Hi, ggplot2 can also split the graphs in different panels,
d= read.table(textConnection( "chr start1 end1 meth positive 1 1 10 20 1.5 y 2 2 12 18 -0.7 n 3 3 22 34 2.0 y 4 1 35 70 3.0 y 5 1 120 140 -1.3 n 6 1 180 190 0.2 y 7 2 220 300 0.4 y"), head=T) library(ggplot2) ggplot(data=d) + facet_grid(.~chr) + geom_segment(aes(x=start1, xend=end1, y=meth, yend=meth)) HTH, baptiste 2009/11/17 Tim Smith <tim_smith_...@yahoo.com>: > Hi, > > I was trying to get a graph in lattice with the following data frame (7 rows, > 5 cols): > chr start1 end1 meth positive > 1 1 10 20 1.5 y > 2 2 12 18 -0.7 n > 3 3 22 34 2.0 y > 4 1 35 70 3.0 y > 5 1 120 140 -1.3 n > 6 1 180 190 0.2 y > 7 2 220 300 0.4 y > I wanted the panels to be organized by 'chr' - which is ok.
