[R] Alternative to xyplot()?
Hello list, Is anyone aware of a non-lattice-based alternative to xyplot()? Thanks!

I was thinking of the groups functionality, as illustrated below: grps-rep(c(1:3),10) x-rep(c(1:10),3) y-x+grps+rnorm(30) library(lattice) xyplot(y~x,group=grps, type=c(r,p)) __ R-help@stat.math.ethz.ch 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.

library(lattice)
xyplot(y~x,group=grps, type=c(r,p))
The points (type p) are easy, the regression lines (type r) are a little
harder. How about:
plot(y~x,col=grps)
invisible(mapply(function(z,col) {abline(lm(y~x,data=z),col=col)},
split(data.frame(x,y),grps),1:3))

Re: [R] Alternative to xyplot()?
What's wrong with lattice? Here's an alternative:
library(ggplot2)
ggplot(data=data.frame(x,y,grps=factor(grps)),
mapping=aes(x=x,y=y,colour=grps)) + # define data
geom_identity() +# points
geom_smooth(method=lm) # regression line
