Here are 3 approaches: barplot( 1:12, xlim=c(0,12), width=1, space=0, names.arg=substr(month.abb,1,1)) lines( (1:12) - 0.5, 1:12, type='b', lwd=2, col='red' )
### or tmp <- barplot(1:12, names.arg=substr(month.abb, 1,1)) lines( tmp, 1:12, type='b', lwd=2, col='red' ) ### or library(TeachingDemos) tmp <- barplot(1:12, names.arg=substr(month.abb, 1,1)) updateusr( tmp[1:2], 0:1, 1:2, 0:1 ) lines( 1:12, 1:12, type='b', lwd=2, col='red' ) -- Gregory (Greg) L.
