Using sub to get captions in barplots
..., see below), the captions are split on more than 1 line. Is there a way to get the caption on a single line?

Hopefully an easy error bar question
...it into two levels so i have males and females, so my graph basically has four bars on it. I know how to add eror bars for instance when there is only one level eg lookng at the diffrence between male and female lizards and tree height and have used the code: error.bars<-function(yv,z,nn) { xv<- barplot(yv,ylim=c(0,(max(yv)+max(z))),names=nn,ylab=deparse(substitute(yv) )) g=(max(xv)-min(xv))/50 for (i in 1:length(xv)) { lines(c(xv[i],xv[i]),c(yv[i]+z[i],yv[i]-z[i])) lines(c(xv[i]-g,xv[i]+g),c(yv[i]+z[i], yv[i]+z[i])) lines(c(xv[i]-g,xv[i]+g),c(yv[i]-z[i], yv[i]-z[i])) }} Have then w...

Calculating angle of a polyline
Assuming your polyline is defined by two vectors, one for the x coordinates, one for the y coordinates, you can try the following library(NISTunits) polyangles <- function(xV,yV) { stopifnot( (length(xV)==length(yV)) && (length(xV) >= 3)) v <- function(i) { c( xV[i]-xV[i-1], yV[i]-yV[i-1])} vlen <- function(v) { sqrt(sum(v*v)) } lV <- rep(NA_real_,length(xV)) for ( i in 2:(length(xV)-1) ) lV[i] <- acos( sum(v(i)*v(i+1))/(vlen(v(i))*...

predicting values from multiple regression
Hey List, I did a multiple regression and my final model looks as follows: model9<-lm(calP ~ nsP + I(st^2) + distPr + I(distPr^2)) Now I tried to predict the values for calP from this model using the following function: xv<-seq(0,89,by=1) yv<-predict(model9,list(distPr=xv,st=xv,nsP=xv)) The predicted values are however strange. Now I do not know weather just the model does not fit the data (actually all coefficiets are significant and the plot(model) shows a good shape) or wether I did something wrong with my...

Rug plot curve reversal
Dear R-help Can anyone tell me why my curve appears the wrong way round on a rug plot? I am using the same code as on pg 596 of the Crawley R-book. mod<-glm(mort~logBd,binomial) par(mfrow=c(2,2)) xv<-seq(0,8,0.01) yv<-predict(mod,list(logBd=xv),type="response") plot(logBd,mort) lines(xv,yv) I've tried swapping xv and yv around but no luck. Thanks, Pete [[alternative HTML version deleted]]

centos 5 with mplayer and xv driver
Hi all I am trying to get mplayer working on centos 5. On centos 4.X I just did a ./configure and make and make install for mplayer.... Can use prepaged mplayer for other reasons. anyway, when I play a video I cannot get it to use the xv driver (acceleated video). What package might I be missing or not installed to get the xv driver ??? I am using the binary nvidia drivers (latest version). Thanks so much... Jerry

more cubes and 3d metaphoric objects...
hi how about having more cubes to fly around in 3d space. though at first thought this might appear unessacary as who needs so many desktops? So i thought, why not have special cubes (as well as the original cube of course) and these special cubes, instead of cubes, be 3d metaphric objects for specific tasks such as a radio, or ipod or whatever for music a cinema for movies arcade thingo for
