks,pagebackref,linktocpage,plainpages=false,linkcolor=Blue

Hallo R-users, I do not understand how to specify the correct line and symbol types in the legends of a lattice xyplot. This is what I tried, but the line types and symbol in the graph are not seen in the legend. Any help is appreciated. Thanks, Gerrit. library(lattice) s<-rep(1:3,len=10) x<- 1:10 y<- x+s+rnorm(10) d<-data.frame(s,x,y) xyplot(y~x, groups=s,data=d,

Hi listers, I want to make lattice plots xyplots with the indication of legends inside each panel with only the points and the lines actually ploted inside each given panel according to the group(ing) factor. The code below shows what I have achieved so far and I hope will make clear what I want to have. It seems to me that my solution is a very "dirty hack" and there certainly is

Hello, placings of legends is sometimes tricky. For placing outside the plot region I found locator to be useful. Unfortunately, the click defines the upper left corner. Is there a way to change this corner (say lower right corner)? Thanks, Christian

Achim: Thanks again for the conference. We had good fun. I have 2 requests: 1) I'd like to email my R-foundation membership to you. I will scan the form and send just like I did for the meeting. 2) I want a useR t-shirt. After lots of drinking and discussion with Fritz Leisch at dinner on saturday, I feel there will be no chance for an official T-shirt. My question is: any advice/

I discovered a little problem when using the Windows NT release of R 1.0.1, and it's still there in R 1.1.0. The boiled down version is this: I want to draw the following plot and put it into a Postscript file: x <- c(1,2,3,4); y1 <- c(1,2,3,4); y2 <- c(2,2,2,2) Fred <- c(1,2) postscript(file="d:/Bob/Papers/IFM/try2.ps") plot(x,y1, type="l")

Hi all Humbly begging forgiveness for bothering the list with yesterday's lame--arsed question. Postscript, being a vector graphics file format, is, um, resolution independant. The problem as Peter pointed out was with the gimp, which defaults to 100dpi resolution when viewing postscript files. I have another (lame?) question. I have noted that when I produce a graph with multiple

Dear All, I am producing a figure with many curves on it. How do I make the legends for all those curves smaller so that it can fit the figure itself? The commands I used for ploting are: plot(x1,y1,col=1,lty=1) lines(x2,y2,col=2,lty=2) ... legend(0.3,0.4,c("name1","name2",...),col=1:20,lty=1:20) Any tips for making the legend fit the figure will very welcome! Thanks! Best,
