All, I've been using "sub" (subtitle) instead of "main" such that captions are below figures produced by xyplot. This works fine and captions are on a single line. However, when I try this for bar plots with error bars (altering the error.bars function form Crawley's The R Book, see below), the captions are split on more than 1 line. Is there a way to get the caption on a single line?
Cheers, David y.bar.new = c(30, 15) se.ybar.new = c(2,3) error.bars(y.bar.new, se.ybar.new, c("Control (n=18)", "CKD (n=18)")) error.bars<-function(yv,z,nn){ xv<-barplot(yv,ylim=c(0,(max(yv)+max(z))),names=nn,ylab="Total five hour potassium excretion (mmol)", sub= "Figure 1B: Hour 1-5 potassium excretion") 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])) }} > sessionInfo() R version 2.7.1 (2008-06-23) i386-apple-darwin8.10.1 locale: en_US.UTF-8/en_US.UTF-8/C/C/en_US.UTF-8/en_US.UTF-8 attached base packages: [1] grid stats graphics grDevices utils datasets methods base other attached packages: [1] lattice_0.17-8 nlme_3.1-89 loaded via a namespace (and not attached): [1] Matrix_0.999375-11 lme4_0.999375-24 tools_2.7.1 ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
