Thanks for your email... yes, I had tried that "bw" thing.. for some reason it does not seem to work.. could not figure out where I am wrong...
Below is an example for your convenience.. you might notice that the density plots appear to be a curve of connected segments. Changing breaks, nint or bw didn't seem to help. ############ library(reshape) set.seed(13454) aa <- data.frame(a1=rnorm(500),b1=rnorm(500,0.8),c1=rnorm(500,0.5),cat1=rep(1:5,each=100)) ab <- melt(aa,measure.vars=c("a1","b1","c1")) histogram(~ value|variable,ab,breaks=NULL,nint=10,type="density",layout=c(2,2),as.table=T,scales=list(relation='free'), panel=function(x,lqp=c(0.05,0.975),...) { panel.histogram(x,col='lightblue',...) panel.densityplot(x,col.line='blue',lwd=1.75,bw=2,...) panel.abline(v=c(quantile(as.vector(x),prob=lqp,na.rm = T)), col="dark green",lwd=2,lty=2) }, strip=strip.custom( strip.names=F, strip.levels=T, par.strip.text=list(cex=0.75)), ) ############ Thanks again, Santosh On Thu, Apr 15, 2010 at 12:41 AM, Paul Hiemstra <p.hiems...@geo.uu.nl>wrote: > Santosh wrote: > >> Dear R gurus... >> >> How do I control "smoothing" of a density plot in panel.densityplot when >> using histogram? >> >> Thanks much, >> Santosh >> >> [[alternative HTML version deleted]] >> >> >> ______________________________________________ >> 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. >> >> > Hi, > > From ?panel.densityplot, argument darg, I was referred to ?density.
